A laboratory study has provided new insights into the efficacy of peroxyacetic acid (PAA) and chlorine dioxide against Escherichia coli, Listeria monocytogenes, and norovirus in wash water during potato processing, and investigated cross-contamination risks in batch washing and water reuse scenarios.
Biocidal chemicals and other physical/chemical techniques may be used together, in a strategic manner, to achieve an overall improvement in plant hygiene
Part 2 of this series examines a number of other interventions for food plant decontamination including light-based and reactive oxygen-based technologies, as well as peroxide, chlorine dioxide, ozone, and electrolyzed oxidizing water.
An interview with Mabel Gil, Ph.D., a senior researcher in the Food Science and Technology Department at the Spanish National Research Council, describes the use of chlorine dioxide as a chemical disinfectant for fresh produce and its applications for the juice industry.
