Foodborne Illness

The Centers for Disease Control and Prevention estimates that 1 in 6 Americans (about 48 million people) gets sick from food-related illnesses each year, and that more than 125,000 of those people require hospitalization. Foodborne illness is caused by ingesting or preparing foods and beverages contaminated with disease-causing pathogens. More than 250 different foodborne diseases have been discovered and are caused by a variety of bacteria, viruses, parasites, toxins or chemicals.
Reporting a Foodborne Illness

If you believe that you've become sick while dining in a St. Charles County restaurant or from food products obtained from a St. Charles County food vendor, please call the Division of Environmental Health and Protection at 636-949-1800 or register your complaint online.

Tracking Illness & Preventing the Spread

Staff from St. Charles County's Division of Environmental Health and Protection and Division of Health Services work together with organizations throughout our community to prevent foodborne outbreaks before they occur and to track the sources if cases are discovered. The St. Charles County Food Code outlines food safety procedures that restaurants, grocery stores, temporary food vendors and other entities must follow when providing food services to the public. In addition, health department staff investigates incidents of food contamination to prevent outbreaks. The goals of these investigations are to discover the probable cause of the illness, to minimize further spread of illness from this incident and to provide controls that will prevent recurrence.

Preventing Foodborne Illness

The most important thing you can do to prevent the spread of foodborne illness is to wash your hands and preparation utensils regularly in hot, soapy water. In addition, following the 4 keys to food safety (Clean, Separate, Cook, and Chill) will help to prevent contamination. As temperature changes can influence the development of some disease-causing agents, it's very important to keep cold foods cold and hot foods hot before, during and after preparation.

The Most Common Foodborne Diseases 

Raw and undercooked foods, as well as products that have been prepared or stored improperly, are items that are most likely to become contaminated with potentially harmful microbes. Although illnesses can affect different people in different ways, common symptoms of foodborne illnesses are fever, nausea, diarrhea and abdominal cramping. Most food-related illnesses cause a short-lived discomfort, but some can become life-threatening.
