Menu Foods Recall Update

Recalled pet foods contained a chemical used to make plastics, but government tests failed to confirm the presence of rat poison, federal officials said Friday.

The Food and Drug Administration said it found melamine in samples of the Menu Foods pet food, as well as in wheat gluten used as an ingredient.

Cornell University scientists also have found the chemical, also used as a fertilizer, in the urine of sick cats, as well as in the kidney of one cat that died after eating the company's wet food.
