Pet deaths expected to rise despite recall: FDA

By Alexandria Sage

LOS ANGELES (Reuters) - U.S. health officials said on Monday they expected the number of pet deaths to increase as they probe the cause of tainted pet food that has already killed at least 10 animals through kidney failure.

Wheat gluten was the likely cause of contamination that prompted a recall last Friday of more than 50 "cuts-and-gravy"-style labels of wet pet food made by Canada-based Menu Foods.

The recalled products represent 1 percent of all the pet food sold in the United States, officials with the U.S. Food and Drug Administration said.

Dr. Stephen Sundlof, director of the FDA Center for Veterinary Medicine, told reporters he expected more pet deaths as the investigation continues.

He said that wheat gluten was the likely cause of contamination, adding that hypothesis might change as other ingredients are tested.

Menu Foods has said the timing of the complaints coincided with the use of an ingredient from a new supplier. Use of that ingredient, which was not named, has been discontinued, it said.

The FDA said it believes it knows who that supplier was, but has not yet confirmed its name.

"We're trying to find out whether or not that company may have supplied other companies," Sundlof said.
