Résumé

Because of the public health significance of L. monocytogenes, US regulatory agencies established a policy whereby ready-to-eat foods contaminated with the organism at a delectable level are deemed adulterated. This "zero tolerance" policy makes no distinction between foods contaminated at high and low levels. A survey of over 31 000 ready-to-eat retail food samples showed an overall prevalence rate of 1.82%. In this study, the authors used the food survey data along with concurrent data regarding illness in the population consuming the foods, together with other variable factors, to derive a dose-response model. A microbial risk assessment based on the model show that a management strategy focusing on the concentration of L. monocytogenes rather than its presence alone may have a greater impact on the improvement of public health by facilitating the development of control measures to limit the maximum levels of L. monocytogenes in foods.
