They have removed the requirement that these meats be labeled as such. They can still be labeled but Uncle Sam cannot compel the labels to be used.
If the American food producers are smart, they will continue to voluntarily label their products' country of origin and/or production as "AMERICAN."
This could be turned into a great marketing opportunity with the Amercan congressional "lemon" made into "lemonade."
That is what I am hoping...and is what I would do if I were in their position.
Of course, the other shoe that will drop is the new USDA regulations that will provide stiff penalties for producers who do that. Just wait. It will come when some foreign a-hole starts bitching.
