How to Determine the Geographical Origin of Seafood?
Traceability of seafood is a much needed service for the seafood industry. Current ways of tracing seafood are minimal while tracing of shellfish is nearly nonexistent. Tracing fish and shellfish are necessary for indicating where the fish and shellfish were fished from, farmed and packed from. This study reviews history of traceability of aquaculture and analytical approaches to verify the origin of seafood. It then describes the new molecular technique of the traceability by using PCR-DGGE to discriminate the geographical origin of fish (cases studies of Pangasius fish from Viet Nam and Sea bass fish from France) by analysis the DNA fragments of microorganisms (bacteria) on fish. This method is based on the assumption that the microbial communities of food are specific to a geographic area.
