More on the recent pet food recall...
Scientists with the Food and Drug Administration have linked a chemical to the illness and deaths of cats eating tainted food and raised for the first time the possibility that dry pet food may have been affected as well as wet food.
F.D.A. officials said at a news conference today that they have
linked the chemical melamine, which they said is used as a fertilizer
in Asia, to the kidneys of the affected cats. Thousands of owners of
both cats and dogs who feed their pets wet or dry food have complained
that their pets have become ill, but the F.D.A. has not yet determined
if those illnesses are linked to pet food.
The agency has
recalled a batch of contaminated Chinese wheat gluten that was sent to
many pet food manufacturers, including one that makes dry dog food.
But
they said they do not know yet if the contaminated wheat gluten has
been used to make pet food. And the F.D.A.’s finding was also
immediately disputed by the New York State Food Laboratory, the testing
facility that announced last Friday it had identified Aminopterin, a
rat poison, in samples of tainted cat food.
Because the F.D.A.
identified melamine crystals in the kidneys of affected cats, the
agency is presuming the illnesses are related to the chemical, said Dr.
Stephen F. Sundlof, director of the F.D.A.’s Center for Veterinary
Medicine.
F.D.A officials have not yet released the name of the
dry pet food company that received the contaminated wheat gluten,
saying it was not clear if any of that gluten had yet been made into
dog food.
“We are in the plant right now,” said Michael Rogers,
director of the division of field investigations in the office of
regulatory affairs for the F.D.A. “At this time, we’re not certain any
dry food was made with that wheat gluten. As soon as we find out what
dry food, if any, was manufactured, we will announce it publicly.”
Jessica
A Chittenden, a spokeswoman for the New York State Department of
Agriculture and Markets, said “We don’t think this is the final
conclusion. Melamine is not a known toxin. There’s not enough data to
show that it is toxic to cats.”
She added: “We are confident we
found Aminopterin, and it makes sense with the pathology.” She also
said another laboratory, Animal Health Laboratory at the University of
Guelph in Canada, had confirmed the presence of Aminopterin in the
samples.
But the F.D.A. said they had been unable to find
Aminopterin in the pet food samples it had tested. Researchers at
Cornell said they were also unable to find any evidence of the rat
poison.
“We believe the laboratories involved in this
investigation should continue to maintain an open forum to definitively
identify the one or more agents that are causing the deaths and
illnesses of cats and dogs so that they do not enter the animal or
human food chain in the future,” said Patrick Hooker, the agricultural
commissioner for the state of New York.
Though Dr. Sundlof said
he was not certain melamine was the chemical causing illness in dogs
and cats, “at this point in the investigation, we are not focusing on
Aminopterin.”
F.D.A. officials announced they had received more
than 8,000 complaints from pet owners with sick pets, but they have not
yet had “the luxury of time” to confirm all of those complaints are
linked to tainted pet food.
Officials did acknowledge, however, that many of the complaints were from owners who only fed their pets dry food.
A complete list of the recalled products along with product codes, descriptions and production dates was posted on Menu Foods' Web site. The company also designated two phone numbers that pet owners could call for information: (866) 463-6738 and (866) 895-2708.
