Determination of the utility of ultraviolet-C irradiation for dried bay leaves microbial decontamination through safety and quality evaluations

This study was conducted to determine the efficacy of UV-C irradiation for safety and quality of dried bay leaves. Cocktails of microorganisms of the same species were prepared and inoculated onto the leaves, which were thereafter subjected to UV-C irradiation. Results showed that all tested organisms, which included Escherichia coli O157:H7, Salmonella enterica, Pseudomonas aeruginosa, Listeria monocytogenes, and Staphylococcus aureus,...
