“We were kind of floored,” said Keeve E. Nachman, a co-author of both studies and a scientist at the Johns Hopkins University Center for a Livable Future. “It’s unbelievable what we found.”       
He said that the researchers had intended to test only for antibiotics.
But assays for other chemicals and pharmaceuticals didn’t cost extra, so researchers asked for those results as well.       
“We haven’t found anything that is an immediate health concern,” Nachman added. “But it makes me question how comfortable we are feeding a number of these things to animals that we’re eating. It bewilders me.”       
Likewise, I grew up on a farm, and thought I knew what to expect in my food. But Benadryl? Arsenic? These studies don’t mean that you should dump the contents of your refrigerator, but they do raise serious questions about the food we eat and how we should shop.
