Pet Food Recall: 2nd Chemical Found

The FDA cannot confirm the presence of aminopterin in the recalled pet foods, but announced today it found a second chemical possibly responsible for kidney failure. Melamine is a chemical used in the manufacturing of plastics, and was found in the affected wet food, in the kidneys of animals, and in the wheat gluten imported from China.

It is not clear exactly which of these chemicals, if any, is causing kidney failure in cats and dogs. The FDA also announced that a maker of dry pet food potentially received a shipment of contaminated wheat gluten. Obviously that referred to Purina and Hills, who expanded the recall to certain Alpo and Science Diet products.

CNN has an update.
