What does science say about health risks from widely used glyphosate on U.S. farms? An expert weighs in.

Despite thousands of lawsuits and some scientific studies linking glyphosate, the active ingredient in the herbicide Roundup, to serious human diseases, the compound remains the most popular herbicide for farmers worldwide.

In the U.S., where Roundup is the most commonly used herbicide, many consumers have questions about the health risks glyphosate may pose. According to epidemiologist Dr. Katelyn Jetelina, writing for Your Local Epidemiologist on Substack, the most pressing questions are: "Does glyphosate cause cancer? And how much exposure is actually risky?" She provides some background and details about what "the scientific evidence actually says."

Like many chemicals, natural and synthetic, the dose determines toxicity. "So, at what dose is glyphosate poisonous? The LD50 in rats (the dose that kills half the test animals) is around 5,600 mg/kg body weight," Jetelina explains. "Table salt is roughly 3,000 mg/kg. By that classic measure, glyphosate is less acutely toxic than salt."

Still, many people who work on farms or live near farms may be regularly exposed to "a lot of glyphosate," Jetelina writes. "Among the general public, there are many questions about low-dose, cumulative exposure from multiple sources over long periods."

Correlation maps that show the number of non-Hodgkin lymphoma cases in counties that spray the most glyphosate seem to point to a relationship between the two. Jetelina adds, "But correlation alone doesn’t establish cause, which is why animal and human studies matter."

Tests on rats, which have often been cited as the most alarming, and observation testing on humans, indicate the same thing: "At very high exposure levels, there may be some cancer risk," Jetelina explains. "But that’s about as far as the science currently takes us."

The U.S. EPA, the European Food Safety Authority, Health Canada, and regulatory agencies in Australia and Japan have "all concluded that glyphosate is 'unlikely to be carcinogenic to humans' at realistic exposure levels," Jetelina writes. Those regulatory bodies looked at "how much glyphosate people actually encounter and asked what is the probability of harm? Your actual exposure is what determines your actual risk."

In daily life, an average American would be hard-pressed to consume enough glyphosate to do any harm. To exceed EPA's herbicide residue limits, a "150-pound adult would need to eat roughly 50 pounds of oats every day," Jenelina writes. Organic certification doesn't allow synthetic herbicides, so in practice, most herbicides can be avoided by purchasing organic foods.

For farm workers who mix and apply glyphosate, Jenelina advises using personal protective equipment consistently to prevent unnecessary exposure. People who live near farms can help protect themselves from spray drift by "knowing your local agricultural calendar and keeping windows closed during application are the first steps."

After a jarring ICE raid at a horse racing track, residents of a tiny Idaho town measure the aftermath

Some residents of Wilder, Idaho, say the town hasn't been the same since federal Immigration and Customs Enforcement agents descended on an off-the-beaten-path horse racing track and detained roughly 100 Latinos who were working or attending the races. 

The horse track, known as La Catedral Arena, had been a place where immigrant families gathered to enjoy food and racing together, reports Anna Griffin of The New York Times. Few whites ever attended the races or questioned track activities.

County, Idaho. (Wikipedia)

Sixty percent of Wilder's 1,725 residents are Latino, and most residents take pride in living in harmony. But on Oct. 19, things changed. ICE agents, including a swarm of gun-toting agents on the ground, a helicopter, and the agency's signature SUVs, descended on the track during the busiest time of day. Agents rounded up nearly 100 Latinos and later deported 75.

The raid did more than "crack an alleged gambling ring and increase deportation numbers," the Times reports. "It shattered Wilder’s innocent belief that its out-of-the-way location and deep-red politics could isolate the town from raids." 

Wilder resident Chris Gross, who farms sweet corn seed and mint, expressed concern about how the raid might limit immigrant farm workers. She told Griffin, "We rely on Hispanic labor." 

"The raid 'nearly destroyed' the community, said David Lincoln, a longtime Wilder resident and executive director of a nonprofit economic development agency serving rural towns in western Idaho," Griffen writes. Griffin adds, "Wilder won’t really know the impact until planting season begins this spring."

The day after the raid, at least half of Wilder's students didn't show up for class. Griffin reports, "Gross, who is white, said anyone who sees a black SUV roll through town, regardless of their race, 'freezes up.'" 

Still, the town's mayor, Steve Rhodes, claims the raid "has had 'zero effect' on the town," He told the Times, "These were not our people. What happened out at that track had nothing to do with Wilder.”

Opinion: Federal policies targeting farming workforce and income need to be addressed before a bailout is needed

incomes. (Photo by Richard Bell, Unsplash)

U.S. farmers face a rocky future as federal policies cut into sector labor and profitability. "Agriculture stands out as acutely vulnerable to President Donald Trump’s avalanche of tariffs, mass deportations and potential new regulations," writes The Washington Post editorial board. "Farmers don’t need a bailout. They need relief from overregulation and excessive immigration enforcement."

Soybean and corn farmers are "panicking about Trump’s trade wars, which expose them to retaliation from China, Canada and Mexico, their most important export markets," the board writes. Ranchers and produce growers have stood by and watched as "agents from Immigration and Customs Enforcement descended en masse across fields to detain and deport agricultural workers."

