Abstract The abuse of antibiotics and the emergence of drug‐resistant bacteria aggravate the problem of food safety. Finding safe and efficient antibiotic substitutes is an inevitable demand for ensuring the safety of animal‐derived food. Bacteriophages are a kind of virus that can infect bacteria, fungi or actinomycetes. They have advantages of simple structure, strong specificity and nontoxic side effects for the human body. Bacteriophages can not only differentiate live cells from dead ones but also detect bacteria in a viable but nonculturable state. These characteristics make bacteriophages more and more widely used in the food industry. This paper describes the concept and characteristics of bacteriophages, and introduces the application of bacteriophages in preharvest production, food processing, storage and sales. Several methods of using bacteriophages to detect foodborne pathogens are listed. Finally, the advantages and limitations of bacteriophages in the food industry are summarized, and the application prospect of bacteriophages in the food industry is discussed.
