Costco Lawsuit Tests Member Trust And Kirkland Labeling Commitments

A class-action lawsuit has been filed against Costco, alleging misleading “No Preservatives” labeling on its Kirkland Signature Rotisserie Chicken. This case challenges Costco’s brand promise of quality and labeling accuracy, particularly for its key Kirkland private label, which is central to its value proposition and member trust. The outcome could impact Costco’s marketing, formulation costs, and how it communicates with members regarding its private label products, while investors will watch for potential legal exposure and brand reputation effects.