Agriculture Secretary Brooke Rollins suggested that Medicaid recipients, who will soon need to meet program work requirements, could replace the migrant workers ICE deported. Her comments "landed like an insult in farming communities," the board adds. 

Dave Puglia, president of Western Growers, a lobby group for produce growers in the West, told the Post, “The men and women who harvest our crops are highly skilled. To anybody who believes they can pick and pack in the field, go try it.”

The current administration’s solution for farmer woes is to send subsidy payments, but those will only help certain types of farms. "Trump’s tax bill included $66 billion in new spending for farm programs," the board writes. "While the generous income support programs may keep many farmers from switching political allegiances, the hit from the Trump administration’s policies won’t be easy to fix."

Using agriculture as political fodder is "unusual in American politics," the board adds. "Yet to be seen are the full economic consequences of going after America’s food producers. . . .On priorities that come at the expense of farmers, it is likely to do some real damage to the food supply. The better approach is to avert the damage, rather than wait to bail out farmers once they grow desperate."

When temperatures sizzle, outdoor laborers often continue to work; a new OSHA rule could help keep them safe

To help outdoor workers stay healthy amid U.S. heat waves, last year the country took steps "towards protecting millions of workers from the impacts of extreme heat on the job," reports Frida Garza of Grist. In July 2024, the Occupational Safety and Health Administration published "its first-ever draft rule to prevent heat illness in the U.S. workforce."

OSHA's proposed rule would "require employers to provide access to water, shade, and paid breaks during heat waves," Garza writes. "In the U.S., the Environmental Protection Agency estimates that 986 workers died from heat exposure on the job from 1992 to 2022, or about 34 per year."

While the Trump administration has sought to undo several workplace regulations, the drafted heat protection rule has moved forward. "The agency is currently in the middle of soliciting input from the general public about the proposed policy."

Some labor experts say the proposal is moving through the process quickly, but labor advocacy groups "focused on workers along the food supply chain, say workers have waited too long for basic life-saving protections," Garza reports. "Even in a best-case scenario, regulations would not be on the books for another 12 to 14 months." In some cases, it takes several more years for a rule to be fully implemented.

Given the lengthy timeline, several advocacy groups are working to educate employers and give outdoor workers a voice in public forums. The group "WeCount" in South Florida "has spearheaded multiple campaigns to draw public attention to how sweltering temperatures impact outdoor workers in the region, including plant nursery workers," Garza explains. "WeCount members are trying to publicize the risks that agricultural workers take on."

Getting consumers to care about their workforce enough to take action is one of the best ways outdoor employees can lobby for heat protections. Garza reports, "The Fair Food Program, first established by tomato pickers in 2011 in Florida, has won stringent heat protections for farm workers in part by building strong support for laborers’ demands among consumers."

As farm raids continue, farmers may not have enough workers to harvest crops; some in GOP want reforms

Despite President Donald Trump's aggressive push to oust unauthorized immigrants from the United States, a growing number of Republicans see the current lack of illegal border crossings as an opportunity to push for a shift in priorities that includes legislation that protects farm workers from deportation.

GOP backers for immigration change warn that "if farms can’t hire all of the workers they need, they risk being forced to leave crops to spoil or paying more for labor, which could lead to higher food costs," report Olivia Beavers and Michelle Hackman of The Wall Street Journal. Some GOP members "argue the party should focus on changing immigration law to allow some workers to gain temporary legal status and make sure people can remain on the job."

Still, House Speaker Mike Johnson (R., La.), "who controls what bills come to the floor, signaled any immigration overhaul would face an uphill battle," Beavers and Hackman write. 

The Labor Department recently "established the Office of Immigration Policy, which aims to streamline and modernize the process for employers — including agricultural employers — as they navigate the various programs that include supporting legal pathways to work," Beavers and Hackman add. 

While the U.S. has several visa programs for agricultural workers, many farmers say that the programs are cumbersome and fail to meet the needs of certain types of farms. According to the Wall Street Journal article, "People using the visas also need to return to their home countries for a chunk of each year, meaning farms with year-round work, like dairy farms, can’t use them."

Republicans backing immigration reform face push-back from the Trump administration and potential fallout from another failed immigration reform bill. "Administration officials have repeatedly pledged to hit a goal of arresting a million unauthorized immigrants in Trump’s first year in office, though they have hit less than a fifth of that number so far," the Journal reports. "Farm areas skew heavily toward Republicans, raising the political stakes for the party."

U.S. dairy farmers see an increase in I-9 audits for immigrant workers as their newest labor challenge

Beyond international tariffs, bird flu and possible Immigration and Customs Enforcement raids, U.S. dairy farmers have a new worry to add to their unpredictable livelihoods: I-9 audits. "Nervousness and frustrations are spreading across the dairy industry," reports Tyne Morgan of Dairy Herd Management. "With reported flaws in the E-Verify system, the audits are resulting in dairies being forced to fire employees who are found to have illegal documents and only given 10 days to do so."

When I-9 audits occur, worker documents are examined, and it's often discovered that "employees submitted either illegal paperwork or forms that weren’t theirs," Morgan explains. "There’s no way for a dairy to know. That’s what the E-Verify system is meant to do." 

