Urgent recall issued for thousands of pounds worth of popular fish dish sold at Costco

An urgent recall has been issued for a popular fish dish sold exclusively at Costco over fears the product contains a potentially fatal bacteria. 

Shoppers across 33 states are being urged to take precautions around Western United Fish Company’s Kirkland Signature brand Ahi Tuna Wasabi Poke.

The ready-to-eat fish was recalled because the green onions mixed in potentially contain Listeria monocytogenes.

The bacteria can cause fever, vomiting, and diarrhea among other troubling issues.

The FDA issued the recall yesterday following a positive test for Listeria in the onions.

More than 3,000 pounds worth of the product was shipped to Costco warehouse across the US. 

The affected tuna is packaged in clear plastic clamshell containers and labeled with the Kirkland Signature brand and was sold in the deli section of the warehouse.

The products have a pack Date of 9/18/2025 and a sell by date of 9/22/2025.

No illnesses have been reported due to the possible contamination yet. 

Listeria can cause a wide range of symptoms, which may include muscle aches, nausea, fever, vomiting, and diarrhea. These symptoms often last between one and three days, according to the FDA.

However, more severe infections can cause convulsions, a stiff neck, confusion, and loss of balance.

It is particularly dangerous for young children, the elderly, those with a weakened immune system, and pregnant women.

For pregnant women, Listeria can lead to miscarriages or stillbirths.

Listeria is the third-most common food-related illness death in the US, after Salmonella and Toxoplasma gondii.

About 260 people die annually from the infection, according to the US Centers for Disease Control and Prevention estimates.

In 32 states across the US, approximately 3,314.7 pounds of the product were sent to Costco warehouses

Food processing facilities are one of the places where bacteria can be spread and contaminate food, according to the CDC.

Customers who purchased the products are asked not to eat them and return them to the store for a full refund.

Consumers are advised to watch for symptoms of listeriosis and seek medical attention if they experience any illness after consuming it.

The green onions were only used in the Ahi Tuna, according to the statement.

The Daily Mail has reached out to Annasea Foods Group which does business as Western United Fish Company and Costco for comment.

Last October, another incident with Listeria occurred for the company, involving thousands of pounds of fish.

Kirkland Signature smoked salmon was recalled due to the same issue, with a supplier warning that the salmon had tested positive for Listeria.
