Abstract

We investigated strategies to reduce Listeria monocytogenes contamination on food contact surfaces during enoki mushroom processing. Chemical disinfectants and thermal treatments were evaluated on conveyor belts, stainless steel, plastic surfaces, and Velcro strips. Without organic matter, chemical disinfectants effectively reduced L. monocytogenes, with stainless steel showing the highest susceptibility. Organic matter decreased disinfectant efficacy, but sodium hypochlorite remained most effective on stainless steel. Peracetic acid was more effective on conveyor belts and plastic surfaces than on stainless steel. Combining peracetic acid with dry heating synergistically reduced L. monocytogenes on Velcro strips. Moist heat at 70 °C alone was insufficient, but when combined with hot air drying, it effectively reduced L. monocytogenes on Velcro strips. Our findings emphasize the importance of surface-specific strategies combining chemical disinfection and thermal treatment for eliminating L. monocytogenes in mushroom processing environments.

期刊介绍： The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
