This list concerned me since I did not find the food I use (Nature's Logic) on it. I'm also disturbed by the authors of the list (PetSci?) assuming that any food not on their list is doing inhumane lab testing.
I contacted the owner/founder of Nature's Logic about this and received a prompt reply. Since I didn't receive (or ask for) explicit permission to post his reply in a forum, I'll just paraphrase a bit and say that Nature's Logic does not do lab testing of its foods but have had its foods AAFCO tested in feeding trials. Nature's Logic is the only commercial dog food that doesn't use chemically synthesized vitamins and minerals. These synthetic vitamins and minerals do have toxic and lethal dose levels that have been arrived at in lab testing and companies use these results in formulating their products.
Here is a link for vitamin and mineral research from the Nature's Logic web site.
