Costco Tuna Poke Recalled for Potentially Containing Life-Threatening Bacteria

More than 3,000 lbs. of a ready-to-eat Costco meal have been recalled over concerns of contamination with a potentially life-threatening bacteria.

Supplier Annasea Foods Group has recalled 3,314.7 lbs. of Ahi Tuna Wasabi Poke from Costco’s Kirkland Signature brand after green onions used in the poke product tested positive for Listeria monocytogenes, according to a memo from the U.S. Food and Drug Administration (FDA).

The recalled ready-to-eat poke is found in Costco’s deli section, and is “packaged in clear plastic clamshell containers” with a Kirkland Signature brand label, according to the FDA. It has packing and sell-by dates of Sept. 18, 2025, and Sept. 22, 2025, respectively.

The affected seafood products were sold across 33 states nationwide.

The full list, as shared by the FDA, includes: Alabama, Alaska, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Indiana, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Washington and Wisconsin.

No illnesses have been reported to date, according to the FDA memo, which was publicized on Saturday, Sept. 20.

Supplier Annasea Foods Group said in the memo that the recall was issued after the company’s green onion supplier informed them that green onions “used only” in Ahi Tuna Wasabi Poke on Sept. 17 had tested positive for Listeria monocytogenes.

“We are continuing to work with our green onion supplier to determine the root cause,” the company said.

Listeria monocytogenes is “a type of disease-causing bacteria that can be found in many places, including soil, water, sewage, rotting vegetation and animals,” and “can survive and grow even under refrigeration,” according to the FDA.

When individuals consume food contaminated with the bacteria, they can develop listeriosis, with symptoms varying in severity. Symptoms on the milder side include “fever, muscle aches, nausea, vomiting and diarrhea,” which may persist for one to three days, per the FDA website.

“For the more severe, life-threatening invasive form of the disease, symptoms may include headache, stiff neck, confusion, loss of balance and convulsions,” the agency says. “Invasive listeriosis is a potentially life-threatening event, especially for newborns, adults over the age of 65, and those with weakened immune systems.”

Costco customers who have already purchased the recalled poke product are advised to not consume the item. Instead, they should “dispose of it immediately and visit your local Costco for a full refund,” the memo states.

For consumers who have already ingested the product and suspect they have developed symptoms resembling a listeriosis infection, the FDA advises contacting a healthcare provider.
