This has been discussed on here before, and it was basically found to never be true. This one lab never came forward and produced the actual report or showed any evidence to back up their claims.
[i:nrm01hpo]Itchmo called Canidae this afternoon to inquire if they had received the lab results from their testing. They received the test results yesterday. A Canidae spokesperson released this statement to us:
In view of recent reports that have been circulating that products of major pet food manufacturers contain acetaminophen, Canidae wants our customers to know that we have tested our products. The results confirm what we at Canidae already know: we do not put acetaminophen in our products in any way, shape or form. Independent laboratory results found no detectable acetaminophen at 1 part per million.
One unconfirmed report by one laboratory appears to have given rise to the postings and rumors about our products. That same laboratory has also claimed acetaminophen contamination in other manufacturers
