No Aminopterin in Tissues of Animals Killed by Recalled Pet Food (BlackCat Note: Emphasis Added)
AUBURN, Wash., March 30 /PRNewswire/ — Researchers from Syntrix Biosystems, Inc. and The University of Medicine and Dentistry of New Jersey (UMDNJ) announced today that there was no evidence of Aminopterin in the tissues of animals who had died from consuming food from Menu Foods, the manufacturer of the many brands of dog and cat food that are currently the subject of a nationwide recall.
“We became concerned when Aminopterin was implicated as the toxin in the recent pet food recall. The clinical pattern did not fit the known toxicology of Aminopterin,” said John A. Zebala, M.D., Ph.D. President and CEO of Syntrix Biosystems. “We immediately reached out and offered our expertise to other investigators in the field who had reported finding the compound in food samples.”
Using a highly specific and sensitive test for Aminopterin, investigators at UMDNJ documented that there was no evidence of Aminopterin in the tissues of affected animals. “Aminopterin persists in the liver of animals for months at levels that are readily detected,” said Barton A. Kamen, M.D., Ph.D. Professor of Pediatric Oncology at UMDNJ. “Whatever is causing the renal failure, it is not Aminopterin.” These results are completely consistent with the findings of the FDA, who announced today that they found no evidence of Aminopterin in food samples.
