It has just been reported that aminopterin, an ingredient found in rat poison, has been identified in the recalled pet foods manufactured by Menu Foods a week ago.

Illegal for use in the United States, this toxic substance is believed to have contaminated wheat or wheat gluten products that were imported from China.

Pet food is regulated by the U.S. Food and Drug Administration (FDA), which is now conducting an investigation into the extent and cause of the problems traced to products originating from the Menu Foods manufacturing plants in the U.S. and Canada. Complaints can be submitted to your State FDA Consumer Complaint Representative.
