INVESTIGATION OF LISTERIA MONOCYTOGENES IN THE FISH RETAIL SALES AREA
Project no. 1052 · Status: Kapanmış · 2017
Summary
Listeria monocytogenes is an important food-borne pathogen and is widely found in nature. Many industrialized countries are concerned about the presence of this pathogen in food, especially in ready-to-eat foods. Seafood is also among food sources that can contain L. monocytogenes. In this study, the presence of L. monocytogenes was investigated by collecting samples from fresh or cooked (ready-to-eat) products in different aquaculture retail areas. The samples were collected from four different samples (bench, employees' hands, cleaned and cooked seafood) in three different retail areas, one in autumn, winter, spring and summer seasons. The presence of L. monocytogenes was investigated in the samples brought to the microbiology laboratory and, if detected, the species was confirmed. There was no intense L. monicytogenes in the samples. In the autumn samples, in two of the three enterprises, samples taken by swap method from the cleaning bench were; 2.1 LogKOB / 100cm2 and 1.2 LogKOB / 100cm2 L. monicytogenes were detected. However, L. monocytogenes was not detected in samples taken from cleaned (prepared for cooking / sale) seafood and samples from cooked (ready for consumption) seafood. L. monocytogenes could not be detected in winter, spring and summer samples.
