This is a post from another board that I am on- FYI on Canidae
A friend bugged me until I sent samples of the dog foods I feed (Canidae & California Natural) to be tested. The lab called with preliminary results on Friday, and said not to feed either food, until they ran separate tests on the CA Natural (lamb & rice puppy & adult), and Canidae (Original and Lamb/Rice). They had mistakenly combined my two separate samples, and ran one test, instead of two. Got the final results yesterday. The Canidae is contaminated with acetaminophen, the main ingredient in Tylenol. Acetaminophen is immediately fatal in cats, and if fed to dogs over a period of time will cause terminal liver & kidney damage. I'm still in shock.
If you know anyone who feeds Canidae, have them look closely at the dates stamped on the bottom of the sack. It's hard to find. Here's what's stamped on the sacks I had tested: Canidae Original RM 7/7/07, use by 7/7/08; Canidae Lamb & Rice L&R RM 7/6/07, use by 7/6/08.
Perhaps someone else will pay the big price ($250/test) to test the original and lamb/rice separately to see if either or both are contaminated. I called my dealer yesterday and she's going to call the company. This is scary--that the problems also exist with top brands of dog food.
