According to the definition of the World Health Organization, hotel food safety is "a public health problem in which toxic and harmful substances in food affect human health". Hotel food safety requires that all dangers of food causing acute or chronic damage to human health do not exist, which is an absolute concept. Hotel food safety is an interdisciplinary field, focusing on ensuring food hygiene and food safety, reducing hidden dangers of diseases and preventing food poisoning in the process of hotel food processing, storage and sales.
