Honestly, I don't know how much more clear it can get. While the USDA and FDA do not directly regulate some things that the FTC handles, the FCT will look at USDA/FDA pronouncements and regulations to make judgments about the things that they do handle.
We're not trying to say they don't act together.
We're trying to say that 3body is misapplying a specific regulation from one of those agencies/departments/bureaus. The regulations for what raw ground beef can contain pertain only to those who are making the raw ground beef.
Let us assume the raw ground beef has been made in accordance with those regulations. It is 100% USDA raw ground beef.
Let's further assume that Taco Bell contracts with Tyson Foods to purchase 100 pounds of "taco meat filling," which Tyson Foods will prepare, package, and label according to both the federal regulations which apply, and the conditions Taco Bell requires. Federal laws and regulations will always take precedence over Taco Bell's conditions, where applicable.
Tyson Foods then acquires however many pounds of 100% USDA raw ground beef and however many pounds of Taco Bell's seasoning mix the recipe requires. (I say this because when cooked, ground beef undergoes some shrinkage through the loss of fats and water. If you cook 100 lbs of ground beef, it will weigh something less than 100 pounds after cooking and draining. So I don't know how much you would purchase raw to equal 100 lbs cooked weight, plus the weight of the added seasonings and water. Let's assume the numbers are known to someone.

)
The raw ground beef is then prepared (steamed, boiled, fried, whatever method), and the excess liquids (assuming fats and water) are drained off.
The
raw ground beef product is now a cooked ground beef product, and the regulations for what it may contain as raw ground beef no longer apply, because it has already been processed, packaged, sold, and cooked, and now is no longer raw. It contained no fillers or extenders or added water when it was processed and when it was sold. This is the point I and others are trying to make. The regulations are going to be different for those two different products.
Now the regulations for whatever product it is to be made into come into effect. It is to be made into "taco meat filling," and this product
can contain fillers and extenders, because it only has to be 40% fresh beef.
This cooked ground beef is to be combined with Taco Bell's seasoning mix, and water (and to the best of my knowledge, pending the trial), nothing else. That's what the trial is supposed to be determining, at least in part. Does Taco Bell's "taco meat filling" meet the minimum requirement of 40% beef, or is it only 36% as claimed?
A product labeled "taco meat filling" must contain at least 40% ground beef (or beef, or meat) to bear that label. This product does bear that label, and Taco Bell avows the content is more than double what is required. Their taco meat filling is 88% cooked ground beef, and 12% seasoning mix and water. The trial is to determine if that is accurate by determining what actually is in the taco meat filling,among other concerns.
So:
Is the raw ground beef used to make this product in accordance with the USDA regulations regarding raw ground beef?
Does the finished product, "taco meat filling," meet or exceed the requirements for that product?
Can Taco Bell market this taco meat filling as "seasoned ground beef?"
If it contains exactly that--ground beef and seasoning--is that a legitimate, reasonable, legal, appropriate marketing description for that product?
Is the public being misled in any step of this process?
