WASHINGTON, May 10, 2013 - To help minimize the public health burden of listeriosis, USDA's Food Safety and Inspection Service (FSIS) and the U.S. Food and Drug Administration (FDA) have conducted a major study to better understand the risk of foodborne illness associated with eating certain foods prepared in retail delicatessens and developed recommendations for changes in current practices that may improve the safety of those products.
The study, a quantitative risk assessment, provides a scientific evaluation of the risk of listeriosis associated with consumption of meats, cheeses and other ready-to-eat foods prepared in retail delis. It also examines interventions that limit the survival, growth or transmission of Listeria monocytogenes (Lm), the bacteria that causes listeriosis.
Control of Lm has long been an objective of the public health community. The Centers for Disease Control and Prevention estimates that infections with Lm causes about 1,600 illnesses, 1,500 hospitalizations and 260 deaths in the United States each year. Listeriosis is rare, but its fatality rate is very high (i.e., about 16 percent, compared with 0.5 percent for either Salmonella or E. coli O157:H7). It primarily affects older adults, pregnant women, newborns and adults with weakened immune systems.
"The risk assessment will be a tremendous asset in our efforts to reduce the 1,600 illnesses and 260 deaths attributed to this pathogen annually," USDA Under Secretary for Food Safety Dr. Elisabeth Hagen said. "Essential information has been gained from these findings, including the fact that once Lm enters a retail environment, it has the potential to spread due to cross contamination. This assessment highlights the importance of our work to prevent Lm from entering the retail environment in the first place, and provides a significant tool towards this effort to protect consumers and prevent foodborne illness."
The U.S.-focused study is the first of its kind. It quantitatively links retail deli practices to predicted public health outcomes, which has never been done before. The study is based on observations of deli employees' work routines; concentrations of Lm on incoming products and in the deli environment; simulations of the bacteria's transmission, such as from slicer to food; and dose-response modeling. The study was designed to apply to a range of deli establishments, from small independent operations to the deli departments in large supermarkets.
The study also reinforces the importance of FDA's Food Code recommendations to operators of retail delis. State, local and tribal jurisdictions can do their part to reduce listeriosis by enforcing all relevant provisions of the Food Code as part of their own food safety requirements.
No single intervention will put an end to Lm in food sold at retail delis, the study found. Instead, there are many steps that retail deli operators and their suppliers can take to help reduce listeriosis. The study's key findings include:
FDA and FSIS have taken many steps to enhance retail food safety in an effort to reduce listeriosis and other foodborne illnesses. For instance, since its initial release in 1993, the FDA Food Code has been revised to target Lm prevention, including more stringent temperature controls for refrigerated foods and limits on how long such foods can be retained after opening or preparation.
In addition, FDA has created educational materials in recent years to support foodservice operators, including guidance on how to keep deli slicers properly cleaned and sanitized, a handbook on employee health and personal hygiene, food-safety posters in nine languages, and video testimonials designed as training aids. FSIS is planning to provide outreach materials to retailers where ready-to-eat meat and poultry products are sliced, prepared, or packaged for consumption in the home. These materials will highlight risky practices based on the results of the interagency risk assessment and help retail establishments to adopt best practices that could decrease the potential for Lm growth or cross contamination.
Consumers, too, have a role to play in reducing listeriosis. For advice on keeping refrigerated foods cold, cleaning one's refrigerator regularly, and cleaning hands and kitchen surfaces often, visit foodsafety.gov. To further minimize any risk of listeriosis, FDA and FSIS recommend that older adults, pregnant women and adults with weakened immune systems reheat hot dogs and lunch meats until steaming hot.
The study was published today and can be read in its entirety on either the FDA or FSIS web sites. A public meeting to discuss the study and its findings will be held at USDA's Jefferson Auditorium at 1400 Independence Avenue, Southwest, Washington, D.C., on May 22nd, from 8:15 a.m. to 4:15 p.m. People who plan to attend the meeting are asked to register in advance at FSIS' website.
The risk assessment is in addition to other significant public health measures FSIS has put in place during President Barack Obama's Administration to date to safeguard the food supply, prevent foodborne illness, and improve consumers' knowledge about the food they eat. These initiatives support the three core principles developed by the President's Food Safety Working Group: prioritizing prevention; strengthening surveillance and enforcement; and improving response and recovery.
