November 30, 2016 — A new, faster seafood DNA testing technology could be developed by late next year, thanks to research starting soon in the United States.
J. Aquiles Sanchez, a senior research scientist at Brandeis University in Waltham, Massachusetts, U.S.A., will test and develop a “fast, cost-effective identification of edible fish and fish products to prevent species substitution and fraud,” according to the Seafood Industry Research Fund (SIRF), which is funding the project.
The research seeks to develop a rapid means of seafood species identification using Closed-Tube DNA Bar Coding. Compared to difficult and expensive DNA testing that the Food and Drug Administration uses currently, the closed-DNA system “represents a convenient alternative that can be used with both laboratory equipment and, importantly, handheld devices,” SIRF said in a statement.
“It is being developed for commercial use throughout the seafood supply chain. We know it will be less than the cost of laboratory DNA testing and results are much quicker than sending to a lab and waiting for those results. Speed is critical to the potential to use this technology to prevent mislabeling of fish species,” Russ Mentzer, chairman of SIRF, told SeafoodSource.
However, Baltimore, Maryland, U.S.A.-based InstantLabs already offers rapid DNA tests for several seafood species, including Atlantic, sockeye and coho salmon, Atlantic blue crab and catfish.
