Rat poison found in tainted pet food By MARK JOHNSON, Associated Press Writer

ALBANY, N.Y. - Rat poison was found in the pet food suspected of causing kidney failure that killed at least 16 cats and dogs, but scientists still don't know how it got there, state officials said Friday.
The toxin was identified as aminopterin, which is used to kill rats in some countries, state Agriculture Commissioner Patrick Hooker said.
Aminopterin is not registered for killing rodents in the United States, according to the Environmental Protection Agency, though it is used as a cancer drug. State officials wouldn't speculate on how the toxin got into Menu Foods' now-recalled pet food but said no criminal investigations had been launched.
Scientists at the New York State Animal Health Diagnostic Center at Cornell and at the New York State Food Laboratory tested three cat food samples provided by Menu Foods and found Aminopterin in two of them. Hooker said they would test individual components of the pet food, as well. The early test results were released to give veterinarians a better idea of how to treat sick animals.
"Any amount of this product is too much in food," Hooker said.
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.
In dogs and cats, it can cause kidney failure, according to Donald Smith, dean of Cornell University's College of Veterinary Medicine.
The Food and Drug Administration has said the investigation into the pet deaths was focusing on wheat gluten in the pet food. Wheat gluten itself would not cause kidney failure, but the common ingredient could have been contaminated, the FDA said.
Bob Rosenberg, senior vice president of government affairs for the National Pest Management Association, said he had never heard of the substance before Friday.
"It would make no sense to spray a crop itself with rodenticide," Rosenberg said, though he said grain shippers typically put bait stations around the perimeter of their storage facilities.
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.
The company, already facing lawsuits, planned a media teleconference for later Friday, a spokesman said. It is majority owned by Menu Foods Income Fund of Streetsville.

. The company also designated two phone numbers that pet owners could call for information: (866) 463-6738 and (866) 895-2708.
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.
