This study aimed at comparing the inhibitory effects of various decontamination agents (1% lactic acid, 2% lactic acid, 2% acetic acid, 0.1% acidified sodium chloride, 0.1% sodium acetate, and 0.1% cetylpridinium chlorine) on experimentally contaminated raw beef samples with Listeria monocytogenes being a significant pathogen microorganism for public health. The highest level of bacterial inhibition was determined in the meat samples treated with 2% lactic acid while the lowest level was in the samples treated with 0.1% acidified sodium chloride. It is very important to specify that initial bacterial load of carcases, the decontamination technique applied, and the characteristics of acids used (dissociated or undissociated, pH, amount, percentage, application temperature, and different combinations) are essential parameters to be taken into account in the process of reducing microorganism on raw meat samples.

Seafood are an ideal animal products as adequate and balanced nutrition for human. However, fish affected by environmental pollution maybe transfer the harmful effects of pollution to humans at the end of the food chain. Bafa Lake has been frequently mentioned with the environmental pollution problems in recent years. In this study, the accumulation of copper (Cu), zinc (Zn), iron (Fe), cadmium (Cd), and lead (Pb) heavy metal elements were investigated in the fillet, gonad, liver, and gills of grey mullet fish, which is one of the most caught fish species from Bafa Lake. According to the results obtained, more element concentration levels were determined in the liver and gills than ones in the muscle tissue. Cu concentration was ranked according to tissues, liver ˃ gill > gonad ˃ fillet form; Zn amount, liver ˃ gonad ˃ gill ˃ fillet form; Fe amount, liver ˃ gill ˃ gonad ˃ fillet shaped; Cd amount, liver ˃ filet ˃ gill ˃ gonad. The amount of Pb was found in the form of gonat ˃ liver ˃ filet ˃ gill. It was determined that 16% Cd and 68% Pb out of all the muscle tissue in the samples had above the consumable limit respectively. So, these results are a very risky situation for public health. In order to prevent environmental pollution in Bafa Lake and its harmful effects on humans and other living things, it should not be disconnected from the Meander (Büyük Menderes) River, industrial discharges to be made in the Meander River should be done after treatment, and basin management should always be at the forefront in the development works around the lake.
