Recently, a food safety warning concerning Costco has attracted considerable attention when a widely loved bakery snack was voluntarily recalled from sale in several American states and territories.
The problem relates to Traditional Madeleines, a dessert that is known to be available in the form of plastic shells at bakery counters in the warehouses. As reported by the company, the snack was recalled due to a labelling mistake resulting in the presence of undeclared allergens. According to the official notice released by Costco, in particular, the warning impacts the customers who bought the product within a short period at the end of March and the beginning of April 2026.
Although the snack may appear to be safe at first glance, the actual problem lies in the ingredients that are not included in the label.
Traditional Madeleines recall at Costco sparks allergy warning over undeclared hazelnuts and soy
The recalled item is the “Traditional Madeleines” bakery pack. These are soft sponge-like cakes usually sold in clear plastic trays.The problem started when some packs were mistakenly filled with a different version of the product. Instead of the standard madeleines, certain containers included madeleines containing chocolate hazelnut spread.
Hazelnuts were not declared on the label. Soy was also present in the product without proper mention. Both ingredients can trigger allergic reactions in sensitive individuals.The recall covers items sold between March 30 and April 6, 2026.

Food allergies and allergen risks in Costco madeleines recall
Sometimes food allergies can be quite hard to predict. In fact, even small traces of the substance can cause the person to experience a reaction. Hazelnut is part of tree nuts, which are one of the most frequent triggers of severe allergic reactions. Some of the symptoms associated with it may be skin irritation, swelling, difficulty breathing, and even anaphylaxis.
The second substance, soy, is another widely used allergen.However, the problem does not consist in the fact that the substances used are somehow exotic, but rather in their non-disclosure.
What shoppers should do now
Consumers of Traditional Madeleines at the affected stores within the period mentioned above have been requested not to eat the product.Consumers should instead take the product back to the nearest Costco store, where they will get a full refund for the product. In most cases, receipts for recalled goods are not usually necessary since the stores can track the transaction using membership information. In case one has consumed the product and is feeling ill, they should see a doctor immediately. In severe cases, allergic reactions develop very fast.Through an announcement made to all members, consumers with hazelnut and soy allergies were warned not to eat the product at all.
