Effect of gamma irradiation, high sugar content and antimicrobials on survival of Escherichia coli: A Review

Dried fruits are popular ready-to-eat snacks. However, due to cross-contamination or contact with infected persons, E. coli could be present, of which some strains pathogenic, thus, the consumption contaminated dried pose a public health risk. Microbial cells subjected stress factors such as osmotic shock, radiation and antimicrobials induce complex response systems adaptation. Radiation have been shown cause an SOS in coli, affects cellular metabolism, enhanced ability repair DNA mutagenesis. Studies that glucose plays critical role down- upregulation locus for enterocyte effacement (LEE)-encoded virulence coli. Gamma also formation viable but nonculturable (VBNC) cells. If these present sample, number will underestimated by plate count method leading false conclusion product is germ-free. We reviewed this article how stressors high sugar content, gamma radiation, affect survival fruits.
