Nobody wants explosive diarrhea — and yet the way our federal government has left us unprotected is enough to make one sick. It has also spent hundreds of thousands of dollars to directly lobby against food safety regulations. Last year the administration weakened the nation’s already thin food safety monitoring service, FoodNet, by making it optional to track numerous types of infections — including cyclosporiasis. “We’re really gutting one of the cornerstones of food safety,” epidemiologist Elaine Scallan Walter warned the New York Times last September. The funding losses have left small farmers reeling.
