Summary

The effects of high-intensity pulsed-light emissions of high or low UV content on the survival of predetermined populations of Listeria monocytogenes, Escherichia coli, Salmonella enteritidis, Pseudomonas aeruginosa, Bacillus cereus, and Staphylococcus aureus were investigated. This study has shown that a 6-log10 reduction in microbial populations was achieved after exposure to 200 pulses of light containing high-intensity UV. The energy delivery system has modest energy requirements, and if this is delivered in a short period of time, with a high repetition rate, then rapid treatment can be achieved.
