The aim of the study was to examine the effects of gamma irradiation on the microbiological and physio-chemical characteristics of meatballs. Meatball samples were produced experimentally and divided into six subgroups. The first group (control group) was not subjected to an irradiation process, and the remaining groups were subjected to irradiation at doses of 1, 2, 3, 5 and 7 kGy. All groups were analyzed on days 0 (the day of irradiation process), 5, 10, 15, 20 and 30. The study revealed a significant reduction in the microbiological flora of the meatballs in relation to gradual increases in irradiation dosage. Faecal coliform bacteria counts, coliform bacteria counts and S. aureus counts were eliminated after applying 2 kGy, 3 kGy and 7 kGy irradiation doses, respectively. During storage at 4±1 °C, the bacterial populations systematically increased. Compared to the control group, low dose irradiation did not significantly change pH values, but higher pH levels were determined during high doses of irradiation. Irradiation increased the peroxide levels, but this increase did not seem to correlate with irradiation dosage. FFA levels decreased in relation to increasing levels of irradiation dosage.

The aim of the study was to investigate the prevalence of Salmonella spp. L. monocytogenes, E. coli 0157:H7 in chicken carcasses and their products (legs, wings, breast meat and giblets) and their microbiological quality. Samples were evaluated for total aerobic mesophilic bacteria, psycrofils, enterobacteriaceae, coliform, Escherichia coli, Staphylococcus-Micrococcus, Staphylococcus aureus, mould and yeast, and Yersinia enterocolitica counts. Salmonella spp., L. monocytogenes and E. coli 0157:H7 were isolated in 18.4%, 9.6% and 4.8% of the samples, respectively. The highest contamination levels of these bacteria were 48%, 24% and 20% in chicken breast meat, and the lowest: 8%, 0% and 0% in legs, respectively. E. coli was found in all samples and S. aureus was found in 65% of the samples. The results of the study indicate that chicken carcasses and their products may contain significant hazards to humans and are a danger to public health.

Turkish fermented sausages are one of the commonly consumed meat products in Turkey. In this study the effects of low dose gamma irradiation (1, 2 and 3 kGy) on the microbiological quality properties of Turkish fermented sausages have been investigated. The numbers of total aerobic mesophilic bacteria, coliform, Staphylococcus aureus, mould, yeast, lactic acid bacteria, and sulphite reducing Clostridia were analyzed. In sausage samples it was determined the number of microorganisms decreased or were eliminated according to the increased doses of gamma irradiation. The dose of 1 kGy was sufficient to eliminate the yeasts and sulphite reducing Clostridia. Coliforms and moulds were reduced to under detectable values after the application of 2 kGy irradiation doses, Staphylococcus aureus and lactic acid bacteria by the application 3 kGy. It was concluded that the 2 kGy dose was sufficient to control bacterial population to maintain Turkish fermented sausages within designated standards for this product.

Escherichia coli O157 is one of the major threats to public health due to the consumption of meat and meat products. The microorganism is known as a food-borne pathogen even in the presence of low levels. Therefore, a more sensitive method is required to be used for the detection of the microorganism. Immunomagnetic separation (IMS) is a technique used to improve the sensitivity of the detection. IMS has been used to determine the presence of E. coli O157 in raw and cooked Doner samples in this study. 3 out of 30 raw Doner samples have been found to be contaminated with E. coli O157. None of the cooked samples were carrying the agent.