Although only dairies in South Dakota and Texas have been audited so far, increased inspections aren't welcome news for dairy farmers, who often rely on immigrant labor to perform much of the constant and strenuous work required. Tyne explains, "The dairy industry seems to be on an island when it comes to finding a legal workforce. Dairies aren’t seasonal; therefore, they can’t utilize H-2A, and that’s something the dairy industry is pushing to change."

Donald Grady, the senior director of legislative affairs at the International Dairy Foods Association, views the H-2A program as something that can be modified to help dairies and off-site milk processing plants. He told Morgan, "We are looking to be able to expand the H-2A program so that dairy operations on-farm and in the plant can have another tool in their toolbox to meet their labor needs."

Despite the recent I-9 audit spike, "leaders within the dairy industry say for the first time in nearly two decades, there does seem to be momentum for changes to the H-2A program and address the pain points with the current immigration system," Morgan adds. The CEO of the Idaho Dairymen’s Association, Rick Naerebout, told Morgan, "We’ve not had this kind of traction with an administration ever on this issue. . . but we’re cautiously optimistic here in Idaho." 

Morgan adds, "Naerebout says after 20-plus years, he thinks agriculture finally has a legitimate chance at solving a problem that’s been plaguing the industry. And that solution needs to not only come from the White House, but the long-term fix needs to be addressed by Congress."

Immigrant farm workers from Mexico once had a clear path to work in the U.S. from the 1940s to the 1960s

A look back at American history reveals a significantly different perspective on Mexican immigrants coming to the United States to fill labor shortages. Beginning in the 1940s and stretching into the mid-1960s, the U.S. recruited thousands of Mexican immigrants to work on U.S. farms.

In Texas, the National Historic Landmark "Socorro’s Rio Vista Farm" operated as the "Rio Vista Bracero Reception Center," which was a designated point of entry for thousands of Mexican workers who entered the U.S. as "part of a temporary labor program," reports Marianne Dhenin for Offrange. "The arriving Mexican workers were known as braceros from the Spanish word for arm, brazo, roughly translating to 'one who swings his arms.'"

Mexican farm worker recruits were able to enter the U.S. by signing up for the Bracero Program. "The program was designed to recruit skilled agricultural laborers from Mexico to mitigate labor shortages in the United States resulting from American farm workers enlisting during World War II and, later, the Korean War," Dhenin explains. During World War II, the U.S. government incarcerated thousands of American Japanese farm workers, which increased the need for Mexican labor.

Workers who wanted to join the Bracero Program "applied at intake stations across Mexico," Dhenin writes. These men "made significant sacrifices in pursuit of economic opportunities in the U.S. Many hoped that higher wages across the border would allow them to provide for those they left behind."

Becoming a Bracero wasn't as easy as just signing up. Applicants were required to undergo extensive medical and psychological testing in Mexico before "being invited to make the trip northward through Mexico and across the border," Dhenin reports. Braceros were often transported into the U.S. in cargo trains "without seats, windows, or water stops along the way."

During the 1950s and early 1960s, the "barracks on Socorro’s Rio Vista Farm served as dormitories, offices, and a mess hall to house and process the more than 80,000 braceros who passed through each year," Dhenin explains. "It was one of five long-term bracero reception centers in California, Arizona, and Texas. . . . Over the lifespan of the Bracero Program, more than 4.6 million contracts were issued." A total of 30 states participated in the Bracero program.

Trump officials reverse pause in ICE raids targeting farm, service workers

In an abrupt about-face from last week's guidance that paused Immigration and Customs Enforcement raids on farms, restaurants and meatpacking facilities, Trump officials reissued their call for ICE to enter any business where undocumented migrant workers might be found.

"Officials from ICE, including its Homeland Security Investigations division, told agency leaders in a call Monday that agents must continue conducting immigration raids at agricultural businesses, hotels and restaurants," report Carol D. Leonnig, Natalie Allison, Marianne LeVine, and Lauren Kaori Gurley of The Washington Post.

The see-sawing instructions reflect the tough reality of supporting American farmers and service workers all the while pushing ICE to arrest thousands of undocumented workers a day. Leonnig writes, "Some immigration experts say ICE would need to ramp up worksite enforcement to meet the administration’s ambitious arrest quotas. Past raids at meatpacking plants, for instance, have led to hundreds of arrests at once."

Even among President Trump's officials, the two sides pull against each other. "White House Deputy Chief of Staff Stephen Miller said last month that the administration wants ICE to make a minimum of 3,000 arrests a day," the Post reports. "Brooke Rollins, the agriculture secretary, meanwhile was on the opposite side of the issue, stressing to Trump the concerns that those in the farming industry had raised about losing workers."

On Sunday evening, Trump pulled away from his farming and service worker exemption stance and "made a post on his Truth Social account that he said amounted to an order for ICE officials 'to do all in their power to achieve the very important goal of delivering the single largest Mass Deportation Program in History,'" Leonnig adds, "which he said would require them to 'expand efforts to detain and deport Illegal Aliens in America’s largest Cities.'"

