Antibacterial effects of vinegar N6 and UV-C light-emitting diodes against Shiga toxin-producing and enterohemorrhagic Escherichia coli in fresh beef.

ABSTRACT: Some Escherichia coli serotypes cause diarrhea in infants and acute gastroenteritis. In this study, the incidence of Shiga toxin-producing (STEC) and enterohemorrhagic (EHEC) E. coli in 310 fresh raw beef samples and the presence of pathogenicity-associated virulence genes in the isolated strains were evaluated. The contamination rate reached 18.06% (STEC, 12.26%; EHEC, 5.81%). The highest rate of identified virulence genes was 8.38% for stx₂ and 3.23% for stx₂ and eae in STEC and EHEC, respectively. Vinegar N6 significantly lowered E. coli growth in beef samples, depending on its concentration (> 0.5%), treatment temperature (5 or 10 °C), and E. coli type (STEC, EHEC, or enteropathogenic), during 28 days of storage.
