Online tool screens finfish fillets for mislabelling, substitution Featured

NOAA Fisheries has formally rolled out a web-based screening tool that can flag potentially mislabelled finfish fillets before they hit the seafood aisle. Developed by the National Seafood Inspection Laboratory (NSIL), the Species Substitution & Protein Pattern Matching Tool could help the seafood industry address finfish substitution and fraud. To help maintain the nation’s safe, sustainable supply of seafood, researchers at NSIL developed a lab method and online screening tool that lab technicians can employ to compare finfish muscle proteins against NSIL’s Authenticated Finfish Species Library.

The tool quickly generates a list of species matches ranked from most to least likely-positioning it as a perfect precursor and complement to DNA testing programs. Wholesale and other buyers typically send their fillet samples to third-party labs for DNA analysis when they suspect species substitution. By first screening their samples for common substitutions with the Species Substitution & Protein Pattern Matching Tool, however, these buyers can save time and money, reserving DNA testing for instances when a probable mislabelling needs to be verified.

The US Food and Drug Administration and other regulatory labs currently using DNA testing could also fold NSIL’s tool into their procedures to screen a larger quantity of finfish fillets for common substitutions. The Species Substitution & Protein Pattern Matching Tool is one of many services and resources provided by NSIL. From their offices in Pascagoula, Mississippi, the NSIL team works cooperatively with federal and state agencies, international governments and organizations, and private industry to ensure the safety of seafood for US consumers.
