Inadequate heating is a common cause of food poisoning in the restaurant industry. Food poisoning is caused by the human body ingesting contaminated or inadequately heated food, resulting in symptoms of discomfort or even poisoning. In the catering industry, many foods have to be heated before consumption. Inadequate heating or insufficient time will result in microorganisms, such as bacteria, viruses and parasites, not being killed, thus triggering food poisoning. When making food in the catering industry, it is important to pay attention to adequate heating to ensure that the food meets safety standards.
