Tuna sold in 26 states and in Washington, D.C., was recalled over concerns that it may have been contaminated. The stores affected include Trader Joe’s, Genova, Van Camp’s and H-E-B.

A canned tuna recall at Costco and other stores over a botulism risk has consumers on alert. Check if your tuna is affected and what to do next.

The company said that the easy-pull can lid “encountered a manufacturing defect that may compromise the integrity of the product seal (especially over time), causing it to leak or worse, be contaminated with Clostridium botulinum, a potentially fatal form of food poisoning.”
