Chinese Wheat Gluten Implicated in Pet Deaths Banned

The U.S. is blocking imports of wheat gluten from a company in China, acting after an investigation implicated the contaminated ingredient in the recent pet-food deaths of cats and dogs.

The Food and Drug Administration took action against wheat gluten from Xuzhou Anying Biologic Technology Development Co. in Wangdien, China, after the U.S. recall of nearly 100 brands of pet food made with the chemically contaminated ingredient. The pet food, tainted with the chemical melamine, apparently has resulted in kidney failure in an unknown number of animals.

Wheat gluten from China has been suspected in the outbreak since the first of multiple recalls was announced in mid-March. Even more pet food could be recalled in the next few days, though there probably has been no contamination of human food, FDA officials said Monday.

The FDA reported last week that it had found melamine in samples of the vegetable protein source used in the recalled wet and dry pet foods and treats, as well as in cats that died after eating contaminated food.

"The wheat gluten that is positive for melamine all has come from this manufacturer," Neal Bataller, director of the division of compliance with the FDA's veterinary medicine office, told reporters. Melamine is used in plastics, countertops, glue, fire retardants and other products. Its toxicity to dogs and cats is unknown, but it is not allowed in food in any quantity.

Geng Xiujuan, Xuzhou Anying's sales manager, said the company was aware of the FDA's import alert and was looking into it. However, Geng said the company had not manufactured the wheat gluten but had instead bought it from companies in neighboring provinces.

Investigators are still trying to track down the source of the contamination and how it entered the food stream for pets.

For those who aren't quite sure what products have been recalled thus far, here's what claims to be a comprehensive listing. That list may yet expand further.

There's another recall of pet food that is unrelated to the one that felled so many pets in the past couple of weeks. This recall relates to potential salmonella contamination.
