Diamond foods has announced a recall of their Premium Edge cat foods. Several cases were posted in the past 1-2 weeks on our veterinary computer network, and thanks to some astute detective work and a little bit of luck, a rash of cats with severe neurologic symptoms was tracked down to food that was deficient in thiamin, most likely due to poor quality control during processing.
My personal opinion in this case...Diamond is involved WAY too often in recalls with fairly serious implications. This is something I worry about with many of the specialty "boutique" type foods, typically sold only through pet stores, generally at the high end of the price range, but often from smaller companies who just don't have the resources to maintain the safety and quality control of some of the larger companies. Often they are rated quite high on lists produced by companies such as the Whole Dog Journal; but their ratings seem to be based only on label comparisons which tell only a small part of the story. As a matter of fact, WDJ's top rated food was involved in a huge recall several years ago in which a number of dogs died; the actual source of the problem was never identified to my knowledge but a number of problems and deficiencies with the diet were identified in trying to track down the source of the problem.
I think also you have to be aware of and differentiate between industry wide issues, such as the big melamine problem a couple of years ago; recalls for minor issues to be on the safe side, and recalls in which serious illness or death occurred due to quality control and processing issues. The latter issue is one that I look at when evaluating food quality. Buyer beware!
