Costco Sued for Selling Protein Powder ‘Tainted’ with Heavy Metals
Costco Wholesale Corp. is facing a proposed class-action lawsuit accusing the retailer of selling Orgain Organic Protein Powder that allegedly contains toxic heavy metals while marketing the product as “high quality, clean, and nutritious” without warning consumers about the potential contamination. The lawsuit, filed in the U.S. District Court for the Western District of Washington, claims Costco violated consumer protection and false advertising laws by failing to disclose the presence or risk of lead, cadmium, and arsenic in the product.
The lawsuit was brought by seven consumers who allege they purchased the protein powder believing it was a safe, healthy nutritional supplement. According to the complaint, Costco’s marketing emphasized quality ingredients and clean nutrition, leading customers to reasonably expect the product to be free of harmful contaminants. The plaintiffs argue that they would not have purchased the product—or would have paid less for it—had they known about the alleged heavy metal content.
The complaint relies on findings from independent testing, including reports by the Clean Label Project and Consumer Reports, which detected measurable levels of heavy metals in several protein powders, including Orgain products. Consumer Reports previously found that Orgain’s Vanilla Bean protein powder exceeded its recommended “level of concern” for lead, while the plaintiffs also commissioned laboratory testing that allegedly confirmed the presence of lead, cadmium, and arsenic in the products sold by Costco.
According to the lawsuit, exposure to heavy metals may pose significant health risks because these substances can accumulate in the body over time. The complaint alleges that Costco either knew or should have known about the contamination through its quality control and supply-chain oversight but continued selling the products without warning consumers. The plaintiffs contend that ordinary shoppers have no practical way to detect heavy metals without specialized laboratory testing and therefore relied on Costco’s representations about the product’s safety and quality.
The lawsuit includes claims for deceptive business practices, fraudulent concealment, false advertising, and violations of multiple state consumer protection laws. It seeks class-action status on behalf of consumers who purchased the affected Orgain protein powder from Costco stores or through Costco’s website. The plaintiffs are requesting monetary damages, restitution, and a court order requiring Costco to disclose heavy metal levels in the products it sells and to stop marketing allegedly contaminated products without adequate warnings.
Neither Costco nor Orgain immediately responded to The Guardian’s request for comment. However, Orgain previously told the Seattle Times that while trace amounts of naturally occurring substances may be present in plant-based ingredients, its products comply with applicable food safety standards and guidance. The company said it stands behind the safety and quality of its protein powders.
The case also highlights broader concerns about the regulation of dietary supplements and protein powders in the United States. Unlike many prescription medications, protein supplements are not subject to pre-market approval by the U.S. Food and Drug Administration, meaning consumers often rely on manufacturers’ marketing claims regarding product purity and safety. The plaintiffs argue that this makes accurate product labeling especially important for health-conscious consumers.
The lawsuit does not allege that Costco manufactured the protein powder. Instead, it focuses on the retailer’s alleged responsibility for selling and promoting the product while failing to disclose information about potential contaminants. As the litigation proceeds, the court will determine whether the plaintiffs can establish that Costco engaged in deceptive marketing practices and whether consumers are entitled to damages or injunctive relief.
