In recent years, there has been a revived interest in their practical application because of the antimicrobial resistance crisis. One growing commercial application of bacteriophages is animal farming and food processing to reduce the risk of pathogens passing through the food chain into humans. The use of bacteriophages may help reduce the risk of contamination of the food chain with bacteria resistant to antibiotics, among which\n                        <jats:italic toggle=\"yes\">Salmonella<\/jats:italic>\n                        is recognized as a high concern pathogen for public health.
