by Issaquah, WA – Costco has announced the recall of over 3,300 pounds of Kirkland Signature Ahi Tuna Wasabi Poke due to a potential listeria monocytogenes contamination linked to the green onions used in the product.

This urgent recall affects poke packaged and sold at various Costco Warehouse deli sections across 33 states on September 18, 2025. No illnesses have been reported so far, but health officials urge consumers to take immediate precautions.
How the Listeria Contamination Was Identified

“We are continuing to work with our green onion supplier to determine the root cause.”
This proactive approach is critical to preventing further distribution of potentially contaminated products.
