Abstract The distribution of pathogenic vibrios and other bacteria in eight samples of imported frozen shrimps and the effect of irradiation on these bacteria were investigated. Total aerobic bacteria were at 2×104 to 4×106/g. Coliforms consisted mainly ofEnterobacter. No salmonella were detected. A total of 66 isolates, includingVibrio parahaemolyticus, V. mimicus, V. alginolyticus, V. vulnificus, V. fluvialis and a few ofListeria monocytogenes, were obtained. The gamma-radiation dose needed to reduce by 10−4 the number of vibrio isolates andAeromonas hydrophila was about 3 kGy in frozen shrimps, whereas about 3.5 kGy was required forL. monocytogenes.
