Costco Rotisserie Chicken Lawsuit 2026: The Complete Guide to Both Class Actions

At its January 2026 shareholder meeting, Costco reported that it sold 157.4 million rotisserie chickens worldwide in the past year alone. Tastewise

157 million chickens. At $4.99 each. A price that has not changed since 2009. A product so central to Costco's commercial identity that the company built a $450 million poultry processing complex in Nebraska in 2019 specifically to protect that price point. The Costco rotisserie chicken is not just a food product — it is a commercial institution, a cultural touchstone, and one of the most powerful single-product loss leaders in the history of American retail.

In 2026, that institution is facing scrutiny from two separate class-action lawsuits, both filed this year, that raise questions about what's actually in the chicken and how it's being produced. Tastewise

Two lawsuits. Different allegations. Both in early stages. Both generating significant member concern and significant media coverage.

This guide gives every Costco member the complete, honest, fully sourced picture of both lawsuits — what each alleges, what the current status is, what the evidence shows, what Costco has done in response, and — critically — what none of this definitively means yet, because both cases are in their earliest legal stages with no findings, no settlements, and no established facts beyond the allegations themselves.

At MOJO Sales & Branding, we track every dimension of the Costco ecosystem — including the legal developments that affect member trust in the institution's products.

Lawsuit 1: The "No Preservatives" Labeling Case

Filed: January 22, 2026Plaintiffs: Two Costco shoppers in Southern CaliforniaClaim: False advertising — Costco marketed rotisserie chickens as "preservative-free" when they contain additives that function as preservatives

A class-action lawsuit filed by two Costco shoppers in Southern California claims that the warehouse giant has "systemically cheated customers out of tens – if not hundreds – of millions of dollars" by marketing these rotisserie chickens as preservative-free despite the presence of two additives that function as preservatives. Tastewise

The lawsuit alleges that the "no preservatives" signage on Costco's rotisserie chickens is misleading, as they do contain two preservative-functioning additives: sodium phosphate and carrageenan. Tastewise

What are sodium phosphate and carrageenan?

Sodium phosphate is a food additive approved by the FDA that is used in poultry processing for moisture retention, improved texture, and extended shelf life. It is classified by the FDA as Generally Recognized As Safe (GRAS). Whether it meets the FDA's definition of a "preservative" — which specifically refers to substances used to prevent spoilage — is the central legal question in this case. The FDA's definition of "preservative" is narrower than common usage, and whether sodium phosphate meets that definition as used in this context is a genuinely contested factual and legal question.

Carrageenan is a natural extract from red seaweed used as a thickening and gelling agent in food products. It is also FDA-approved and classified as GRAS. Its classification as a "preservative" is even more contested than sodium phosphate — it is primarily a texture modifier rather than a spoilage preventer.

What did Costco do in response?

In that matter, the company removed in-store signage tied to the claim. Tastewise

Costco's removal of the "no preservatives" in-store signage following the lawsuit's filing is commercially significant — it communicates that Costco's legal team assessed the signage as defensively vulnerable — but it is not a legal admission. Companies routinely remove challenged marketing materials as a risk management measure without conceding the underlying legal claim.

Current status: Early litigation. No settlement. No findings. No claim form. No established facts beyond the allegations.

Lawsuit 2: The Salmonella Contamination Case

Filed: February 12, 2026Plaintiff: Lisa Taylor (proposed class action)Filed by: Animal rights nonprofit-supported legal actionClaim: Costco knowingly sold chickens from a processing plant with chronic, unresolved salmonella contamination

The lawsuit alleges that Costco's Nebraska chicken plant failed USDA salmonella tests 92% of the time since 2019. According to the complaint, the Fremont, Nebraska plant "consistently" fails U.S. Department of Agriculture safety standards, with more than 9.8% of whole chickens and 15.4% of chicken parts testing positive for salmonella contamination. Tastewise

The complaint includes claims that Costco consciously decided to keep its chicken at the $4.99 price point, even if it meant failing to control Salmonella in its chicken supply. Tastewise

Understanding the USDA salmonella testing system

The USDA's salmonella performance standards for poultry plants — the Category 1, 2, and 3 rating system referenced in the lawsuit — measure whether a plant is meeting USDA benchmarks for salmonella prevalence. Category 3, which the lawsuit alleges Costco's Lincoln Premium Poultry plant received in nearly all reporting periods, is the USDA's lowest performance designation — indicating that the plant's salmonella prevalence rate is above the USDA's standards.

Several important contextual points about this testing system that the lawsuit's framing does not always make clear:

First, USDA salmonella performance standards test for the presence of salmonella in raw chicken — which is an ingredient that cooking destroys. The FDA and USDA both consistently communicate that cooking chicken to an internal temperature of 165°F eliminates salmonella contamination. The salmonella in raw chicken that these tests detect is not the same as salmonella in cooked rotisserie chicken — because the cooking process that transforms raw chicken into rotisserie chicken at 165°F internal temperature is specifically designed to eliminate salmonella.

Second, the USDA's Category 3 designation indicates a plant is performing below USDA standards for raw chicken — but it does not indicate that the plant's cooked products are unsafe. The two are related but distinct food safety questions.

Third, the 9.8 percent positive rate for whole chickens and 15.4 percent for chicken parts are rates for raw chicken. These numbers communicate something about the plant's raw product safety practices — they do not directly communicate anything about the safety of the cooked rotisserie chickens that emerge from the same facility after being cooked to 165°F internal temperature.

What happened at the Lincoln Premium Poultry plant?

Costco opened its own $450 million poultry processing complex in Nebraska to keep up with demand and protect that $5 price point. Tastewise

The Lincoln Premium Poultry facility in Fremont, Nebraska — opened in 2019 — is Costco's vertically integrated solution to the rotisserie chicken supply chain challenge. By owning the production facility rather than buying from external suppliers, Costco can maintain the quality specifications and cost structure that make the $4.99 price point sustainable.