On Monday, Tricia McLaughlin, an assistant secretary for DHS, told reporters, “There will be no safe spaces for industries who harbor violent criminals or purposely try to undermine ICE’s effort. Worksite enforcement remains a cornerstone of our efforts to safeguard public safety, national security and economic stability.”

Trump pauses raids on farms, service businesses, but many sweeps continue

Some immigrants who have continued work at farms, restaurants, hotels and meatpacking plants have been swept up during Immigration and Customs Enforcement raids, report Ted Hesson and Marisa Taylor of Reuters. A senior Trump official familiar with the situation said President Donald Trump "was not aware of the extent of the enforcement push and 'once it hit him, he pulled it back.'"

"Trump's administration has directed immigration officials to largely pause raids," Hesson and Taylor write. "The order to scale back came from Trump himself … and appears to rein in a late-May demand by top White House aide Stephen Miller for more aggressive sweeps."

Last week's instructions limiting raids "still allows for investigations into serious crimes such as human trafficking," Reuters reports. Democrats called on the White House to pull back on ICE's "aggressive tactics. … Some Republican lawmakers have called on the administration to focus on criminal offenders."

Most American agriculture, including dairy and farm animal care, is supported by migrant workers. Hesson and Taylor add, "U.S. farm industry groups have long wanted Trump to spare their sector from mass deportations, which could upend a food supply chain dependent on immigrants."

The United Farm Workers union remains "skeptical the new directive will help workers without legal status," Reuters reports. "The group said it had calls from members about immigration arrests even after the new directive was issued."

On Friday, UFW issued a stern response to Trump's Thursday order to pause farm raids: "Many companies stayed closed today due to the presence of roving federal agents, especially Border Patrol. … As long as Border Patrol and ICE are allowed to sweep through farm worker communities making chaotic arrests … they are still hunting down farm workers."

Farmers worry about labor shortages as migrants hide from threats, deportation confusion

Migrant farm workers across rural northern New York are reportedly hiding to avoid being picked up, harassed and possibly shipped out of the U.S. by immigration police. American farmers, who often rely on migrant workers to keep their farms profitable, are in an uncomfortable spot. Many voted for Trump but now "feel anxious about the prospect of losing a crucial labor force," reports Anan Ley of The New York Times. 

For migrant workers, hiding is one of the few ways to avoid "what they describe as cruel and chaotic deportation efforts," Ley explains. "In rural New York, some immigrants have been briefly detained and then released, while others with legal papers languish in custody, leaving many confused about who is being forced out of the country and who gets to remain."

If immigration police continue to round up and deport undocumented farm workers, farmers say they will be in a bind. David Fisher, the president of the New York Farm Bureau, a nonprofit industry group, told Ley, "Local sources of labor are simply not available in most cases."

Regardless of the national tension surrounding immigration, undocumented workers fill many U.S. agriculture jobs. "About 42% of farm workers are not legally authorized to work in the country," Ley reports. "In New York State, experts at Cornell University estimated in 2019 that about half of all farm workers were undocumented."

The loss of migrant workers could alter how much of a product a state can produce and ship nationwide. For New York, that means apples. Ley writes, "It is famous for producing more apples than any other state except for Washington — supplying the nation with one of its most-consumed fruits."

Farmers like Robert J. Colby, who runs Colby Homestead Farms just outside the small town of Spencerport, N.Y., advocate for a quick, no-nonsense approach to immigration. He told Ley, "The Congress and Senate [need] to get to work and get an immigration program together . . . . We should be able to vet people’s backgrounds and process them within six months in order for them to be able to come and become citizens."

A whirlwind of policy changes and funding cuts have left rural America on shaky ground: 'Billions are at stake.'

As USDA funds are frozen, U.S. farmers face uncertainty
and possible big financial losses. (Adobe Stock photo)

A whirlwind of policy changes from the Trump Administration has left many people in rural America unprepared to navigate agricultural spending cuts that target farming income and investments.

"Billions of dollars in funding are at stake," report Linda Qiu and Julie Creswell of The New York Times. "One executive order targets. . . money for farmers to conserve soil and water and to complete energy projects. Other directives touch on grants to states and producers. Another temporarily left hundreds of millions of dollars worth of food and supplies sitting in ports and has stopped future purchases of grains and goods."

The loss of income and promised funds from the Department of Agriculture puts farmers and farming communities in a "potentially precarious position," the Times reports. "Even as courts have halted many of the orders, rural communities are reeling from the effects, setting off confusion and panic among one of President Trump’s core constituencies."

Once inaugurated, Trump "ordered an indefinite pause on funding provided by the Inflation Reduction Act. . . . Though a federal judge ordered the Trump administration to unfreeze the funds, it is unclear when and whether it will follow suit," Qiu and Creswell explain."Asked if it would release the money, the USDA did not directly respond, saying only that it had ordered 'a comprehensive review' of its contracts, work and personnel.'"

When farmer pocketbooks took a hit from Trump's first-term tariff wars, the administration tapped the USDA's Commodity Credit Corporation and sent checks to farmers to cover losses. That isn't happening now. "Trump has also paused payments made by the CCC," Qiu and Creswell add. "It is unclear how much of the funding has been frozen."

