Got milk? Maybe not.

Federal regulators signaled this week they intend to crack down on non-dairy products billing themselves as “milk” — reversing a trend that allowed soy and almond drinks to proliferate on supermarket shelves.

Federal rules, which have largely gone unenforced, define the mom-pleasing, bone-building milk as coming from the “milking of one or more healthy cows.”

Word of the change came from the Food and Drug Administration’s top boss, Commissioner Scott Gottlieb, at an event in Washington D.C.

“The question becomes, ‘have we been enforcing our own standard of identity?’” Gottlieb said at the Politico event Tuesday. “The answer is probably not.”

It’s one of hundreds of standards maintained by the federal government spelling out how foods with various names need to be manufactured and identified.

The change would likely spoil the branding strategy employed by makers of soy and almond drinks.

But the change wouldn’t come immediately. Federal regulations require the FDA first issue guidance notifying companies of the change and ask for public comment. That guidance will probably be issued in a year, Gottlieb said.

This is just the latest in a series of agriculture industry spats over what alternative food products can be labeled as American diets evolve. Recent fights include battles over the definitions of mayonnaise and yogurt — and futuristic science that could allow meat to be grown by culturing cells.

The National Milk Producers Federation, which has been pushing for such a crackdown, said it welcomed Gottlieb’s statement.

The Good Food Institute, which advocates for plant-based alternatives, says the term “milk” should be permitted with modifiers for nondairy drinks.

“For the same reason that you can have gluten-free bread and rice noodles, almond milk and soy milk are the most clear and best terms for describing those products,” said Bruce Friedrich, the group’s co-founder.
