Costco Madeleine Recall: Tree Nut Allergy Risk Alert

If you recently picked up a box of Traditional Madeleines from Costco, stop before you open the package. Costco has issued an urgent recall affecting customers who purchased the product between March 30 and April 6, 2026 — and if you or anyone in your household has a tree nut allergy, the risk could be life-threatening. This recall is active right now, and here's everything you need to know.

What Is the Costco Madeleine Recall?

On April 7, 2026, Costco issued a voluntary recall for its Traditional Madeleines (item #2000012) after discovering a serious mislabeling error. According to USA Today, packages labeled as Traditional Madeleines were actually found to contain Chocolate Hazelnut-filled Madeleines — a completely different product with a very different ingredient profile.

The core danger here is undeclared allergens. The Chocolate Hazelnut-filled variety contains Tree Nuts (Hazelnut/Filbert), which are not listed anywhere on the Traditional Madeleine packaging. For the vast majority of shoppers, this is an unpleasant surprise. For the estimated 1–2% of the population with tree nut allergies — many of them children — it could trigger a severe or even fatal allergic reaction.

Costco acted swiftly, sending recall notices directly to affected members who purchased the product at select warehouse locations during the affected sales window of March 30 through April 6, 2026.

Who Is at Risk and Why Tree Nut Allergies Are Serious

Tree nut allergies are among the most common and dangerous food allergies in both children and adults. Unlike some childhood allergies that can be outgrown, tree nut allergies are frequently lifelong. Hazelnuts — one of the undeclared allergens in this recalled product — are a well-documented trigger for immune responses that range from mild itching and hives to full-blown anaphylaxis.

Anaphylaxis is a rapid, systemic allergic reaction that can cause:

• Swelling of the throat and airway
• Severe drop in blood pressure
• Loss of consciousness
• Death if not treated immediately with epinephrine (such as an EpiPen epinephrine auto-injector)

The especially alarming aspect of this particular recall is that customers purchasing Traditional Madeleines had no reason to suspect the product contained any nuts. Those who carefully read labels and avoid hazelnut-containing products could unknowingly consume one of these mislabeled packages. Undeclared allergens are among the leading causes of food recall-related hospitalizations in the United States.

If you or a family member consumed any of the recalled product and experienced symptoms such as tingling in the mouth, hives, stomach cramps, or difficulty breathing, seek emergency medical attention immediately.

How to Check If You Have the Recalled Product

Here's how to determine whether you're holding a recalled item:

• Item Number: Look for item #2000012 on the packaging or your receipt
• Purchase Window: The affected products were sold between March 30 and April 6, 2026
• Location: Select Costco warehouse locations — Costco has already notified affected members directly via email or account alerts
• Product Name on Label: The outer packaging reads "Traditional Madeleines" but the contents are Chocolate Hazelnut-filled Madeleines

If your box matches any of the above, do not consume the product. Place it in a sealed bag and return it to your nearest Costco warehouse for a full refund — no receipt required. Costco's member-based system makes it straightforward to process returns for recalled items.

A Pattern of Recent Recalls at Costco

While this madeleine recall is the most urgent food safety alert at the moment, it is worth noting that Costco has faced several recalls in quick succession in early 2026. This doesn't necessarily reflect systemic failures at Costco — large retailers with high sales volumes are statistically more likely to be touched by supplier-level recalls — but it does underscore the importance of paying attention to recall notices.

In March 2026, Costco recalled a premade meatloaf meal kit sold in nearly 30 states due to possible Salmonella contamination — a bacterial pathogen capable of causing serious gastrointestinal illness, particularly dangerous in children, the elderly, and immunocompromised individuals.

Around the same time, MassLive reported that the U.S. Consumer Product Safety Commission recalled over 740,000 sauté pans sold at Costco, Walmart, and Amazon due to burn hazards. According to MSN, the handles on these sauté pans were prone to detaching during use, posing a risk of serious burns from hot oil or food.

These incidents come amid a broader wave of consumer product safety alerts. MSN also reported that Walmart issued recalls on thousands of products with the warning to "stop using immediately," and a nationwide recall was issued for 6,200 bottles of a popular hair product. Shoppers in 2026 are well-advised to keep a close eye on their inboxes and the USDA and FDA recall databases.

What You Should Do Right Now

Whether or not you have a known allergy in your household, here are the recommended immediate steps:

1. Check your pantry for Costco Traditional Madeleines (item #2000012) purchased between March 30–April 6, 2026
2. Do not eat the product — not even a small amount to "test" it
3. Return the product to Costco for a full refund — you do not need your receipt
4. Check your Costco account or email — affected members were directly notified by Costco
5. If symptoms occurred after consumption, seek medical attention immediately and note the product details for your doctor
6. Consider keeping an epinephrine auto-injector on hand if you or a family member has known tree nut allergies

For households with no allergy concerns, returning the product is still recommended. There's no reason to keep a mislabeled food item, and Costco's full-refund policy means you lose nothing by doing so.

How to Stay Informed About Future Recalls

Food recalls happen more frequently than most consumers realize. The good news is that staying informed is easier than ever. Here are some reliable ways to monitor for active recalls:

• FDA Recalls Database: The U.S. Food and Drug Administration maintains a public database of all active food, drug, and cosmetic recalls at fda.gov
• USDA FSIS Alerts: For meat, poultry, and egg products, the USDA Food Safety and Inspection Service posts recall notices at fsis.usda.gov
• Costco Member Notifications: Ensure your Costco account email is current — the warehouse chain proactively contacts affected members when recalls occur
• Recall tracking apps: Apps like food safety recall apps can send push notifications when products you've purchased are recalled
• Bookmarking news sources: Outlets like USA Today, MassLive, and MSN regularly cover recall alerts with actionable detail

Pro tip: If you shop at membership-based retailers like Costco, your purchase history is already tracked — which means the retailer can and often will contact you directly if something you bought is recalled. Keep your contact information up to date in your account.
