![]() "Pets are part of the family structure," Smith told ABC News at the conclusion of the Washington, D.C., press conference. Aminopterin, a derivative of folic acid, is sometimes used as a rodenticide, though such use is banned in the United States and Canada. However, Smith and Stephen Sundlof, the FDA's chief veterinarian, noted at the Washington press conference that neither Cornell nor the FDA could confirm the presence of aminopterin in samples. Smith participated in that press conference because the samples of pet food tested by the Albany laboratory had been supplied by Cornell researchers during an early phase of the investigation. 3, 2006, to March 6, 2007.Īt a press conference in Albany on March 23, researchers at the New York State Agriculture and Markets Food Laboratory reported they had found a toxin called aminopterin in two out of three pet food samples provided by Menu Foods. On March 16, Menu Foods issued a massive recall of 60 million cans and pouches of pet food packaged from Dec. Menu Foods, the pet food maker for 95 top brands of "wet" pet foods, initially contacted Cornell's Animal Health Diagnostic Center to test pet food samples after six cats in one of their food trials died from kidney failure. ![]() He also cited collaborations with other universities and private laboratories, including Advion, in Ithaca. Smith noted that Cornell has been playing a leading role in trying to identify the toxic properties of the contaminated food and in attempting to understand what might be causing the kidney failure. He specifically referred to signs of acute damage to the tubules and the characteristic pattern of cellular inflammation that have been seen in affected kidneys. However, Smith emphasized, Cornell researchers have not been able to match the known toxic effects of melamine with all of the clinical and pathologic signs observed in affected cats and dogs. Veterinarians across the country have reported hundreds of cases of kidney failure in pets.ĭuring the press conference, which was shown on CNN, Smith displayed photographs of the urinary tract crystals from affected animals that have been seen by clinicians and pathologists in many parts of the country, and he also showed a microscopic image of an affected kidney. The deaths of 15 pets nationwide - one dog and 14 cats - have been confirmed by Menu Foods, the pet food maker. ![]() Smith also reported that Cornell had identified melamine in urine of affected cats and in the kidney of one cat that had died after eating the contaminated food. Food and Drug Administration (FDA) March 30 press conference in Washington, D.C., to announce that both Cornell and the FDA had independently identified a contaminant called melamine in samples of recalled pet food and in suspect wheat gluten used in its manufacture. This electron microscope image shows crystals of the type found in the urinary tracts of cats affected by recently discovered pet food contaminants.Ĭornell College of Veterinary Medicine Dean Donald Smith joined a panel of experts at a U.S. ![]()
