AbstractListeria monocytogenes constitutes one of the major food borne diseases worldwide. One of the sources of Listeria monocytogenes infection in humans is the consumption of contaminated ready to eat (RTE) meat foods. The objective of the model was to determine concrete options to mitigate the risk of L.monocytogenes illness associated to the consumption of RTE meat-based foods. Based on the collected data, a Quantitative Microbial Risk Assessment model was built up. The model considered three main risk exposure pathways namely the consumption of bovine meat within the household, the consumption of bovine meat outside the home, as well as the consumption of goat meat (grilled goat brochettes) of Coimbatore city. According to the model, the risk of L.monocytogenes illness associated to the consumption of RTE meat based foods Coimbatore city inhabitants appeared to be relatively low (ranging from 1.7 to 3.4% depending of the risk exposure pathway) and was found to be increasing with the meat consumption level in different socio-economical category of the consumers. The analysis of risk mitigation scenario revealed that an efficient control of L.monocytogenes illness associated to the consumption of RTE meat based foods can be achieved through a simultaneous application of control measures at different levels of the meat chain, in particular at the preparation stage within households and collective catering establishments.
