Consumers who recently purchased fresh fish from specific Carrefour and Auchan locations are being warned to check their refrigerators immediately. Two separate recalls have been issued for vacuum-packed tuna and mackerel after tests revealed excessive levels of histamine, a compound that can trigger severe, allergy-like reactions even in individuals who have no known food allergies.
The alerts, coordinated through the official Rappel Conso platform, highlight a critical but often invisible food safety risk. Unlike bacterial contamination, which may cause a distinct foul odor or visible slime, histamine toxicity—often referred to as scombroid poisoning—does not typically alter the taste, smell, or appearance of the fish, making it impossible for consumers to detect the danger at home.
As a physician, I have seen how these reactions can be mistaken for sudden allergic shocks. The risk is particularly acute for those with existing respiratory sensitivities, for whom a high-histamine meal can escalate from a simple stomach upset to a medical emergency. Due to the fact that the toxin is heat-stable, cooking the fish—whether searing it or baking it—will not neutralize the histamine.
Carrefour Recall: Albacore Tuna in Louhans
The first recall specifically targets unbranded albacore tuna loins sold in vacuum-packed trays. This alert is localized to the Carrefour Market in Louhans, where the product was sold between March 26 and March 31, 2024.
Customers are urged to check their stock for the following identification details:
- Product: Albacore tuna loin (no brand)
- Packaging: Vacuum-packed tray
- GTIN: 201018048675
- Expiration Date (DLC): March 31, 2024
The product is being withdrawn due to histamine levels that exceed safety thresholds. Consumers who have this specific lot in their possession should not consume it. They may return the product to the Carrefour Market in Louhans for a full refund, a process that remains active until April 27, 2024. For further inquiries, the Carrefour consumer service is available at 0805 908 070.
Auchan Recall: Mackerel Fillets in Mérignac
Simultaneously, a separate alert has been issued for vacuum-packed mackerel fillets under the Auchan Le Poissonnier label. This recall is restricted to the Auchan Supermarché in Mérignac Robinson.
The recall covers all lots of these mackerel fillets purchased between March 17 and March 22, 2024. Similar to the tuna recall, these products must not be consumed. Customers are advised to return the fillets to the Mérignac Robinson store for a refund, with the return window open until May 7, 2024. A dedicated customer line has been established at 0556343710 to assist affected buyers.
Understanding Histamine Toxicity and Scombroid Poisoning
Histamine is a biogenic amine that forms naturally in certain fish species—particularly scombroid fish like tuna, mackerel, and mahi-mahi—when they are not kept at strictly controlled, low temperatures immediately after being caught. Bacteria start to break down the amino acid histidine into histamine.
When a person consumes fish with high histamine levels, they experience a “pseudo-allergic” reaction. Because histamine is the same chemical the body releases during an actual allergic reaction, the symptoms are nearly identical. These typically manifest within 30 minutes to a few hours after ingestion:
- Cutaneous: Intense flushing, redness of the skin, and swelling of the face or lips.
- Gastrointestinal: Nausea, vomiting, abdominal cramps, and diarrhea.
- Neurological: Sharp headaches and a sensation of warmth or “hot flashes.”
- Respiratory: In severe cases, especially for those with asthma or existing allergies, acute respiratory distress can occur.
If you suspect you have consumed contaminated fish and are experiencing difficulty breathing or significant swelling, you should seek immediate medical attention at an emergency department.
Safe Handling and Prevention
Whereas these recalls are the result of failures in the supply chain, consumers can minimize their own risks by adhering to strict cold-chain protocols. Once fish is purchased, it should be transported in insulated bags and refrigerated immediately. Because histamine is a result of temperature abuse, keeping fish at or below 4°C (40°F) is the primary defense against the development of these toxins.

Authorities continue to monitor the distribution chains for these lots to ensure all contaminated products are removed from shelves. The next phase of the process involves the final closure of the recall files once the refund deadlines have passed and the affected batches are confirmed destroyed.
