Your Turkey May Have Feasted on ... Arsenic It's a common ingredient in turkey feed By Nick McMaster, Newser Staff Posted Nov 25, 2010 11:19 AM CST 4 comments Comments Turk, a Heritage Turkey, roams the Louden Farm near Princeton, Kan., Wednesday, Nov. 24, 2010.

(AP Photo/Orlin Wagner) (Newser) – Here's a fun fact to throw around the Thanksgiving table: Lots of turkey farms use arsenic in their feed. Yes, that arsenic, the deadly poison, which can control stomach bugs in turkeys and fatten them up, explains NPR's Shots health blog. It can also show up in the turkey meat on the table in trace amounts. Reason for worry? The FDA says no—based on standards developed in the 1950s. "But since then, there's been an enormous amount of research on the human health effects from arsenic exposure," says a Johns Hopkins expert on the subject. That includes an EPA discovery that arsenic's cancer-causing potential is 17 times more potent than previously believed. Therefore, "it seems irresponsible to rely on FDA's tolerances to protect public health," he says. Bon appetit.
