The Effect of Satureja bachtiarica Bunge., Carum carvi L., and Thymus daenensis Čelak. Essential Oil on Cronobacter sakazakii, a Foodborne Opportunistic Pathogen

Cronobacter sakazakii is one of the main pathogens transmitted to infants through the consumption of contaminated infant formula and baby food. The bacterium is a major cause of mortality, digestive diseases, and meningitis in newborns. The present study was performed to determine the microbiological effect of C. Sakazakii in the infant formula and baby food samples and to investigate the effect of ۳ plant essential oils on bacterial isolates. A total of ۲۰۰ samples of baby food and infant formula of different brands were collected, and the inhibitory effects of bacterial growth by essential oils of Satureja bachtiarica, Carum carvi, and Thymus daenensis were evaluated by the disc diffusion method. The most sensitive bacteria isolated at ۱۰۰۰ micrograms per milliliter were T. daenensis, S. bachtiarica, and C. carvi, respectively. Inhibitory effects of growth were not observed in the concentration of ۳۱ micrograms per ml in any of the essential oils. Infection outbreaks caused by bacteria can be reduced by careful inspection of the quality of infant formula and baby food, strict supervision of the production process, adherence to hygiene rules, and the use of natural antimicrobials.
