Seasonal effect on L. monocytogenes prevalence in meat and dairy products assessed by VIDAS LMO2 and ISO 11290:1 methods

Kevenk T. O., . and Koluman A., . Seasonal effect on L. monocytogenes prevalence in meat and dairy products assessed by VIDAS LMO2 and ISO 11290:1 methods. pp. 929-936. ISSN 22317546

In the present work the seasonal distribution of L. monocytogenes in frequently consumed foods in the Aksaray region an important transition point was investigated by cultural and automated methods (ISO 11290 and VIDAS LMO2). For this purpose a total of 800 food samples (100 samples of each white kashar cream and Tulum cheeses and beef lamb chicken and turkey meats) were analysed. Listeria spp. were detected in 64 (8) samples and 177 suspected Listeria colonies were isolated. Of the 177 suspected colonies 71 were identified as L. monocytogenes by the ISO 11290 and VIDAS LMO2 methods. The pathogen was detected from samples purchased during winter spring summer and autumn at the rates of 3.7 3 26 and 3.6 respectively; the highest isolation rate was found in summer while the lowest isolation rate found in spring. Although the contamination of L. monocytogenes was found at the highest rate in summer it has been revealed that there was a risk of listeriosis which was not low throughout the entire year. We believe that compliance with standards such as HACCP ISO 22000 or GMP will be crucial in reducing the risk of listeriosis.

Abstract

In the present work the seasonal distribution of L. monocytogenes in frequently consumed foods in the Aksaray region an important transition point was investigated by cultural and automated methods (ISO 11290 and VIDAS LMO2). For this purpose a total of 800 food samples (100 samples of each white kashar cream and Tulum cheeses and beef lamb chicken and turkey meats) were analysed. Listeria spp. were detected in 64 (8) samples and 177 suspected Listeria colonies were isolated. Of the 177 suspected colonies 71 were identified as L. monocytogenes by the ISO 11290 and VIDAS LMO2 methods. The pathogen was detected from samples purchased during winter spring summer and autumn at the rates of 3.7 3 26 and 3.6 respectively; the highest isolation rate was found in summer while the lowest isolation rate found in spring. Although the contamination of L. monocytogenes was found at the highest rate in summer it has been revealed that there was a risk of listeriosis which was not low throughout the entire year. We believe that compliance with standards such as HACCP ISO 22000 or GMP will be crucial in reducing the risk of listeriosis.
