Food Safety STL

Helping City of St. Louis residents report cases of foodborne illness to the Department of Health through social media

What is Food Safety STL?

Food Safety STL (@FoodSafetySTL) is a Twitter account set up for residents to report cases of suspected foodborne illness, and further interact with the Department of Health. Meanwhile, a corresponding internal social media application will capture tweets that mention or use keywords related to foodborne illness located within a 25-mile radius from the center of the City of St. Louis. These captured tweets will prompt a response from the Food Safety STL Twitter account to provide further information on reporting. After a report has been submitted, the individual will receive either a follow-up reply tweet and/or an email providing him/her with a case number.

Complaints that fall outside of this jurisdiction will be appropriately referred to the corresponding local health department and the state health department.

Foodborne Illness and Social Media

Foodborne illness, also known as food poisoning, occurs when you get sick after consuming contaminated foods or beverages.

The CDC reports as few as 2.9% of those who become sick with foodborne illness seek medical care and most do not report their illness. As a result, existing surveillance systems only capture a small fraction of the disease burden, making prevention and evaluation of existing food safety policies and programs challenging. New media and information channels, such as social media and search engines, are a promising source of data for improving disease surveillance and reporting.
