Costco Canada Recalls Dubai Style Chocolate Mousse Over Life-Threatening Allergy Risk

Costco Canada has issued a recall notice for a dessert product sold in warehouses nationwide, warning that undeclared nut ingredients may trigger severe allergic reactions in sensitive individuals. The item involved is a Dubai-style chocolate mousse sold under the Delici brand, and the recall centers on specific best-before dates tied to certain lot codes. If you purchased the product in recent weeks, Costco says you can return it to a warehouse in Canada for a full refund.

The concern is especially urgent for anyone with allergies or sensitivities to cashew nuts or macadamia nuts. Even small traces of these allergens can cause rapid-onset reactions for some people, and recalls like this are typically issued when a label may not reflect the product’s full allergen profile.

What Costco Canada is recalling

The recall involves Delici Dubai Style Chocolate Mousse, a dessert sold through Costco warehouses in Canada. The notice says the product is being voluntarily recalled due to the possible presence of cashew nuts and macadamia nuts that are not declared on the label. For shoppers who rely on allergen statements to make safe choices, missing declarations can turn an everyday dessert into a serious health risk.

How to identify the recalled chocolate mousse

Costco’s recall notice specifies the exact product details to help members confirm whether what they bought is part of the affected lots. Check your packaging for the following identifiers:

• Product: Delici Dubai Style Chocolate Mousse
• Costco Item number: 1990644
• Package size: 6 × 76 g
• UPC: 812190020825
• Sold in Canada: Costco warehouses (purchase window noted as January to February 2026)

Costco advises identifying affected items by best-before dates printed on the packaging. If your pack matches any of the dates below, treat it as part of the recall and follow the return instructions.

Why undeclared nuts are treated as a high-risk recall

Food recall notices often use careful language, but allergen recalls are among the most serious because reactions can escalate quickly. For some people, exposure to undeclared nuts can cause symptoms that range from hives and swelling to breathing difficulties and anaphylaxis. That’s why the recall warning frames the risk as potentially life-threatening for sensitive individuals.

Even if you’ve eaten the dessert before without issues, the recall applies to specific production lots. Ingredient cross-contact, supply changes, or labeling mismatches can affect certain batches, which is why matching the best-before dates is so important.

What to do if you bought the recalled dessert

If you have the Delici Dubai Style Chocolate Mousse with an affected best-before date, the safest move is to stop consuming it immediately. Costco says customers can return the product to a Costco warehouse in Canada for a full refund. Keeping the packaging can help staff verify the item and date codes quickly, but Costco warehouses typically have processes to handle returns even if the packaging is incomplete.

If you think someone may have had an allergic reaction after eating the product, seek medical attention right away. Allergic symptoms can worsen quickly, and healthcare professionals can assess severity and provide appropriate treatment.
