Kirkland Signature, Costco's private label brand, has experienced several significant product recalls since its inception in 1995, primarily due to health and safety concerns. In 2023, frozen organic strawberries were recalled after being linked to a hepatitis A outbreak, impacting consumers across California, Hawaii, Oregon, and Washington, with 10 reported illnesses and 4 hospitalizations. In 2025, nearly 1 million bottles of Kirkland Prosecco were recalled due to safety hazards from spontaneously shattering glass bottles, prompting customers to dispose of the product. The same year, 10,800 units of organic pasture-raised eggs were recalled due to potential salmonella contamination, classified as a severe Class 1 recall by the FDA. Other notable recalls include a 2015 incident involving Kirkland's chicken salad, which was linked to E. coli contamination, and the first major recall in 1998, which involved over 170,000 pounds of frozen ground beef patties due to potential E. coli contamination. These incidents highlight the importance of food safety and the rigorous standards enforced by the FDA.
