S. Typhimurium is one of the most dangerous microorganisms causing serious intestinal disorders of humans. It can be found in all types of foods such as meats, vegetables, fruits and beverages. The reduction or elimination of contaminated foodborne pathogens including S. Typhimurium in foods is commonly achieved by using chemical food preservatives. Concerns on the health risks of chemical preservatives have lead to the search of natural and safe antimicrobial agents. Since some bacteriophages have been approved by the USFDA as safe for use in foods, they are considered to be potential candidates for use as biocontrol agents in foods. Our study demonstrates the usefulness of the virulent bacteriophage ST1 for biocontrol of Salmonella Typhimuriumin in beverages.
