A group of North American processors and trade groups are banding together to prevent shrimp harvested illegally by artisanal fishermen in Mexico from being "laundered" through Mexican processing plants along with legitimately caught products.

Shrimp harvested illegally using gillnets in protected inshore fisheries in bays or inlets pose a threat to the endangered vaquita porpoise. The US Court of International Trade last year ordered the Trump administration to ban seafood imports from Mexico caught with gillnets in which vaquita become entangled.
