A multiplex-polymerase chain reaction (PCR) system was developed for the authentication of the mackerel Scomber colias in commercial canned products. This novel method consists of an S. colias-specific fragment [159 base pairs (bp)] located in the nontranscribed spacer (NTS) sequence, and a Scomber genus-specific PCR product in the 5S rRNA gene (196-201 bp) as a positive amplification control. The system was assayed using 18 different canned products labeled as S. colias. A positive identification was made in all but one sample, revealing this methodology as a potential molecular tool for direct application in the authentication of S. colias canned products.
