The U.S. Environmental Protection Agency finalizes new rules to protect farmworkers from pesticides.

The agency estimates that pesticide exposure poisons between 10,000 and 20,000 farmworkers each year. Last updated in 1992, the new standards require annual pesticide risk training and prohibit children under 18 from handling the chemicals. Still, some say they don't go far enough to protect those who put food on our tables. NPR
