The U.S. Food and Drug Administration (FDA) has issued a Class I recall—the agency's highest of three health-risk ratings—for Kirkland Signature brand Ahi Tuna Wasabi Poke sold at Costco locations across 37 states.
The voluntary recall, announced by Western United Fish Company on September 20, was prompted after Listeria monocytogenes contamination was detected in green onions used in the product, with federal officials urging consumers not to consume the affected tuna.
Approximately 3,314 pounds of the product have been affected.

Newsweek contacted the product's manufacturer, Western United Fish Company dba Annasea Foods Group, of Kent, Washington, via general email inquiry outside of regular office hours on Tuesday.
Why It Matters
The FDA's Class I status signifies a situation where there is a “reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death.”
Infections with Listeria monocytogenes can cause severe illness, particularly for young children, seniors, pregnant women, and individuals with weakened immune systems. According to the FDA, “Healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea; however, Listeria infection can cause miscarriages and stillbirths among pregnant women.”

Class II—a situation in which use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.
Class III—a situation in which use of, or exposure to, a violative product is not likely to cause adverse health consequences.
