Alltech, a grassland product manufacturer that sells dairy products for foodservice companies, has been accused of using an outdated and misleading name for a product made from genetically modified crops.

Alltech, based in Illinois, uses the terms “all dairy,” “dairy product,” and “all” instead of the more familiar “ditch cow.”

It’s not the first time Alltech has been the target of controversy.

In 2011, the company was sued by the Center for Food Safety and Consumers Union for using the word “cow” when describing its products.

The Center for Consumer Freedom filed a complaint with the Food and Drug Administration (FDA) alleging that Alltech used the term “cow,” which was deemed to be an outdated term.

The agency did not act on the complaint, but in December 2016, the agency published an opinion by the Office of Management and Budget (OMB), which said the FDA had not identified any “material inconsistency” between the Alltech name and the USDA definition of a “cow.”
