AVMA reports on contaminants in last year's pet food recall
The December 1, 2007 Journal of the American Veterinary Medical Association (JAVMA) included an article entitled "Researchers examine contaminants in food, deaths of pets." The article discusses new revelations about last year's massive pet food recall.
Some of the researchers' findings are outlined below. Before you read them, I should warn you: what they discovered might not make you happy.
Here's how it looks to me. Note that what I am about to say is speculation, not proven fact.
The manufacturer of the wheat flour involved in the recall may have purposefully added melamine in order to obtain a higher price for the product. The manufacturer used low-quality melamine that was contaminated with cyanuric acid.
The combination of melamine and cyanuric acid caused kidney failure in some of the pets that ate contaminated food. If this hypothesis is true, it is scandalous indeed.
