Food Poisoning

Foodborne illness, often called food poisoning or foodborne disease, is any illness that results from eating contaminated food. It is a common cause of diarrheal illness in Wisconsin.

If you believe you or someone you know became ill from eating a certain food, report your illness with the online reporting tool. Learn more about the tool by viewing the Food Poisoning: Report an Illness Caused by Food or Water webpage.

If you are severely ill, see a doctor immediately. Food poisoning can be especially dangerous for infants, pregnant people, older adults, and people who are immunocompromised.

Reporting illnesses helps public health officials identify potential foodborne disease outbreaks. By investigating foodborne disease outbreaks, possible problems in food production, distribution, and preparation that may cause illness can be discovered and steps can be taken to prevent others from getting sick.
