Surveillance Reports

FoodNet

The Foodborne Diseases Active Surveillance Network, referred to as FoodNet, is the principal foodborne disease component of CDC's Emerging Infections Program and provides the data necessary for measuring the progress in foodborne disease prevention.

Foodborne Disease Outbreak Surveillance

The Foodborne Disease Outbreak Surveillance System reports foodborne disease outbreaks and illnesses by etiology and food commodities in the United States from all states. CDC collects reports of foodborne outbreaks due to enteric bacterial, viral, parasitic, and chemical agents. State, local, and territorial public health agencies report these outbreaks to the Foodborne Disease Outbreak Surveillance System through the National Outbreak Reporting System (NORS).

NOTE: Data on foodborne outbreaks:
Foodborne Outbreak Online Database (FOOD) is an annual listing of foodborne disease outbreaks in the United States (1998–2009) which has been designed to allow the public direct access to information on foodborne outbreaks reported to CDC. Most outbreaks are reported to the system by the state, local, territorial, or tribal health department that conducted the outbreak investigation. Outbreak reporting is voluntary. Multistate outbreaks are generally reported by CDC. For more information, see FOOD Tool Questions and Answers.

NARMS

The National Antimicrobial Resistance Monitoring System, referred to as NARMS conducts surveillance for antimicrobial resistance among foodborne bacteria in humans, retail meat, and animals.

National Surveillance Reports

CDC collects data from all states on infections due to enteric bacterial pathogens including Listeria spp, Salmonella spp (including Salmonella serotypes Typhi and Paratyphi A, Partyphi B, and Paratyphi C), Shiga toxin-producing Escherichia coli (STEC), Shigella spp, and Vibrio spp (including V. cholerae), which are nationally notifiable. CDC also collects data from all states on cases of botulism, which is caused by toxins produced by Clostridium botulinum; botulism is also nationally notifiable. Information is gathered from both "laboratory-based" and "case-based" surveillance systems.

National Laboratory-based Surveillance

"Laboratory-based" surveillance relies on the collection of information about bacteria that have been identified by laboratory testing of ill persons. Bacteria are isolated and identified from patient specimens by clinical laboratories, and the isolates are then submitted to state public health laboratories for further characterization or reported to them. CDC conducts laboratory-based surveillance for infections caused by Salmonella, Shigella, and Shiga toxin-producing Escherichia coli (STEC) using reports from state and territorial public health laboratories.

National Case-based Surveillance

"Case-based" surveillance relies on the collection of reports of cases of illness. These case reports include information such as the symptoms of illness, when those symptoms started, demographic information about the ill person (age, sex, state of residence), and key risk factor information (e.g., travel, activities, foods consumed) for the specific infection. CDC conducts case-based surveillance for botulism, cholera and other Vibrio illnesses (including V. parahaemolyticus and V. vulnificus infections), Listeria infections, and Typhoid and Paratyphoid Fever infections by collecting case report forms for each person who is diagnosed with a case of one of these illnesses. These data are reported to CDC by state and territorial public health departments.
