Success Stories
These stories illustrate the work FoodCORE does to advance public health across the United States.
FoodCORE experts work to detect and respond to outbreaks, train professionals and strengthen health systems, and create programs that increase the safety of people’s food, water, and environment. Read about some of the specific ways we do this below.
Colorado Stops a Multistate Salmonella Outbreak Linked to Seafood
During foodborne disease outbreaks, investigation and response partners must work collaboratively to stop the current outbreak, determine how contamination occurred, and implement measures to prevent future outbreaks. When an outbreak is particularly challenging, such as a multistate outbreak with exposures occurring in a single state, it is crucial that all partners work together closely and maintain clear, bi-directional communication to respond effectively and efficiently.
Past Success Stories
FoodCORE and OutbreakNet Enhanced: Leveraging Enhanced Capacity During the COVID-19 Pandemic
During the COVID-19 pandemic, public health staff were pulled from their regular job duties to support the unprecedented pandemic response. Like other health departments, Foodborne Diseases Centers for Outbreak Response Enhancement (FoodCORE) and OutbreakNet Enhanced (OBNE) sites were faced with the challenge of conducting routine enteric disease surveillance and outbreak response activities with fewer epidemiology, laboratory, and environmental health staff. FoodCORE and OBNE sites found innovative ways to maintain routine work during the pandemic by leveraging their enhanced capacity and adapting their workflows.
Connecticut Leads Coordinated Investigation and Response to Contaminated Cheese
When people get sick from the food they eat, public health officials must work together to figure out the food that caused the illness. On February 12, 2021, the Centers for Disease Control and Prevention (CDC) announced that seven people from four states were infected in an outbreak of Listeria monocytogenes, including one ill person in Connecticut. Leading up to the Food Safety Alert posted by CDC, the Connecticut Department of Public Health (CT DPH), along with CDC, U.S. Food and Drug Administration (FDA), and public health and regulatory officials in the other states with ill persons, were working quickly to investigate the multistate outbreak.
Using Foodborne Illness Complaint Systems as an Effective Tool for Surveillance
Foodborne illness complaint systems are an effective surveillance tool for detecting enteric illnesses. Collecting complaints of suspected foodborne illness allows public health agencies to detect potential outbreaks sooner and implement control and education measures to prevent more people from getting sick. Many public health agencies across the United States have implemented complaint systems in their own jurisdictions, including three FoodCORE centers: Minnesota, Utah, and Tennessee.
Extending Capacity Beyond Food
Since 2010, FoodCORE centers have used targeted resources to improve capacity for foodborne disease surveillance, detection, and response activities at the state and local level. While their efforts primarily focus on foodborne outbreaks caused by Salmonella, Shiga-toxin producing Escherichia coli, and Listeria, the centers’ improved capacity has successfully aided in the response to enteric disease outbreaks from other sources, such as waterborne and zoonotic outbreaks, and outbreaks from other enteric pathogens.
FoodCORE Centers Investigate Zoonotic Outbreaks
Diseases that are shared between animals and people are known as zoonotic diseases. It is hard to know which animals could be carrying zoonotic diseases, especially since animals carrying germs often look and act healthy and normal. FoodCORE centers work to quickly detect, investigate, respond to, and control zoonotic outbreaks, just as they do with other enteric disease outbreaks. Investigating zoonotic outbreaks can be challenging, and the link to animal exposure may not be easy to identify.
FoodCORE Centers and Real-World Use of GI CIDTs: Adapting to Changes in Clinical Diagnostics
The consequences of increased use of culture-independent diagnostic tests (CIDTs) on disease surveillance are no longer theoretical, and FoodCORE centers are making changes to assure they can continue to efficiently identify and investigate enteric outbreaks. They will continue to share lessons learned with other state and local health departments as they work with real-world implications of CIDTs.
Innovative Product Testing Method Solves Outbreak Linked to Raw Milk
It is difficult to detect Campylobacter in raw milk, so Utah health agencies collaborated with partners to use a new sampling method to test raw milk for the outbreak strain. Their determination to confirm the source of the outbreak and success of this sampling methods stopped the outbreak and prevented additional illnesses.
Going the Distance: Tennessee and Colorado Successfully Collaborate Despite being Miles Apart
Though they are many miles apart, the Tennessee and Colorado FoodCORE centers were able to bring together epidemiology, laboratory, and environmental health professionals to conduct a complete investigation of a Salmonella outbreak at a summer camp. By working together, investigators in multiple states can identify and thoroughly investigate more outbreaks.
Tennessee FoodCORE Team Aims to Keep Splash Pads Safe and Fun
After linking a Salmonella outbreak to a splash pad in west Tennessee, the Tennessee FoodCORE team investigated splash pads across the state to identify their hazards and to prevent similar outbreaks. This investigation led the Tennessee Department of Health to develop guidance to help keep splash pads safer for people to enjoy.
Using Online Restaurant Reviews to Find Local Foodborne Outbreaks
Local health departments detect many foodborne outbreaks through illness complaint systems. Each year, the New York City Department of Health and Mental Hygiene’s illness complaint system receives approximately 3,000 complaints, but it is likely that many more are never reported. Staff at DOHMH collaborated with Columbia University and Yelp, an online review site, to pilot a project to identify foodborne outbreaks that may go undetected through traditional complaint systems.
Asking the Right Questions Quickly from the Beginning
During an already busy summer in 2014, several FoodCORE centers proved once again to be instrumental during the investigation of a multistate outbreak of Salmonella infections – this time involving multiple Salmonella serotypes. PulseNet initially detected several ill people with a rare DNA fingerprint of Salmonella Newport and multiple health departments, including six FoodCORE centers, immediately began working with their federal partners on the investigation.
Stopping a Salmonella Outbreak among Infants in a Nursery
In a quaint town along the South Carolina coast, an otherwise healthy 5 month old girl began to show signs of getting sick. After a few days of diarrhea, her condition worsened, and she started having blood in her stools. Her parents immediately took her to their pediatrician, where a stool sample revealed a Salmonella infection.
Wisconsin’s Public Health Sleuths Take to the Lake
In the summer of 2012, a Wisconsin lake was the site of an outbreak of gastrointestinal illnesses. Local public health officials at the Jackson County Health Department were quickly notified of these illnesses and started to investigate the situation. Early on, officials found that many of the sick people had been at the same outdoor recreation area the day before they got ill.
FoodCORE and FoodNet: Complementary Collaborations in Connecticut
In 2012, CDC scientists monitored between 16 and 57 potential food poisoning clusters each week and investigated more than 200 multistate clusters nationwide. Two of CDC’s food safety programs partner with 15 jurisdictions to get ahead of stubborn foodborne outbreaks: FoodCORE and FoodNet.
Tennessee Detectives Investigate an Outbreak of Cryptosporidium
In the summer of 2012, public health officials in Tennessee were notified that a group of volunteers were sick with gastroenteritis. The volunteers were from multiple states and had traveled to Tennessee to work on a farm. Tennessee officials collaborated with several other states to figure out what caused the illness.
“U” niversity partnerships-at the core of FoodCORE
It’s hard to imagine that simply having students talk with patients about chicken livers, raw milk, and sprouts could help protect our food supply and save lives, but it’s true. These students have become integral in identifying the culprits in outbreaks of foodborne illness across the country.
