Passing AAFCO trials simply means it is tested to be a nutritionally complete food, not a premium food. It means that it is not nutrient deficient, and that is very important from a food safety standpoint.Originally Posted by SweetPea24
Just because a food meets AAFCO guidelines does not make it a great food. Beneful probably meets AAFCO guidelines for dog food but it's a terrible food.
The commercial raw foods presented to the AVMA were said to be nutrient deficient for example, and we have demonstrated that cats have in fact died from lacking macro or micro nutrients. If you recall somewhat recently on the forum the post about Wellness cat food that was quickly recalled due to suspected vitamin B1 deficiency in the food that did not meet AAFCO minimums. A regular Joe or Jane may not realize when the diet they have created is lacking in vitamin B1, as they have no means of testing this, no others to provide advanced warning of concerns, or random lot inspections, so the first sign is when the cat starts showing symptoms. In the case of some deficiencies, the first outwardly visible symptom can be blindness or heart failure.
Of course that does not mean that Friskies is an excellent protein source fantastic food because it meets AAFCO nutrient minimums, but it absolutely means that unregulated home-fed raw diets or pet food that is not verifiably listed as nutritionally complete represent a potential risk for deficiencies.
