Food safety includes not only safe food production but also safe food consumption. Among the biological hazards, bacteria pose the greatest threat to food safety and cause food poisoning.
One of the biggest agents of food contamination in our homes is the cutting board. All plastic and wood cutting boards wear out over time. Cutting boards should be discarded if they create deep crevices that are difficult to clean and where microorganisms can colonize. According to a study, it has been determined that the biggest sources of contamination during preparation are personnel hands, used knives and cutting boards.
