The SHRIMP Act of 2026 directs the Secretary of Commerce to develop a scientific method for determining where shrimp originates, with the goal of combating illegal fishing and improving food safety and traceability. The Secretary, working with U.S. Customs and Border Protection and the Coast Guard, must complete this methodology within 18 months and deliver a report within two years describing how it will be put into practice. The methodology must use chemical analysis, work quickly, and be portable enough to fit in a field kit that one person can carry, while being able to test raw shrimp, cooked shrimp, and prepared foods containing shrimp. The bill affects shrimp importers, domestic shrimp producers, and seafood retailers, as well as federal and state law enforcement agencies working to stop illegal fishing and enforce trade restrictions. No specific funding amounts are mentioned in the legislation.
