A New York importer is recalling frozen fish after an inspection found that it might be contaminated with botulism-producing spores, the U.S. Food and Drug Administration announced Tuesday.

JFC International distributed the frozen capelin, a species of smelt, nationwide. The capelin is uneviscerated, meaning the digestive organs are intact, thus increasing the risk of contamination.

The capelin was imported from Vietnam and distributed on Styrofoam trays and wrapped in plastic wrap.