When U.S. farmers overwhelmingly voted for Trump, it's unlikely they thought his policy changes could force some farms into bankruptcy -- but that could happen. The Times reports, "If funds remain frozen, that could affect more than 25,000 conservation contracts worth $1.8 billion funded by the climate change law, potentially involving thousands of farmers nationwide."

Since the Paleolithic era, honey bees pollinated apple trees and humans picked the apples. That's about to change.

Human apple harvesters must scale ladders, fend off bugs, balance on branches and twist stretchy stems to get the job done. For farmers, hiring experienced apple pickers is difficult and expensive, which is why several "universities and startups are developing specialized robots for each stage of apple production," reports Jackie Snow of The Wall Street Journal. The bots will handle everything from "pollinating the trees to fertilizing them, pruning them and harvesting the fruit."

In areas where there aren't enough honey bees to pollinate apple blossoms, "researchers have developed robotic pollinators," Snow explains. Cameras help robots find apple blossoms, and then "a mechanical arm moves in close and releases a precise burst of pollen through a nozzle. Early results are promising."

Robots used to fertilize apple orchards base their application on individual tree's needs. Snow writes, "They consider multiple indicators, including trunk diameter, canopy growth patterns and fall leaf-color changes, and use AI models to determine precise nitrogen requirements. . . . Researchers believe precisely targeting individual trees could significantly reduce overall fertilizer."

Researchers are working on robots that can also prune. "The robots must evaluate the entire structure of each tree, analyzing branch length, angles, thickness and spacing to determine which cuts will promote ideal growth patterns."

To harvest apples, robots need to be gentle and nimble. "Researchers at Washington State are testing inexpensive, fabric-based robots that have three silicone fingers that close around apples," Snow explains. So far, their research has been in a lab "with fake trees and fruit. . . The system will face its first orchard trials during the next harvest season, in the fall."

Opinion: New administration can support farmers and improve rural America's economies with four 'key steps'

John Bode

Some American farmers and farm workers voted for President Donald Trump, and some didn't, but most are counting on support from the new administration.

In his opinion for AgriPulse, John Bode describes how agribusiness workers are "eager to pursue a more prosperous rural America." He outlines four "key steps" the new administration could draw upon, which he believes would support economic growth and development in many parts of rural America.

Removing limiting regulations is the first step. Bode explains, "Deregulation does not mean elimination of regulation. Regulations provide such essential assurances as product safety and environmental protection. But a stable, rational regulatory environment should also be friendly to economic growth."

Policy that supports U.S. electrical grid integrity and other energy needs is vital. "When Trump left office four years ago, the U.S. electric grid had an overall capacity that substantially exceeded peak demand," Bode adds. "The Federal Energy Regulatory Commission tripled its five-year forecast for peak electric demand. . . .Without bold policy action, America will likely experience rolling blackouts in the next five years. A reliable energy infrastructure is fundamental to economic growth."

Continuing tax cuts would help the American public, businesses and farmers. "Since the Tax Cuts and Jobs Act of 2017 was signed into law, the American economy has had access to robust pro-growth tax policy, " Bode writes. "But many of the provisions that have helped boost business and put more money in the pockets of American workers are set to expire at the end of 2025."

Advancing American trade policy is vital to rural growth. Bode explains, "I believe [the new administration] can achieve alignment with Canada and Mexico so the U.S.-Mexico-Canada Agreement may be refreshed to form a powerful economic platform to compete with China and other non-market economies. We should look past the dramatic tactics and focus on a strategy that advances American competitiveness."

John Bode is president and CEO of the Corn Refiners Association, the trade association representing the corn milling industry, and he chairs the Agricultural Policy Advisory Committee, which advises the Department of Agriculture and U.S. Trade Representative on trade policy.

Driverless tractors are already operating on some U.S. farms. Automation offers benefits, but farm workers worry.

The harvest is plentiful and the workers are robots. That's the plan for some U.S. farms. "A growing number of companies are bringing automation to agriculture. It could ease the sector’s deepening labor shortage, help farmers manage costs, and protect workers from extreme heat," report Melina Walling of The Associated Press and journalist Ayurella Horn-Muller. "Automation could also improve yields by bringing greater accuracy to planting, harvesting, and farm management."

Florida farmer Jeremy Ford was tired of wasting water and using fossil fuel-run equipment to care for his crops, so he turned to an automated underground system, "that uses a solar-powered pump to periodically saturate the roots of his crops, saving 'thousands of gallons of water,'" Walling and Horn-Muller explain. "Although they may be more costly upfront, he sees such climate-friendly investments as a necessary expense — and more affordable than expanding his workforce of two."

What about automated harvesting? "On some farms, driverless tractors churn through acres of corn, soybeans, lettuce and more. Such equipment is expensive, and requires mastering new tools, but row crops are fairly easy to automate," AP reports. South Dakota farmer Frank James along with his family members, "swear by tractor 'autosteer,' an automated system that communicates with a satellite to help keep the machine on track. . . [but] requires human oversight to work as it should."

