The objective of this study was to investigate microbiological, serological and parasitological quality in cig kofte (raw meatball) and their lettuce consumed in Istanbul. Consequently, a total of 102 cig kofte and 60 lettuce samples were analyzed for total mesophylic aerobic bacteria (TMAB), sulphite-reducing bacteria, coliforms, Escherichia coli, Bacillus cereus, Staphylococcus aureus, Staphylococcus-Micrococcus, and Salmonella spp. levels. Sulphite-reducing bacteria were not isolated from any of the samples. Salmonella were found positive in 9 of cig kofte and in 5 of lettuce samples. None of the analyzed samples was found to contain pork. Ten of them contained equine, 5 contained beef+mutton, 12 contained beef+poultry and 7 contained equine+poultry, while 68 of the 102 samples were only beef meat. Parasites and their fragments were also observed in some of the cig kofte and lettuce samples (6 insect fragments in cig kofte samples and 2 insect fragments, 5 acarus and mites and 2 Entamoeba coli + acarus in lettuce samples). It was concluded that cig kofte and lettuce offered to consumers in Istanbul have low microbiological and parasitological quality. Due to imitation of the products, unfair competition and profit is provided and consequently the safety of the consumer is at risk.

The effect of chitosan in combination with polyphenol oxidase (PPO) inhibitors and other additives (citric acid, rosemary extract) to inhibit or slow down melanosis during chilled and frozen storage was investigated. Fresh deepwater pink shrimps (Parapenaeus longirostris) were dipped in different solutions containing combinations of sodium metabisulphite (2500 mg/L), 4-hexylresorcinol (50 mg/L), chitosan (5 g/L), citric acid (200 mg/L) and rosemary extract (50 mg/L) and stored at 4°C for six days and at –18°C for twelve months. During storage, changes in colour were defined sensorially and instrumentally. Chitosan alone showed no effect on discoloration, but in combination with PPO inhibitors showed an additional inhibitory effect on melanosis formation. No noticeable darkening was observed during frozen storage in all treated shrimps, whereas signs of blackening were noticeable from the third month; 50 mg/L of 4-hexylresorcinol were more effective than 2500 mg/L of sodium metabisulphite in the prevention of melanosis development after shrimping.

The present study was conducted to investigate the incidence of Salmonella spp., Listeria monocytogenes and Escherichia coli O157 in 340 samples of meat and meat products (205 ground beef, 50 raw beef and 85 sausages) collected from producers and retailers in Istanbul. Salmonella spp. and Escherichia coli O157 analyses were performed acoording to ISO standarts, while Listeria monocytogenes was confirmed according to FDA methods. Salmonella spp. was detected in 1.18% samples. All samples were negative for L. monocytogenes and E. coli O157. The results indicate that meat and meat products may be contaminated by pathogens which can cause serious public health problems. Furthermore, the essential precautions should be undertaken to ensure improving the quality of production technology.
