Crawfish and seafood labeling; authorize enforcing agencies to receive and investigate complaints of noncompliance from any person.

HB 661 requires seafood and crawfish businesses (like restaurants, retailers, and processors) to clearly label products as "domestic" or "imported" based on their country of origin. It allows any person to file complaints with Mississippi's Agriculture and Marine Resources departments about mislabeling, which the agencies must then investigate. Businesses violating the labeling rules face fines starting at $500 for first offenses, increasing to $5,000 for third violations. The bill aims to ensure consumers receive accurate information about seafood origins through enforceable labeling standards and accessible complaint mechanisms.
