Ah - may have found some more clarification:
There are a huge variety of quality with ‘meals’ in pet food. Some dog food and cat food ‘meal’ ingredients are provided by the Rendering Industry; known as the ‘Original Recyclers’. The Rendering Industry collects items that otherwise would have to be disposed of, and cooks (renders) them into sellable products to various other industries such as the pet food industry. ‘Items that otherwise would have to be disposed of’ include (but is not limited to) livestock animals rejected for use in human food because of disease, euthanized animals (ANY euthanized animal), road kill, used restaurant grease, and expired grocery store meat. Common pet food ingredients produced by the Rendering Industry are ‘Animal Fat’, ‘Meat and Bone Meal’, ‘Meat Meal’, and ‘Animal Digest’.
‘Meat and Bone Meal’ and ‘Meat Meal’ are NOT the highest quality pet food ingredient. There is a tremendous possibility that either of these ‘meal’ ingredients contain the cooked remains of a diseased animal and a tremendous possibility that either of these ingredients contain a lethal drug (pentobarbital) used to euthanize the diseased animal. Thus…these ‘meal’ ingredients easily could be considered ‘bad’ (risk) pet food ingredients.
On the other hand however, there is the common dog food or cat food ‘meal’ ingredient ‘chicken meal’ (or similar specific meat meal ingredient such as ‘turkey meal’). Chicken meal is as well a ‘rendered’ ingredient; however it from a completely different processing facility as those that provide ‘meat and bone meal’ and ‘meat meal’ ingredients. In most cases, facilities that produce chicken meal (or similar meat specific meals) ingredients are attached to human meat processing plants (versus independent meat rendering facilities that produce meat and bone meal and meat meal ingredients). Chicken meal, is generally perceived to be a higher quality pet food ingredient. However, just like all meal ingredients, chicken meal can vary in quality too.
Chicken meal (or similar specific meat meal ingredients) can be made from muscle meat only, or it can contain bone and or internal organs.............Thus, pet food meal ingredients that contain bone could be considered a risky ingredient and of lesser quality. Some pet food manufacturers use a muscle meat only chicken meal, while others use muscle meat and bone.
