Review and Analysis of Tuna Recalls in the United States, 2002 through 2020

This review covers 18 years of voluntary recalls of tuna sold commercially in the United States. Recall information is a valuable indicator of failure to implement procedures for food safety. The voluntary recalls involve tuna that was fresh, frozen, processed, hermetically sealed, retorted in a shelf-stable pack (i.e., canned), and formulated into other tuna products. U.S. Food and Drug Administration regulations address the capture, processing, transportation, and sale of raw and processed seafood. These regulations include current good manufacturing practices, the Food Modernization Act, emergency permit controls, and guidelines for low-acid canned foods, seafood hazard analysis and critical control points, food labeling, and sanitary food transportation. Traceability and the food safety culture are important for successfully preventing or implementing recalls. The recalls themselves were separated into product treatment groups: uncooked products, canned shelf-stable products, and products in which tuna was used as an ingredient. The recalls were further categorized and summarized by reason or cause, such as biological and chemical contamination, undeclared ingredients, underprocessing, and foreign materials. The primary causes of recalls of the reviewed tuna products were (in order) Listeria monocytogenes, undeclared allergens, elevated histamine concentrations, and underprocessing of retorted tuna products. The recalls for elevated histamine concentrations primarily affected uncooked (raw) tuna. Recalls for Listeria contamination and the presence of undeclared allergens were primarily class I recalls, and recalls for elevated histamine concentrations and underprocessing were almost always assigned to the less serious recall class II.