While some agriculture stakeholders have pushed back against automation, some farmers look to the technology's potential to increase profitability and decrease business headaches. Walling and Horn-Muller report, "Will Brigham, a dairy and maple farmer in Vermont, sees such tools as solutions to the nation’s agricultural workforce shortage. Since 2021, Brigham’s family farm has been using Farmblox, an AI-powered farm monitoring and management system that helps them get ahead of issues like leaks in tubing used in maple production."

Robotic farm tools may make caring for crops during extreme heat more efficient without putting human workers at risk. "Extreme heat, drought and intense rainfall have made labor-intensive corn detasseling even harder," Walling and Horn-Muller write. 

Even with its benefits, automated farming may affect farm worker employment. "Automation can be a 'tactic, like a strategy, for bosses, so people are afraid and won’t demand their rights,' said Luis Jimenez, a New York dairy worker. Robots, after all, 'are machines that don’t ask for anything,' he added. 'We don’t want to be replaced by machines.'"

As dairy cows enter the U.S. food chain, many will be tested for the bird flu virus, aka, H5N1

Dairy cows will be the focus of new slaughterhouse
testing for bird flu by the USDA. (Adobe Stock photo)

The Department of Agriculture will boost its bird flu or H5N1 response to U.S. dairy and beef livestock infections by "expanding bird-flu testing of beef entering the food supply," reports Leah Douglas of Reuters. In May, the agency tested 109 beef samples from "dairy cows sent to slaughter and found bird flu virus particles in one cow's tissue sample. Older dairy cattle are often slaughtered for ground beef."

Dairy cows will be the focus of most slaughterhouse testing. "Nearly 200 herds in 13 U.S. states have contracted bird flu since March after the virus jumped from wild birds to cows, according to USDA data," Douglas explains. "Eric Deeble, deputy undersecretary for marketing and regulatory programs, said the USDA is confident with the current level of bird-flu testing conducted by the nation's dairy farmers."

Meanwhile, dairy operators and workers are at increased risk of contracting H5N1. To date, 13 poultry and dairy workers have contracted bird flu since April, and workers who might be exposed to infected animals need to wear personal protective equipment.

To further address the virus' presence across the U.S., the Food and Drug Administration is "talking with states about the plausibility of additional nationwide raw milk testing," Douglas reports. The Centers for Disease Control and Prevention is "working on expanding its surveillance wastewater testing to H5 viruses in advance of the fall and winter flu season."

According to the USDA, U.S. beef and dairy products are safe to consume.

Dairy farmers and livestock veterinarians face the stresses of bird flu virus' surprising transmission to cattle

flu in cattle has increased tensions. (Adobe Stock photo)

Razor-thin profit margins and see-saw market prices already make the life of U.S. dairy farmers tough. Farmers must now contend with the unknowns of an evolving bird flu virus, which could infect herds and farm workers. "Avian influenza has hit dairy farms in at least 12 states after being confirmed in March to have jumped to cattle, reports Victor Stefanescu of The Wall Street Journal. "The malady, which can curb cows’ milk production and upend dairy farms’ operations, is the latest curveball for an industry that has grappled with low-profit margins, drought and shifting consumer tastes."

This version of bird flu, or H5N1, has been reported in 136 herds nationwide. The highly contagious virus is a stressful wildcard for dairy farmers because it slows milk production and some cows will not survive the infection. Stefanescu explains, "The virus has reached at least 26 herds in Idaho, where affected farms are losing up to a fifth of their milk production for three to four weeks. It is costing the average producer in the state $10,000 a day in lost revenue, said Idaho Dairymen’s Association Chief Executive Rick Naerebout."

One way dairy farmers are working to fight the introduction or spread of H5N1 is through biosecurity measures. "In Michigan, third-generation dairy farmer Ashley Kennedy is trying to boost biosecurity by limiting visitors’ access to her cows and logging the people who enter and exit the farm, as the state requires," Stefanescu writes. Some farmers in Wisconsin are deploying drones to chase away wild birds that may carry the virus.

Farmers aren't alone in facing additional stress brought on by bird flu's surprising transmission to cattle. Livestock veterinarians are also affected. In April when "the federal government began requiring some cows to be tested for a strain of avian flu before their herds could be moved across state lines, it seemed like an obvious step to try to track and slow the virus that had started spreading among U.S. dairy cattle," reports Andrew Joseph for STAT. "But Joe Armstrong, a veterinarian at the University of Minnesota extension school, feared the Department of Agriculture rule could lead to potential problems for his colleagues."

In practice, the USDA's rule puts veterinarians in the crosshairs between what the government demands and what the livestock owners are willing to do. Armstrong told Joseph: "There will be clients lost over this situation. That amount of stress and pressure from two directions — USDA from the top, clients from the other side — puts practicing veterinarians in a very stressful day-to-day.”

It's not an easy position for veterinarians, but their role in tempering the spread of H5N1 is vitally important. Joseph adds, "Since the outbreak in cattle was discovered earlier this year — by veterinarians themselves, — dairy veterinarians have been on the frontlines of the response. They’re testing cows. They’re teaming with farmers and dairy workers to prevent additional infections, both bovine and human. They’re using their on-the-ground experience to trace how the virus is transmitting."

