Toronto (AP) - The manufacturer of pet food blamed for causing kidney failure in cats and dogs says the company will take responsibility for veterinary expenses incurred as a result of the food.
Menu Foods expanded its recall to all 95 brands of its "cuts and gravy" style food today.
Company president Paul Henderson says he doesn't believe there's been any tampering because the food came from two plants, one in Emporia, Kan. and one in New Jersey. He says the company is testing all ingredients that go into the food.
ALBANY, New York (AP) - Rat poison has been found in pet food blamed for the deaths of at least 16 cats and dogs, a spokeswoman for the State Department of Agriculture and Markets said Friday.
The toxin was identified as aminopterin, state Agriculture Commissioner Patrick Hooker said in a statement. Aminopterin is used to kill rats in some countries but is not registered for that use in the United States, according to the Environmental Protection Agency.
The officials did not say how they believed it got into the pet food. (Watch why devastated pet owners are suing Video)
The substance was found at a level of at least 40 parts per million in tested cat food samples, according to Donald Smith, dean of Cornell University's College of Veterinary Medicine.
Aminopterin, also used as a cancer drug, is highly toxic in high doses. It inhibits the growth of malignant cells and suppresses the immune system.
The Food and Drug Administration has said the investigation was focusing on wheat gluten in the food. Wheat gluten itself would not cause kidney failure, but the common ingredient could have been contaminated by heavy metals or mold toxins, the FDA said.
State and FBI officials said they knew of no criminal investigations in the case.
The pet deaths led to a recall of 60 million cans and pouches of pet food produced by Menu Foods and sold throughout North America under 95 brand names. There have been several reports of kidney failure in pets that ate the recalled brands, and the company has confirmed the deaths of 15 cats and one dog.
Menu Foods last week recalled "cuts and gravy" style dog and cat food. The recall sparked concern among pet owners across North America. It includes food sold under store brands carried by Wal-Mart, Kroger, Safeway and other large retailers, as well as private labels such as Iams, Nutro and Eukanuba.
Menu Foods is majority owned by Menu Foods Income Fund of Streetsville. The company also makes foods for zoo cats, but those products are unaffected by the recall.
The company's chief executive and president said Menu Foods delayed announcing the recall until it could confirm that the animals had eaten its product before dying.
Two earlier complaints from consumers whose cats had died involved animals that lived outside or had access to a garage, which left open the possibility they had been poisoned by something other than contaminated food, he said.
Menu Foods planned a media teleconference for later Friday, a spokesman said.
A spokesman for New York Attorney General Andrew Cuomo said he was not aware of any criminal investigation involving the tainted food. FBI spokesman Paul Holstein in Albany said Friday he was not aware of any FBI involvement in the case.
"I don't know where we'll go from here," he said.
