VII. INTERPRETATION AND CONCLUSIONS
This risk assessment included analysis of the available scientific information and data in
the development of exposure assessment and dose-response models to predict the relative
public health impact of foodborne L. monocytogenes from 20 food categories. The
assessment focuses on predicting parative risk among ready-to-eat foods that
have a history of either L. monocytogenes contamination or were implicated
epidemiologically. The risk assessment focuses on the predicted relative risk associated
with these foods in relation to the overall incidence of listeriosis including both
apparently sporadic illnesses and illnesses associated with outbreaks. Illnesses attributed
to documented outbreaks are a small proportion of the total estimated annual cases of
listeriosis. Outbreaks frequently represent a breakdown in the food safety controls that
have been established to prevent such occurrences. For example, outbreaks of listeriosis
have been linked to failure to protect a frankfurter processing line from environmental
contamination caused by plant renovations (1998-99), use of defective processing
equipment in the production of chocolate milk (1994), and inadequate pasteurization of
milk used to make fresh soft Mexican-style cheese (1987). Therefore, maintenance of
food safety control systems an
