A study was carried out on three different brands of cola which are marketed in Turkey. Liquid portions of the collected colas were fully removed at 55 oC Antibacterial effect spectrum was determined by Cut Plug method. Minimum Inhibitory Concentrations were determined by micro dilution method by preparing serial dilutions of cola on studied bacterial strains. It was found out that cola has a strong antibacterial effect on Bacillus Cereus, Enterococcus faecalis, Escherichia coli, Escherichia coli O: 157 H: 7, Salmonella enteritidis, Yersinia enterocolitica bacteria and antifungal effect of cola could not be identified. It was considered that cola drinks can be used for the treatment of bacterial factors and bacterial circles causing food toxicity. At the end of the study, a comparison could not be carried out as there was no study on the antibacterial effects of cola on various bacteria. It has been considered that cola beverages can be used for the treatment of bacterial factors and bacterial circles causing food toxicity.
