Costco Sued Over ‘No Preservatives’ Claim as Food Labeling Lawsuits Gain Attention

Costco is facing a proposed class-action lawsuit alleging that one of its pasta products falsely advertised a “no preservatives” claim despite containing manufactured citric acid, according to legal filings cited in published reports.

The lawsuit argues that shoppers may have been misled by packaging that promoted the product as preservative-free. The allegations have not been proven in court.

The case is drawing attention because ingredient-label disputes involving terms like “natural,” “healthy,” and “no preservatives” often generate strong consumer reaction online, especially when major grocery retailers are involved. Shoppers increasingly scrutinize ingredient lists and marketing claims as food prices remain elevated and consumers pay closer attention to product quality.
