| Popis: | Gaseous chlorine dioxide, a strong oxidizing agent can be utilized as an effective alternative sanitizing agent. This study evaluated the efficacy of low concentration (≤5 mg/L) gaseous chlorine dioxide (ClO₂) treatment with gas permeable sachets in reducing the levels of Salmonella, E. coli O157:H7, and Listeria monocytogenes on strawberries and blueberries. Strawberries and blueberries were spot inoculated (107 CFU/g) with multi-strain cocktails of each pathogen and dried for 120 min inside a biosafety cabinet. A treatment chamber was successfully designed to sanitize inoculated samples in sealed 5 gallon chambers containing gaseous ClO₂ sachets. The gaseous ClO₂ overhead concentration was maintained within the range of 3.32 ± 1.73 to 4.95 ± 2.19 mg/L for up to 3 h of treatment. Gaseous ClO₂ treatments reduced pathogen levels significantly (P |
