The website Pet Food Recall Facts is putting out a call for unopened canned/pouches of old pet food for testing:
If any pet owners have unopened samples of pet food manufactured prior to the end of December 2006, and would be willing to make them available for testing, please contact me. The samples I’m interested in would be store brands with expiration dates of “09” for canned food and “08” for pouches. I’m interested in the “loaf” style of pet food that does not list gluten as an ingredient. If anyone has such samples available for testing, I would most sincerely appreciate your making them available. Personal information of those making samples available will be held in the strictest confidence.
