The Trump administration is taking aim at “Big Egg,” alleging that some of the nation’s largest egg producers illegally conspired to drive up consumer prices.

The lawsuit, filed by the Justice Department’s Antitrust Division on Tuesday alongside attorneys general from 17 states, names Cal-Maine Foods, Hickman’s Egg Ranch, and Versova Holdings and affiliated companies. Prosecutors allege the companies conspired for years to manipulate industry price benchmarks that influence wholesale egg prices nationwide.
