Costco recalls popular product in 2 states over potential ingredient mix-up

The U.S. Department of Agriculture (USDA) has issued a warning for Costco shoppers in the Northeast.

A major mislabeling error has turned a standard beef dinner into a potential medical emergency for those with shellfish allergies. Giovanni Rana ravioli — specifically the "Rustic Beef Sauce & Creamy Burrata Cheese" variety — may actually contain shrimp and lobster sauce.

"The shrimp and lobster, known allergens (shellfish), are not declared on the product label," the USDA’s press release reads.
