Abstract
Bacteriophages are measurable components of the natural microflora in the food production continuum from the farm to the retail outlet. Phages are remarkably stable in these environments and are readily recovered from soil, sewage, water, farm and processing plant effluents, feces, and retail foods. Purified high-titer phage lysates have been used for the species-specific control of bacteria during the pre- and postharvest phases of food production and storage. For example, the inhibition of the phytopathogens Erwinia amylovara and Xanthomonas campestris has reduced the incidence of diseases such as fire blight in apples and bacterial spot of tomato and peaches. Research on preslaughter treatment of food animals has demonstrated phage control of salmonellosis in chickens, enteropathogenic Escherichia coli infections in calves, piglets, and lambs, and E. coli O157:H7 shedding by beef cattle. Phages have also been applied to control the growth of pathogens such as Listeria monocytogenes, Salmonella, and Cam...
