Vibrio parahaemolyticus is a typical marine bacterium, which often contaminates seafood and poses health risk to consumers. Some non-thermal sterilization technologies, such as ultrasonic field (UF) blue light (BL) irradiation, have been widely used in clinical practice due their efficiency, safety, avoidance of drug resistance, but application food preservation has not extensively studied. This study aims investigate the effect BL on V. culture media ready-to-eat fresh salmon, evaluate...
