Can meat grown in a lab still be called meat? Can milk that comes from nuts rather than cows bear the name milk? And can mayonnaise made without eggs still be called mayo?
From oat milk to grain-based burger patties to mayo made from yellow peas and canola oil, alternative products now populate nearly every aisle of the grocery. Makers of alternative foods, usually from plants, use the terms to signal how their products can be used.
But farmers see the new foods as a threat and want the federal government to restrict words like milk, cheese and meat to products that come from animals.
The FDA appears poised to reconsider terms. "It's important that we take a fresh look at existing standards of identity in light of marketing trends and the latest nutritional science," FDA Commissioner Scott Gottlieb said in March.
Some see a risk of confusing consumers, who may think the new products have the same origin as the ones they've long known. Chocolate-flavored dairy milk is called chocolate milk, for instance, but cashew milk is strained from a mixture of ground cashew paste and water.
Another part of the confusion is tied to the origin of the new products. In meats, the new alternatives that are coming out of labs still use animal cells.
The debate intensified recently when Cargill, Tyson and billionaires Bill Gates and Richard Branson invested in Memphis Meats, a Berkeley, Calif.-based company that takes animal cells and cultivates them into meat. It produced a meatball in 2016 and its first poultry product last year.
Minnetonka-based Cargill is one of the world's largest processors of beef, so cattle ranchers took its involvement as a serious omen: It's not a matter of if, but how soon, lab-raised meat becomes a player in the market.
