In September the FDA decided its relaxed enforcement measures had been so successful in keeping inventories stocked that it extended them through 2025. However, following a pressure campaign from the U.S. dairy industry, Congress’s temporary tariff suspension is set to expire at the end of this year.

They have a funny way of showing it.
