Development of PCR-Based Technique for Checking Authenticity of Fish Fillets Supplied in Tabriz (Iran)

Abstract

Increasing consumer demand for seafood, combined with concern over the health of our oceans, has led to many initiatives aimed at tackling destructive fishing practices and promoting the sustainability of fisheries. So, our aim was to develop a PCR-based technique for checking authenticity of fish fillets supplied in Tabriz (Iran). In present study, about 80 samples of frozen fish fillet with general trademarks including south fillet, excellent fillet and 40 samples of Javelin grunter fillet and Scomberomorus commerson fillets were collected from different chain markets all over the Tabriz. Lot Tolerance Per-cent Defective (LTPD) method was used in collecting the samples which is the low errors. Our research showed a higher rate of misbrandingand misla-beling found in markets with general names (85%) and specified names of Javelin grunter and Scomberomorus commerson (40%). Based on present study, the capacity of shark is high in mislabeling and fraud because of their situation in making steaks and fillet, low price in compared with other spe-cies and religious limitations.
