Costco Chicken Lawsuit: "No Preservatives" Claim Challenged
29 Jan
Summary
- Lawsuit alleges Costco falsely advertised rotisserie chicken as having no preservatives.
- Added preservatives sodium phosphate and carrageenan are cited in the legal filing.
- Costco removed signage related to preservatives following the lawsuit.

A class action lawsuit has been filed against Costco by two California women who allege the retailer misled consumers about its Kirkland Signature Seasoned Rotisserie Chicken. The plaintiffs, Bianca Johnston and Anastasia Chernov, claim the chicken is advertised as containing "no preservatives" but is actually made with sodium phosphate and carrageenan.
These ingredients, the lawsuit asserts, perform preservative functions by enhancing shelf stability, texture, and moisture retention. The plaintiffs contend that Costco's advertising violated consumer protection laws in California and Washington, leading to alleged unfair business practices and consumers paying a premium for a product not as described.