Dairy farmers have been slow to allow -- or have even refused -- H5N1 testing on their farms. Keith Poulsen, a veterinarian who now spends most of his time running the Wisconsin Veterinary Diagnostic Laboratory, told Joseph, "It makes it really challenging to be that veterinarian and say, I know there’s flu on this farm, but the owner won’t approve testing. That makes a pretty big ethical dilemma for veterinarians.”

Quick hits: The resilient Mississippi River; pizza and sunscreen's shared ingredient; food costs; a new ice cream

In the fall of 2022, the Mississippi River was drying up and commodity shipping was an expensive struggle. "Dropping water levels in the Mississippi River have caused shipping costs to rise just as harvest season approaches for many Midwestern soybean and corn farmers," reported Keely Brewer in a story for the Daily Memphian." By 2023, things had not improved. "Historic low flows turned the Mississippi River into a construction area in 2023 as the U.S. Army Corps of Engineers dredged huge quantities of sand to keep the channel open for barge traffic," reports Chloe Johnson of the Minneapolis Star Tribune. Earlier this year, "The U.S. Army Corps of Engineers announced that the drought that plagued the Mississippi River basin since 2022 was officially over." Despite this glorious improvement, here's how to keep caring for the mighty Mississippi. 

On a dairy farm where not everyone speaks the same language, confusion and frustration can impede good animal care. "Great animal welfare is only achievable when a dairy has a strong employee welfare focus," writes Dr. Kaitlyn Lutz for Lancaster Farming. "Consider these practical ideas to improve management as a step toward a culture of care for your employees and cows: 1. Use WhatsApp -- Your Hispanic workers are using it. If you're not, you miss a huge opportunity to connect. 2. Connect over family -- Ask employees about their families. Language barrier? Check out the PONS Translate app's conversation mode. Or, share pictures. 3. Build trust -- Trust is built through small and consistent actions over time."

Titanium dioxide is found in sunscreen and pizza.

Adding sunscreen to your frozen pizza sounds disgusting. And yet, "If you have heard of titanium dioxide at all, you probably know it as an ingredient in sunscreen. But it is also used in lots of foods, from pizza and salsa to frosting and candy—and now, there is growing concern about the potential health risks of eating it," reports Andrea Petersen of The Wall Street Journal. "Some research, mainly in animals, has suggested that eating it might be linked to immune system problems, inflammation and DNA damage that could lead to cancer. . . . The European Union has banned titanium dioxide in food since 2022."

U.S. families continue to balance needs with costs.

U.S. consumers continue to grapple with high grocery prices, which drain their budgets and leave some families struggling to make ends meet. "Results from the most recent wave of the Gardner Food and Agricultural Policy Survey demonstrate that consumers perceive inflation and high food prices to be persistent problems," reports Brenna Ellison for Farmdocdaily. "Consistent with this, a recent Gallup poll found that 41% of households identified inflation as the most important financial problem they are currently facing. . . . Some retailers like Target, Walmart, Amazon, and Walgreens have announced they will be cutting prices on thousands of items."

Crop insurance helps provide income stability for food and animal producers who must make a living despite unpredictable weather, hungry pests and insidious weeds. This year marks the biggest acreage for U.S. crop insurance coverage. "Farmers and ranchers bought crop insurance policies on more than 500 million acres of land last year, the largest amount ever, driven by the surging popularity of forage policies," reports Successful Farming. "Overall enrollment in crop insurance was up 85% in the seven years from 2016, according to Department of Agriculture data."

A creamy, cool, delicious ice cream cone is one of summer's simple delights -- until your dip starts dripping and your cone starts crumpling. Then the slurp and smear battle ensues. Could there be a less-melty way? "Cameron Wicks, a student at the University of Wisconsin, is working on a new technology that adds naturally occurring compounds [polyphenols] to ice cream," reports Elise Mahon for University of Wisconsin News. Wicks told Mahon, "We learned that adding polyphenols to ice cream can create a product that holds its shape for over four hours at room temperature. That's pretty close to a no-melt ice cream."

The U.S. and Europe are considering bird flu vaccinations for high-risk citizens; preparations are underway

As avian flu travels around the globe, infecting birds, wildlife, cows and people, some countries are considering vaccines for citizens in high-risk professions. Julie Steenhuysen and Jennifer Rigby of Reuters report, "The United States and Europe are taking steps to acquire or manufacture H5N1 bird flu vaccines that could be used to protect at-risk poultry and dairy workers, veterinarians and lab technicians . . .  moves influenza experts say could curb the threat of a pandemic."

The U.S. is "moving bulk vaccine from CSL Seqirus that closely matches the current virus into finished shots that could provide 4.8 million doses of vaccine," Steenhuysen and Rigby write. "European health officials told Reuters they were in talks to acquire CSL's pre-pandemic vaccine." Canada and the United Kingdom are also meeting with their vaccine suppliers to plan for pre-pandemic vaccines.

The newest strain of bird flu, also called H5N1, belonging to clade 2.3.4.4b, was detected in late 2020 and "caused unprecedented numbers of deaths among wild birds and domestic poultry and has begun infecting many mammal species," Reuters reports. "In March, U.S. officials reported the first outbreak of the virus in dairy cattle. . . .The Food and Drug Administration has estimated that 20% of the U.S. milk supply shows signs of the virus, indicating a wider spread is likely."

