Foodborne diseases affect millions of people each year. To reduce the incidence of bacterial foodborne pathogens, more effective treatment methods are needed. In this study, the authors have evaluated the effect of marinating chicken breast fillets with extracts of lemon, green tea and turmeric against Campylobacter jejuni and Salmonella enteritidis. The prepared plant extracts in phosphate buffered saline were added to chicken breast fillets both singly and in combination and were incubated at 4 degree Celsius. Cell counts were made at regular intervals and the viability percentage was calculated. A combination of green tea, lemon and turmeric was found to be the most effective against C. jejuni and S. enteritidis killing all the bacteria within 12 hrs of incubation, with a 5-log reduction in growth within 1 hr of incubation and proved to be more effective than any of the extracts used alone. Further, combinations of both lemon and green tea and lemon and turmeric killed all C. jejuni isolates, but not S. enteritidis, within 24 hrs of incubation.
