In Oelde, located in the Warendorf district, more than 70 people reported gastrointestinal symptoms, including vomiting and diarrhea, after visiting a local kebab snack bar. Initial reports of 15 cases rose sharply, with three individuals requiring hospital treatment. Authorities ordered a cleaning and disinfection of the premises while awaiting laboratory results from food, environmental, and employee stool samples.

Health authorities later identified Norovirus as the likely cause of the infection cluster after finding the virus in several stool samples from those affected. Because testing of food items yielded unremarkable results, officials ruled out contaminated food as the source, suggesting instead that the infections spread through direct or indirect person-to-person contact. The snack bar was permitted to resume operations following thorough disinfection.
