The US Food and Drug Administration seems to have soured on nondairy milk-alternative products that use the term “milk” in their marketing and labeling—like popular soy and almond milk products.

In a talk hosted by Politico, FDA Commissioner Scott Gottlieb announced Tuesday that the FDA will soon issue a new guidance on the use of the term. But he added that products aren’t abiding by FDA policies as they stand now. He referenced a so-called “standard of identity” policy that regulates how milk is defined and should be identified.

“If you look at our standard of identity—there is a reference somewhere in the standard of identity to a lactating animal,” he said. “And, you know, an almond doesn’t lactate, I will confess.”
