A federal judge in Illinois has rejected a bid by McDonald's to dismiss a class action lawsuit regarding its popular McRib sandwiches and is allowing the suit to move forward.

The class action lawsuit, which was first filed in December 2025, alleges McDonald's engaged in "false representations, omissions and concealments" when it marketed McRib sandwiches "deliberately crafted to resemble a rack of pork ribs" as "premium" pork rib sandwiches.

The lawsuit alleges the McRib sandwiches don't contain any pork rib meat and are made from lower-grade pork products instead.