The class action, filed by Lisa Taylor, alleges "chronic, uncontrolled and unresolved" salmonella issues at Costco's Lincoln Premium Poultry facility in Nebraska. The lawsuit cites USDA inspection records indicating that the plant has received the worst food safety rating, Category 3, in nearly all reporting periods since 2019, failing monthly salmonella tests from late 2023 through mid-2025. Tastewise

Current legal status:

Costco filed a motion to dismiss the salmonella lawsuit on April 14, 2026. The judge will rule on Costco's motion to dismiss by May 11, 2026. That ruling will determine whether the case proceeds or gets thrown out at this early stage. Tastewise

A motion to dismiss is a standard early-stage legal filing that asks the court to dismiss the case before it advances to discovery or trial — typically on the grounds that the plaintiff's complaint does not state a legally valid claim even if all alleged facts are taken as true. A judge granting a motion to dismiss does not mean the underlying facts were false. A judge denying a motion to dismiss does not mean the allegations have been proven. It means the case may proceed to the next stage of litigation.

No findings, no settlement, no established facts beyond allegations.

What This Means for Members Right Now

The two lawsuits describe two different categories of consumer concern — labeling accuracy and food safety — and they merit different responses from a practical consumer standpoint.

On the labeling case: Whether sodium phosphate and carrageenan meet the legal definition of "preservatives" is a genuinely contested regulatory question that the courts will evaluate.

For members who purchased rotisserie chicken specifically because of "no preservatives" signage and who feel the signage was misleading — the lawsuit is the appropriate legal mechanism for that claim to be evaluated. For members who purchased rotisserie chicken primarily for its value, taste, and convenience — this lawsuit's outcome is unlikely to affect their practical relationship with the product.

On the salmonella case: The distinction between raw chicken salmonella prevalence and cooked rotisserie chicken safety is commercially and practically important. The USDA, FDA, and food safety experts consistently communicate that cooking chicken to 165°F internal temperature eliminates salmonella contamination. Costco's rotisserie chickens are cooked to that temperature as a standard food safety practice. The lawsuit's allegations about the raw chicken plant's performance standards do not directly translate into established risks from eating the cooked product.

That said, the USDA's performance standard system exists for meaningful food safety reasons — plants that consistently score in Category 3 for raw chicken represent a higher-risk processing environment than plants that meet or exceed standards — and the allegations in the lawsuit, if proven in court, would represent a significant institutional food safety failure that merits serious attention.

The responsible consumer guidance: Continue to handle raw chicken from any source with standard food safety practices — keep raw chicken refrigerated, prevent cross-contamination, and cook to 165°F internal temperature. The Costco rotisserie chicken that has already been cooked does not require the same handling precautions as the raw chicken in the plant. Both lawsuits are in their earliest stages and have established no facts — only allegations — about the safety of the cooked product.

The Commercial Context: Why These Lawsuits Strike at Costco's Core

The lawsuits challenge Costco's deeply ingrained brand trust and its "loss leader" strategy, which relies on the popular $4.99 chicken to drive store traffic and membership. While immediate stock impact has been muted, the long-term financial and reputational risks could pressure Costco's premium valuation and membership renewal rates. Tastewise

It is a deliberate loss leader — Costco loses money on every chicken it sells because the price drives millions of customers into its stores, where they spend money on everything else. The chicken is the bait. The membership fees and ancillary purchases are the profit. Tastewise

Understanding the commercial architecture of the rotisserie chicken loss leader is essential context for understanding why two lawsuits targeting this specific product have generated more institutional anxiety than any product liability case of equivalent monetary scale typically would.

The $4.99 rotisserie chicken is not a product that generates direct profit for Costco. It generates something more valuable: institutional trust. Every member who picks up a rotisserie chicken on the way out of the warehouse is experiencing Costco's value proposition in its most tangible, most sensory, most immediate form. The chicken communicates — through its weight, its quality, its price — that Costco is genuinely working on the member's behalf.

Any meaningful erosion of trust in this specific product would affect not just chicken sales but the foundational member trust that generates the 92.1 percent renewal rate that is the most important commercial metric in Costco's business model. The lawsuits are being tracked closely by investors and analysts not because of their individual financial exposure but because of what they represent institutionally.

Together, the two lawsuits put unusual pressure on a product that has long been considered a cornerstone of Costco's brand identity. For a product that built its reputation on consistency and trust, two legal challenges in quick succession mark a notable shift in the conversation. Tastewise

The Bottom Line for Members: What to Do Right Now

If you purchased rotisserie chicken in 2026 and are concerned:

Watch for updates on both lawsuits. The salmonella case's motion to dismiss ruling — expected in mid-2026 — will determine whether the second lawsuit advances. If either case advances to a settlement with a class period that includes your purchases, claim forms and deadlines will be announced through class action notification channels.

For ongoing rotisserie chicken purchases:

The $4.99 rotisserie chicken at Costco remains a fully cooked, ready-to-eat product. Standard food safety handling for prepared chicken applies — keep refrigerated, use within three to four days, reheat to 165°F if reheating. The salmonella lawsuit's allegations about raw chicken at the plant do not change the food safety profile of the cooked product as it exists in the plastic container on the warehouse shelf.

For members who want to follow this story:

Both cases are in their earliest stages. No facts have been established beyond the allegations. No settlements exist. No claim forms are available. The appropriate posture for members concerned about either case is informed attention — following the legal developments as they unfold — rather than either immediate legal action (which is not yet available) or complete dismissal of the allegations (which would be premature given the USDA data cited in the salmonella complaint).
