Today, the Center for Food Safety (CFS) and the Institute for Agriculture and Trade Policy (IATP), filed a petition with the Food and Drug Administration (FDA) calling for the immediate withdrawal of approvals for all animal drug applications for arsenic-containing compounds used in animal feed. Arsenic is used to promote faster weight gain on less feed and creating the appearance of a healthy meat color in chickens, turkeys and hogs. Test results have revealed detectable levels in the meat exposing consumers to another pathway for arsenic exposure The petition was supported by a coalition of food and farm groups.
