Costco Rotisserie Chicken Lawsuit 2026: Claims, Response & Full Update
Costco’s famous $5 rotisserie chicken is once again in the spotlight after a legal dispute over its ingredients and marketing claims. The company is facing a proposed class-action lawsuit alleging that its Kirkland Signature rotisserie chicken contains ingredients that customers believe were misrepresented as “no preservatives.”
However, Costco strongly rejects these claims and has asked the court to dismiss the case, calling the lawsuit “fatally flawed.”
What Is the Costco Rotisserie Chicken Lawsuit?
The Costco rotisserie chicken lawsuit was filed by two California customers who claim the product contains additives such as carrageenan and sodium phosphate, while being advertised as free from preservatives.
The lawsuit argues that:
- Costco misled consumers with “no preservatives” claims
- Customers paid a premium based on this advertising
- The product violates consumer protection laws in California and Washington
The plaintiffs are seeking:
- A halt to the “preservative-free” marketing claims
- Financial damages for customers
- Class-action status for U.S. buyers
Costco’s Response to the Allegations
Costco, headquartered in Issaquah, Washington, strongly denies wrongdoing.
According to its legal filing:
- The company states the lawsuit is “fatally flawed”
- Carrageenan and sodium phosphate are not classified as preservatives under U.S. Food and Drug Administration rules
- These ingredients are used as seasoning and stabilizing agents, not preservatives
Costco’s attorney also argued that the complaint fails to show any clear financial harm to customers.
The company further stated that the plaintiffs do not identify any competitor selling a rotisserie chicken at a lower price than $4.99.
What Are Carrageenan and Sodium Phosphate?
The lawsuit centers around two common food additives:
- Carrageenan: A seaweed-derived ingredient used to thicken and stabilize processed foods
- Sodium phosphate: Used for moisture retention, emulsification, and texture improvement
Both are widely used in packaged and prepared foods in the U.S. food industry.
Why Costco’s $5 Rotisserie Chicken Matters
The Costco rotisserie chicken is one of the retailer’s most iconic loss-leader products, priced at $4.99 in the U.S. for years despite inflation pressures.
It is known for:
- High sales volume in Costco warehouses
- Consistent pricing strategy
- Strong customer demand and brand loyalty
Because of its popularity, any legal challenge around its ingredients attracts significant consumer attention.
Key Legal Argument from Both Sides
Plaintiffs’ Argument
- Product labeling is misleading
- Consumers believed they were buying a preservative-free chicken
- Costco gained unfair advantage through advertising claims
Costco’s Defense
- Ingredients are not preservatives under FDA definitions
- No measurable consumer harm is proven
- Pricing allegations are unsupported
Possible Outcome of the Case
At this stage, the court has not made a ruling. Costco is currently asking for dismissal of the case in U.S. District Court for the Southern District of California.
If the case continues, it may:
- Move toward class-action certification
- Require deeper ingredient and labeling review
- Set precedent for “preservative-free” food labeling claims
