Food safety means that food is non-toxic and harmless, meets the nutritional requirements, and will not cause any acute, subacute or chronic harm to human health. According to the definition of the World Health Organization, food safety is "a public health problem in which toxic and harmful substances in food affect human health". Food safety is also an interdisciplinary field, focusing on ensuring food hygiene and food safety, reducing hidden diseases and preventing food poisoning in the process of food processing, storage and sales.

At present, the meaning of food safety has three levels:

First, the quantity of food is safe: that is, a country or region can produce the dietary needs needed by the basic survival of the nation. People are required to be able to afford the basic food needed for survival and life.

2. Food quality and safety: refers to the food provided to meet and protect people's health needs in nutrition and hygiene. Food quality and safety involves food pollution, whether it is toxic, whether additives are illegal, and whether labels are standardized. It is necessary to take measures before food is contaminated to prevent food pollution and major harm.

Third, sustainable food safety: This requires that the acquisition of food should proceed from the perspective of development, and pay attention to the good protection of the ecological environment and the sustainable utilization of resources.
