Popis: Growth-inhibitory activity of sodium chlorite (NaClO2) against food poisoning bacteria, such as Salmonella, Vibrio and Campylobacter spp., in bouillon were investigated and compared with those of NaClO and ClO2. The minimum inhibitory concentrations of NaClO2 and NaClO against Salmonella and Vibrio spp. at pH 7.0 were 400ppm, whereas those at pH 5.0 were 50 and 200ppm, respectively. Thus, in weak acidic medium, the inhibitory activity of NaClO2 on these strains was higher than that of NaClO. The inhibitory concentrations of NaClO2 and NaClO against Campylobacter spp. were 25-50 and 400ppm, respectively, at both pHs. However, ClO2 showed the same growth-inhibitory activity against those strains at only half the concentration of NaClO2.
