Ever since I received a copy from Evanger’s of their lab report (also posted on the company’s web site), I have been trying to figure out how FDA could possibly determine that there was no duck meat present in their sample of dog food, while Genetic ID – the third-party lab used by Evanger – found duck DNA in the sample that was submitted to them for testing.

My first thought was that there was may have been a significant difference in lab methods used by FDA and Genetic ID. That thought was quashed earlier today, when I ascertained from FDA that the agency used a PCR method – the same type of method as the one used by Genetic ID. Even a slight difference in technique would not be enough to explain a total lack of positive duck meat reaction in FDA’s hands.

I was stymied until I revisited the wording of the FDA warning letter and compared it to the wording of the information released by Evanger.

Here’s the relevant portion of the Evanger statement:

“Our results show that, in fact, Evanger’s brand Super Premium Duck was detected positive for duck…”

And here’s the relevant statement from the FDA warning letter:

“The labeling indicates that Evanger’s Grain-free Duck Pet Food contains duck, but the analytical sample results did not detect the presence of duck in the product.”

A quick review of Evanger’s website brought everything into focus. Super Premium Duck and Grain-Free Duck are two VERY different products!

I challenge Evanger’s to submit samples of the same batch of Grain-Free Duck dog food analyzed by FDA to a third-party lab for testing.

Anyone care to speculate on the outcome?
