The Cholov Stam / akum heter from Rav Moshe Feinstein Z"L not valid anymore?

The USDA, FDA, etc does NOT test for non-cow milk presence, hence the heter is not valid anymore.

This does not affect the fact that the Veterinarian procedures make the cows "TREIF". There is no shishim on the farms.
The USDA doen't either test for other milk.
The fines are minimal.
