Food Safety and Inspection Service, USDA.
Notice of request for comment.
The Food Safety and Inspection Service (FSIS) is requesting public comment on a draft quantitative food safety risk assessment for Listeria monocytogenes (L. monocytogenes) that compares the risk of listeriosis from consumption of prepackaged ready-to-eat (RTE) deli meat versus RTE deli meat that is sliced and packaged at retail. The risk assessment analyzes the comparative risk of listeriosis from prepackaged RTE deli meat versus RTE deli meat that is sliced and packaged at retail using data from a study by the National Alliance for Food Safety and Security (NAFSS) and new consumer survey data from Research Triangle Institute (RTI) International, Tennessee State University, and Kansas State University.

L. monocytogenes is estimated to cause approximately 2,500 illnesses, 2,300 hospitalizations, and 500 deaths each year in the United States (Mead et al., 1999). L. monocytogenes is ubiquitous in nature. It is commonly found in the intestines of animals and humans without causing illness. It can survive for long periods of time in soil, leaf litter, sewage, silage dust, vegetation, and water. The organism has been found in many domestic and wild animals, fish, birds, insects, and snails. L. monocytogenes has been isolated from a variety of products, including raw milk, cheese made from unpasteurized milk, soft cheese, meat and poultry and their products, cole slaw, and cabbage. L. monocytogenes is found in the food-processing environment and can form biofilms on solid surfaces in food processing plants. L. monocytogenes can also survive adverse conditions on apparently smooth surfaces (http://www.fsis.usda.gov/Frame/FrameRedirect.asp?main=http://www.fsis.usda.gov/oa/topics/lmguide.htm).
Consumption of food contaminated with L. monocytogenes can cause listeriosis, a disease that results in high fever, severe headache, neck stiffness, and nausea. Listeriosis can also cause miscarriages and stillbirths, as well as fatal infections in those with weakened immune systems, such as infants, the elderly, and persons with HIV infection or undergoing chemotherapy (http://www.fsis.usda.gov/News_&_Events/Recall_051_2008_Release/index.asp).
To better understand the sources of foodborne L. monocytogenes infection, the Food and Drug Administration (FDA) and FSIS developed a quantitative risk assessment that compared the risk of listeriosis among 23 categories of RTE foods. The results of the risk assessment, completed in 2003, indicated deli meats pose the greatest risk for listeriosis, accounting for approximately 1,600 illnesses per year (http://www.foodsafety.gov/~dms/lmr2-toc.html).
Because of these findings, FDA and FSIS conducted a preliminary analysis using the deli meat model component of the 2003 FDA and FSIS Listeria monocytogenes risk assessment. This analysis estimated the relative risk of illness from Listeria monocytogenes on deli meat sliced and packaged at Federally inspected processing establishments compared to deli meat sliced at retail facilities. The results of the preliminary analysis indicated that approximately 80% of listeriosis cases related to deli meats were associated with those sliced at retail. However, because these results were based on a retail survey not specifically designed to collect contamination data on deli meats (Gombas et al. 2003), FSIS sought to gather targeted contamination data for prepackaged and retail-sliced deli meats to further examine the relative risk of listeriosis.
In the risk assessment released today—the Comparative Risk Assessment for Listeria monocytogenes in Ready-To-Eat Meat and Poultry Deli Meats—FSIS reanalyzes the relative risk of illness from Listeria monocytogenes on deli meat sliced and packaged at Federally inspected processing establishments compared to deli meat sliced at retail facilities based on new data.
II. The Draft Risk Assessment
The Comparative Listeria Monocytogenes in Ready-to-Eat Meat and Poultry Deli Meats risk assessment has undergone an independent external peer review consistent with the requirements in the Office of Management and Budget's “Final Information Quality Bulletin for Peer Review” and review by various government agencies. This quantitative risk assessment provides a science-based, analytical approach to collate and incorporate available data into a mathematical model. It provides risk managers with a decision-support tool to understand and evaluate the relative risk of slicing and packaging deli meat in retail facilities versus slicing and packaging deli meat in federally inspected processing establishments.
The deli meat pathway model of the draft risk assessment consists of four distinct stages: (1) A retail stage that determines the level of L. monocytogenes in prepackaged deli meats and those deli meats sliced at retail; (2) a growth stage that uses an exponential growth rate function to model the growth of L. monocytogenes in deli meat between purchase at retail and consumption; (3) a consumption stage that uses information about deli meat serving sizes and the number of servings consumed to estimate consumer exposure to the pathogen of concern; and (4) a dose-response stage that predicts the probability of death from consuming L. monocytogenes.
To update the deli meat pathway model of the 2003 risk assessment discussed above, FSIS obtained retail contamination data from the NAFSS study (Draughon, 2006) and used it in conjunction with new consumer survey data obtained by RTI International, Tennessee State University, and Kansas State University (Cates et al., 2006).
The results from this comparative Lm risk assessment model indicate that approximately 83% of listeriosis cases and deaths attributed to deli meat consumption are from deli meat sliced and packaged at retail.
As part of an evaluation of the draft comparative L. monocytogenes risk assessment, FSIS seeks comments about:
(1) The assumptions made,
(2) The modeling techniques,
(3) The data used, and
(4) The clarity of the draft risk assessment document.
FSIS will review and evaluate all public comments on this draft comparative risk assessment and make modifications to the assessment based on comments, as appropriate. The draft risk assessment is available electronically on the FSIS Web site (http://www.fsis.usda.gov/Science/Risk_Assessments/index.asp#RTE).
