Costco is asking a court to dismiss a proposed class-action lawsuit that challenges how its Kirkland Signature Seasoned Rotisserie Chicken is labeled. The complaint alleges the product includes two added preservatives, but that the ingredients are not labeled as preservatives as required by U.S. Food and Drug Administration (FDA) rules. According to the reporting, the retailer argues that the ingredients are properly handled under applicable regulations and disputes the basis of the claims. The lawsuit is framed as a consumer case, with plaintiffs seeking to represent other purchasers who bought the rotisserie chickens. One outlet reports that Costco’s position includes that the relevant ingredients are not required to be listed as “preservatives” in the manner asserted by the plaintiffs, referencing FDA labeling requirements. Another outlet describes Costco’s response to the core allegation that the chickens are mischaracterized through labeling. The dispute centers on whether the product’s ingredient disclosures satisfy FDA labeling standards for added preservatives, not on the product’s safety or flavor.
