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.

Trader Joe's, Costco, and Walmart are among the retailers and brands caught up in the massive recall. Botulism is a rare but serious illness.

The recall was triggered by "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," the Food and Drug Administration ( FDA) said.
