Abstract

Bactericidal strength of electrochemically activated solution “Supowa” (superoxidizing water) was investigated using E. coli (ATCC®14169™), S. aureus

(ATCC®25923™), Salmonella (ATCC®25241™) and L. monocytogenes (ATCC®7644™) as model bacteria. Bateria in an 0.1 % peptone solution with a concentration of 108 CFU/ml were completely inactivated after 2 min exposure with Supowa solution (50 mg/l active chlorine). Surface treatment of inoxidable table and plastic basket with Supowa solution resulted in a quite better disinfection efficacy (p < 0.05) compared to the use of conventional disinfectant calcium

hypochlorite. Treatment of raw octopus material using Supowa solution showed that its disinfecting efficacy was less manifested and slightly greater than the case of conventional disinfectant (p > 0.05). Supowa solution can be used as a disinfectant for reducing bacteria on contacting surfaces and raw octopus materialsat seafood processing lines.
