Ecuadorian shrimp producers insist that recent discoveries of COVID-19 on outer packaging containing their products shipped to China must have come from contact with external sources as they pass through a long chain of custody en-route to their final destination.

Chinese customs authorities suspended shrimp imports from three Ecuadorian producers, Santa Priscila, Empacreci and Edpacif on July 10 after allegedly detecting traces of COVID-19 among some recent shipments.
