TWO strains of V parahaemolyticus T‐3765‐l and SB04‐422, were exposed to chlorine and iodophor solutions (laboratory and commercial). The effectiveness of both the chlorine and iodophor treatments was enhanced under acidic conditions. At 20°C and pH 7, the effectiveness of the iodophor was similar to that of chlorine in the destruction of V. parahaemolyticus. The iodophors were superior to chlorine in the destruction of V. parahaemolyticus at 0°C. In general, the prior growth temperature of the organism had little effect on its subsequent survival in either the laboratory iodophor or the chlorine solutions. In a simulated oyster blowing process, the iodophor again proved to be a more effective bactericidal agent than chlorine, and sensory evaluation of oysters exposed to the iodophor solution showed that there was no odor problem associated with such a treatment.
