A labeling mix-up at Costco Wholesale has triggered a product recall affecting shoppers at select store locations across the country, raising serious concerns for customers with tree nut allergies who may have unknowingly taken home a product that could put their health at risk.
The recall centers on packages sold as Traditional Madeleines that actually contain a different product entirely — chocolate hazelnut-filled madeleines. Because the label never disclosed the presence of hazelnuts, the packaging fails to meet the allergen disclosure requirements set by the U.S. Food and Drug Administration, which mandates that tree nuts be clearly identified on food labels.
What's Actually Inside the Package
The product at the center of the recall is listed under item number 2000012, labeled as Traditional Madeleines. What customers actually received, however, was item number 2011285 — a mixed assortment of heart-shaped cookies, some filled with raspberry and others filled with chocolate hazelnut. For most shoppers, that might seem like a pleasant surprise. For anyone living with a tree nut allergy, it's a potentially dangerous one.
Hazelnuts are classified as a tree nut, a category of allergens known to trigger reactions that range from mild discomfort to anaphylaxis — a severe, life-threatening response that can require emergency medical treatment. The problem here isn't the ingredient itself but the fact that consumers had no way of knowing it was present. The label said one thing, and the product delivered something else entirely.
Where and When the Cookies Were Sold
According to Costco, the affected packages were sold at select warehouse locations between March 30 and April 6, 2026. The recall touches stores spread across a wide geographic range, hitting communities in Montana, Washington, Illinois, Wisconsin, California, Colorado, Florida, Virginia, and Puerto Rico.
The specific locations include stores in Missoula, Mont.; Burlington, Wash.; East Peoria, Ill.; Bellevue, Wis.; Pleasant Prairie, Wis.; Chico, Calif.; Thornton, Colo.; Gilroy, Calif.; Bayamon, Puerto Rico; Pembroke Pines, Fla.; and Fairfax, Va.
Anyone who purchased Traditional Madeleines at one of these locations during that window should check the item number on the packaging before consuming the product or serving it to others.
Why This Kind of Mistake Matters
Labeling errors of this type aren't just bureaucratic slip-ups — they carry real-world consequences. Tree nut allergies are among the most common and most serious food allergies in the United States. Unlike some sensitivities that cause discomfort, tree nut reactions can escalate quickly and without much warning. For a household where someone manages a known allergy, the assumption that a product is safe based on its label is not paranoia — it's the entire system working as intended.
That system broke down here. A shopper with a tree nut allergy who picked up a bag of what appeared to be plain Traditional Madeleines had every reason to believe the product was safe. There was nothing on the label to suggest otherwise.
The FDA requires major food allergens — including tree nuts like hazelnuts, almonds, cashews, and walnuts — to be clearly disclosed on packaging. When that requirement isn't met, whether by accident or oversight, the consequences can fall on the people least equipped to absorb them.
What Shoppers Should Do
Customers who purchased the product during the affected dates at any of the listed store locations are encouraged to stop consuming the cookies immediately and to check whether the item number on the package matches the recalled product. Costco has issued a news release addressing the recall, and the company has been proactive in notifying shoppers through its standard recall channels.
For those with tree nut allergies in their household, this is also a useful reminder to double-check even familiar or trusted products, particularly when buying in bulk. Warehouse retail is built on volume, and packaging errors — while rare — are not unheard of. The scale at which stores like Costco operate means that even a short sales window of one week across eleven locations can put a significant number of packages into consumers' hands.
The USDA Food Safety and Inspection Service maintains ongoing resources for consumers looking to understand more about unreported allergens and how food labeling laws are designed to protect public health.
