FDA Withdraws Arsenic-Based Drugs Used for Food Animal Production

November 20, 2013

After a study revealed clear evidence of the effects of arsenic drugs in chicken production, the U.S. Food and Drug Administration (FDA) has withdrawn the approvals of three of four arsenic-based drugs used in food animal production.

According to the study, the use of the three arsenic drugs had increased inorganic arsenic, a known carcinogen in chicken breast meat. The three drugs that were withdrawn are roxarsone, arsanilic acid, and carbarsone. The fourth arsenic drug, nitarsone, will remain on the approval list, as it helps turkeys and chickens develop faster.
