Core FoodNet Activities

Attributions Working Group

Elaine Scallan, Paul Cieslak

Liane Ong

1st Thursday of the month;
11:00-12:00 pm EST

Knowing what foods cause the most human illness is essential when developing and prioritizing food safety interventions. The FoodNet Attribution Working Group focuses on how FoodNet data can be used to attribute the burden of foodborne illness to specific foods and settings. A major project currently underway is a molecular approach to estimating the proportion of laboratory-confirmed cases of human infections from Salmonella in meat, poultry, and eggs in the United States.

Burden Working Group

Tim Jones, Elaine Scallan

Nadine Oosmanally

Quarterly; 4:00-5:00 pm EST

Several “surveillance steps” are necessary for a case to be ascertained by laboratory-based surveillance: the ill person must seek medical care, a stool specimen must be submitted, and the laboratory must test for the pathogen and report the case to public health. The Burden Working Group uses data from the FoodNet Population Survey and other sources to better understand these surveillance steps, thereby allowing for a better estimate of the overall burden of disease in the community.

The FoodNet Population Survey Working Group is responsible for the design, implementation and analysis of the FoodNet Population Survey. The FoodNet Population Survey is conducted on a periodic basic and collects key information on prevalence and incidence of diarrheal illness in the community. It also provides a snapshot of food consumption patterns, food safety behaviors and population demographics. 

Trends Working Group

Olga Henao

Olga Henao

Quarterly

The FoodNet Trends Working Group meets on a quarterly basis to evaluate and develop the methods used in FoodNet to examine trends in the incidence of specific foodborne pathogens over time. The working group is also trying to improve how FoodNet monitors trends in the incidence of hemolytic uremic syndrome (HUS) and outbreaks occurring in FoodNet sites.

Interventions Working Group

Heather Bair-Brake, Mary Patrick

Heather Bair-Brake

4th Tuesday of the month;
2:00-3:00 pm EST

The goal of the Intervention Working Group is to disseminate research findings gained through FoodNet active surveillance and special studies. The group prepares short summaries of recent FoodNet publications for dissemination through the FoodNet website, newsletter, partner organizations and presentations at scientific conferences. Recent projects include development of a FoodNet brochure, lessons learned document and a fact sheet on reptile-associated illness. In 2006, the group completed a study to assess safe food practices, knowledge, and policies in long-term care facilities.

Other Working Groups

HUS/O157 Working Group/O157 Cohort Study Working Group

Ruthanne Marcus, Linda Demma

Liane Ong

2nd Thursday of the month;
12:00-1:00 pm EST

The FoodNet STEC/HUS Working Group focuses on surveillance for Shiga toxin-producing Escherichia coli (STEC) infections and hemolytic uremic syndrome (HUS) related epidemiological studies in FoodNet sites. Recent working group efforts have sought to improve the monitoring of STEC O157 and STEC non-O157 infections in light of changes in laboratory diagnostic practices. The working group are also overseeing the largest ever study of the predictors for developing HUS following STEC O157 infection, looking specifically at antimicrobial treatments, clinical signs, and host genomics.

Outbreak/Norovirus Working Group

Chris Braden, Tim Jones

Ida Rosenblum

3rd Thursday of the month;
3:00-4:00 pm EST

Outbreaks are an important element in determining the burden of foodborne illness, and in attributing specific illness to specific food products. The FoodNet Outbreak Working Group collects supplemental information on outbreaks occurring in the FoodNet sites and conducts epidemiological studies on outbreaks. Current projects include a study looking at the incubation period for Salmonella and a study to better understanding the role of restaurants in outbreak modification.

Antibiotic Resistance Working Group

Tom Chiller

Sri Wilmore

4th Thursday of the month;
1:00-2:00 pm EST

The FoodNet Antibiotic Resistance Working Group focuses on monitoring emerging resistance trends in the FoodNet sites. Recent working group efforts have led to site-based resistance testing studies and an improved Campylobacter sampling scheme for NARMS. In 2006, the working group launched a two-year study to determine and compare the severity of clinical outcomes among infections with pansusceptible and multi-drug resistant non-Typhi Salmonella strains.

Campylobacter Working Group

Linda Demma

Liane Ong

As needed

The FoodNet Campylobacter Working Group focuses on the epidemiology of Campylobacter infections in FoodNet sites. The working group has recently undertaken several studies to investigate the possible causes of marked regional variation in the incidence of Campylobacter. One study was launched to determine if Campylobacter incidence is correlated with prevalence and quantity of Campylobacter present in U.S. retail poultry, another, looked at the link between incidence and clinical diagnostic laboratories practices.

The FoodNet C. difficile Working Group focuses on an emerging infection — community-associated Clostridium difficile. The working group implemented enhanced surveillance for community-associated C. difficile infection in FoodNet sites over a three-month period. The working group is now designing a prospective study to identify behavioral, dietary, and medical risk factors for community-acquired C. difficile infection.
