Remember a few weeks ago we showed a video from the Boston Globe highlighting fish order fraud?
Turns out restaurants are soon turning to DNA tests to make sure that they're getting exactly what they ordered.
Last month, the FDA approved DNA barcoding to help restaurants and consumers guarantee that the fish is labeled correctly and they're not being sold a cheaper lookalike. It works as you might expect-a short DNA sequence is used to generate a barcode, which is then matched to a database of various species' DNA. The Consortium for the Barcode of Life has been using the technology in research projects to prove that the technology works, and now the FDA has approved its use in private industry, too.
