In recent years, habit of eating ready foods has increased parallel to the increase in population. As a result of this catering has become an industry. However; not showing enough care to hygienic and technological conditions during production cause many problems related to public health. Thus, this study was performed to determine the possible risk in foods for public consumption and to take some precautions. According to this, 335 samples from 7 different groups of various catering firms were collected. They were analysed for coagulase positive Staphylococcus aureus. Salmonella spp. and Escherichia coli. As a result of the analyses, 62 of total 335 samples were (18.5%) found to contain Escherichia coli. From one of the samples, Salmonella spp. was isolated (0.29%). Coagulase positive Staphylococcus aureus was isolated in none of these samples. As a result of the evaluation of the findings, the presence of E.coli and Salmonella spp. indicated that hygiene and technology of catering in our country is not favourable and enough care is not given to these concepts.
