Risk assessment of Listeria monocytogenes in deli meats and vegetable salads / 中华预防医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analysis risk from Listeria monocytogenes in deli meats and vegetable salads.</p><p><b>METHODS</b>Use Risk Ranger which is a software programme developed by the University of Hobart, Australia and answer 11 questions on affecting the risk from hazards in the specific foods by combining data from national foodborne diseases surveillance network and some references to make semi-quantitative risk assessment for the specific food.</p><p><b>RESULTS</b>Relative risk from Listeria monocytogenes in deli meats and vegetable salads is 61 and 52, respectively. Incidence of listeriosis caused by deli meats-Listeria monocytogenes pairs and vegetable salads-Listeria monocytogenes pairs is 5.4 and 0.2 cases per million people, respectively. Risk from the former is 32 times than that from the latter. By changing the selection for some risk factors in the model, it was known that the risks from two food-hazard combinations could decrease 10 times, if taking necessary actions after processing.</p><p><b>CONCLUSION</b>Deli meats is a kind of high risk food for listeriosis.</p>
