An insight into the applications of bacteriophages against food-borne pathogens

Abstract

Novel and emerging pathogens, enduring contamination, antibiotic resistance, an environment that is always changing, and the complexity of food production systems all contribute to the worsening of foodborne illness. It has been proposed that bacteriophages can serve as both fast food-borne pathogen detection tools and natural food preservatives in a variety of foods. Phages, like many other antimicrobial interventions used in food production systems, are not a cure-all for issues related to food safety, though. Consequently, phage-based biocontrol has a generally narrower antibacterial spectrum than most antibiotics, even though it can be promising in the fight against foodborne infections. Among the difficulties phage-based biocontrol techniques encounter are forming phage-insensitive single-cell variations and creating potent cocktails. To better understand when and where phage-based applications can be successfully implemented at the production and processing levels, this review focuses on phage-based applications at crucial control points in food production systems.
