Texas Agriculture Commissioner Sid Miller in February "announced an emergency state rule change allowing the use of the warfarin-based poison Kaput, which was recently approved by the Environmental Protection Agency to kill wild pigs," Smith writes. The state's feral hogs, which are blamed for eating newborn lambs, uprooting crops and trampling parks and highways, are estimated to cause $50 million in damage per year.
When pigs eat the pesticide, "it kills them slowly, often painfully and turns their innards blue. It’s already wiped out swine herds in Australia, which later banned the product as inhumane," Avi Selk reported in March for The Washington Post.
