Walmart (wmt) is getting sued for a surprising reason, especially for cheese-lovers.
The retailer has reportedly received a lawsuit for selling Parmesan cheese with wood filler, Bloomberg reported. The cheese sold in stores had been labeled pure and 100% Parmesan, but the Walmart Great Value band was ultimately found to contain other ingredients.
In fact, there was reportedly as much as 10% cellulose, which is a wood-based agent for anti-clumping, found in the product, according to the complaint, which was filed in a Manhattan federal court. A customer Marc Moschetta filed the lawsuit, saying, “the 100% representation was false and mis-characterized the amount and percentage of Parmesan cheese in the container.”
Moschetta wants a class action lawsuit in order to press Walmart on the matter, Bloomberg reported. The move comes after an earlier investigation by the publication as well as another investigation by the Food and Drug Administration, as Fortune wrote earlier this month.
“We know earning customer trust starts with high standards for the products we carry. We take this matter seriously,” Randy Hargrove, a spokesperson for the retailer, said in a statement to Fortune. “We will review the allegations once we have received the complaint and will respond appropriately with the court.”
