The efficacy of gaseous Chlorine dioxide to reduce parasite and bacterial burden in produce was studied. Basil and lettuce leaves were inoculated with Cryptosporidium parvum and Cyclospora cayetanensis oocysts, Encephalitozoon intestinalis spores, and a cocktail of two isolates of nalidixic acid–resistant Escherichia coli O157:H7. The inoculated samples were then treated for 20 min with gaseous Chlorine dioxide at 4.1 mg/liter. Cryptosporidium had a 2.6 and 3.31 most-probable-number log reduction in basil and lettuce, respectively. Reduction of Encephalitozoon in basil and…

Chlorine dioxide (ClO2) is effective as both a disinfectant and an oxidant in water and wastewater treatment. Its selective reactivity makes Chlorine dioxide a powerful non-chlorinating oxidizing agent useful in many water treating applications for which Chlorine and other oxidizing agents are unsuitable. Unlike most oxidants, Chlorine dioxide may be used over a broad pH range to oxidize industrial odor causing compounds.