As more humans are exposed to H5N1, the chance that it may mutate and be able to spread more aggressively in human populations increases. Matthew Miller, co-director of the Canadian Pandemic Preparedness Hub at McMaster University, told Reuters, "All of our efforts need to be focused on preventing those events from happening. Once we have widespread human infections, we're in big trouble."

Reuters reports. "Dr. Richard Webby, a St. Jude Children's Research Hospital virologist who studies flu in animals and birds for the World Health Organization, said the situation in dairy cattle merits vaccine use." He told Reuters, "If we look at the exposure levels that some of these farmers are getting, it's high."

Many deaths at Wisconsin small dairy farms could be prevented; OSHA could use its authority to dig deeper

farm dangers. (Photo via ProPublica)

Deaths on small dairy farms in Wisconsin often don't lead to safety inspections, perhaps leaving farm workers unprotected from preventable dangers. In the case of many deaths over the last decade, the Office of Safety and Health Administration never opens a case, citing a lack of authority; however, had the agency probed further, it could have done more," report Maryam Jameel and Melissa Sanchez of ProPublica. "How OSHA interprets and applies its definition of a "temporary labor camp" — and whether it should consider dairy workers temporary when farms produce milk year-round — has significant implications for the safety of thousands of workers in one of America's most dangerous industries."

ProPublica reports on three specific deaths of immigrant dairy workers that may have resulted from a lack of safety or training, but in each case, OSHA inspectors "went to the farms [and] left within an hour — without conducting investigations into the deaths. . . .The inspectors concluded they couldn't investigate because OSHA is banned from enforcing safety laws on farms with fewer than 11 workers unless they have employer-provided housing known as a 'temporary labor camp.'"

A broader look at dairy farm deaths raises more questions. "Since 2009, at least 17 workers, most of them immigrants, have died on Wisconsin dairy farms. Twelve of the deaths happened on farms with fewer than 11 workers. OSHA did not inspect eight of those 12, each time citing the small farms' exemption," Jameel and Sanchez write. "Records reviewed by ProPublica and interviews show that the agency may have more power to open an investigation into these farms than even its own leaders seem to be aware of."

In all three deaths ProPublica examined, how the inspectors so quickly came to their conclusions seems unclear. ProPublica reports, "Had the inspectors taken a slightly closer look, they might have learned that the farmers had readily talked with law enforcement officials about providing housing for their immigrant workers. . . . And if the inspectors had read OSHA's own files, they would have known that the agency has repeatedly, though inconsistently, inspected small farms after concluding a housing arrangement was a temporary labor camp."

Lola Loustaunau, an assistant professor at the University of Wisconsin-Madison School for Workers, told ProPublica that 'it would really open the door for a lot of protections for workers' if OSHA consistently inspected small dairy farms that provide housing to immigrant workers."

Farm safety quick hits: Create a rescue plan; manure pit accidents; women in ag; ATV safety; mental health first aid

Farming comes with a distinct set of dangers and demands. Sound planning, accident prevention and know-how can improve measures to keep farm workers safe, reports Lisa Foust Prater of Successful Farming. Prater also looks at the medical needs of women in agriculture and mental health for everyone who works the land.

Have a rescue plan before entering a silo, grain bin, manure pit or other confined space. The Department of Agriculture recommends identifying confined spaces on your farm and taking steps to prevent accidental entry. "Workers who do enter must receive specific training and have a permit to enter."

Dirty and deadly, take extra care around manure pits.

Manure pits are dangerous. "Working in a manure pit is one of the dirtiest jobs on the farm, and it's also one of the deadliest. The majority of people who are overcome by the gases in a storage pit or lagoon do not live to tell the tale. . . . The most common task leading up to these injuries or fatalities in 2022 was performing maintenance tasks in or around manure storage structures, including pump repairs. This is true with all cases documented since 1975."

Whether you're delivering cookies to the back forty or hauling feed, ATVs are speedy, farm-friendly vehicles. Curt Porterfield, health and safety training coordinator at Virginia Tech, offers these tips to keep ATV riding safe: Recognize that ATVs can be deadly, the common hazards associated with their use, and your skill levels. Evaluate your equipment, terrain, environment, and load. Control and maintain your ATV properly. . . .and control your ride by driving safely.

Almost a third of all American farmers are women.

The number of women in agriculture has increased, but information studies have yet to keep pace with the change. "Despite the fact that 31% of all American farmers are women, health and safety education for the agricultural population is most often aimed at men. . . . Women on the farm fill more roles than ever before – or are at least being publicly recognized for filling these roles – including primary operator, mother, wife, ag implement salesperson, and large animal veterinarian, to name a few. Specific areas of risk include heart disease, diabetes, breast cancer, broken bones and chronic pain."

Farming offers many benefits, but mental health often takes a back seat to getting the work done, which can ultimately cause a breakdown. "Becoming trained in mental health first aid allows you to stand in the gap of a crisis until professional help arrives. . . . If the emergency is someone having an anxiety attack, dealing with an opioid addiction, or contemplating suicide, having someone available who knows what to do can mean the difference between life and death."
