Food poisoning happens after eating or drinking contaminated foods or beverages. Contamination occurs at any time throughout the food preparation process, including growing, distribution processes, storage, cooking, and service. Often, foodborne illness is the result of cross-contamination, poor hygiene, or improper heating and cooling of prepared foods.

If you suspect food poisoning after consuming an item from a restaurant, grocery store, convenience store, market, or public gathering, call IDPH’s IowaSic hotline at 1-844-469-2742.
