Suppressive Antimicrobial Treatment: Ozone/Water Spray for California Fresh Produce Processor

摘要

Aqueous sprays of Ozone treated water, 1.25 to 2.40 ppm were applied to various produce conveying surfaces for varying times. This treatment followed the fresh water rinse which is a routine first step in the daily plant clean up protocol. Aerobic Plate Counts of various sites sampled after the fresh water rinse but before the ozone/water treatments ranged between 5.7×10(4) cfu and 3.0×10(3) cfu. After the various treatments with ozone/water mixture Areobic Plate Counts ranged between 1.0×10(2) and <1.0×10(1) cfu. This paper discusses the methodology of ozone/water applications and practical uses for this ozone/water application.
