FSIS LISTERIA RISK ASSESSMENT REPORT
SCOPE AND MANDATE
This risk assessment was initiated in February 2002 in response to public comments on the Food Safety and Inspection Service (FSIS) proposed rule: Performance Standards for the Production of Processed Meat and Poultry Products [66 FR 12589, February 27, 2001]. Several comments indicated a need for a stronger scientific basis for the proposal to require testing and sanitation of food contact surfaces for Listeria species.1 In general, the scientific literature indicated that the relationship between the prevalence and level of Listeria species in the plant environment (e.g., food contact and non-food contact surfaces) to the prevalence and level of Listeria monocytogenes (L. monocytogenes) in ready-to-eat (RTE) meat and poultry products is not well understood. To better understand this relationship, FSIS requested public input as part of the proposed rule for RTE meat and poultry products (66 FR 12609). In addition to the public request for data, FSIS initiated the planning and development of this risk assessment to: 1) provide insight into the relationship between Listeria species on food contact surface(s) and L. monocytogenes in RTE meat and poultry products; and 2) to evaluate the effectiveness of food contact surface testing and sanitation regimes, pre- and post-packaging interventions, use of growth inhibitors, and combinations of these interventions to mitigate contamination on RTE meat and poultry products and reduce the subsequent risk of illness or death from L. monocytogenes.
