It is difficult to determine what specific exposure caused a person with a sporadic infection to become ill; however, risk factors can be explored through population-based studies. Studies are conducted to examine the importance of various possible risky exposures such as specific foods and practices such as food preparation and handling practices as contributors to illness caused by specific pathogens. Cases of infections with the pathogens under study are ascertained through routine FoodNet surveillance. FoodNet staff contact case-patients and healthy controls if a case-control study is being performed to administer a questionnaire. Studies may also include molecular subtyping or antimicrobial resistance testing of patient isolates.

Foodborne illness - Wikipedia
Foodborne illness is a major cause of disease in the United States. Each year, 31 known foodborne pathogens bacteria, viruses, and parasites cause an estimated 9 million illnesses and unspecified agents account for an additional estimated 37 million illnesses, for a total of 48 million illnesses. To find out which foods make people in the United States ill, CDC developed estimates of the food sources of foodborne illnesses caused by known pathogens. But such links are possible during outbreaks because many people get sick from the same food. By using data from nearly 4, outbreaks, CDC estimated the number of illnesses due to each of 17 food categories. Figure A. This was the first time CDC attempted such a comprehensive set of estimates for foodborne illness.
Foodborne Illness Outbreak Investigation
Infection with other pathogens and hemolytic uremic syndrome HUS may also be reportable. Authority for disease reporting rests at the state level, and states voluntarily report nationally notifiable conditions to CDC. Frequently, diagnoses remain unconfirmed until laboratory tests are completed. Outbreaks of suspected foodborne illness and infections commonly transmitted through food should be reported.
Although many public health articles have been published detailing foodborne illness outbreaks, a medical literature search revealed no articles that detail a case study or a specific response of a deployed U. This article describes a recent public health case study of a U. It highlights public health factors which may affect U. Methods: Eight food samples and five water samples were collected.
