“During October 22–24, 2024, at least 85 persons, ranging from age 1–91 years, ate food from a restaurant in Wisconsin and experienced symptoms consistent with THC intoxication. The restaurant was in a building with a cooperative (ie, shared) kitchen used by a state-licensed vendor who produced edible THC products. The restaurant mistakenly used THC-infused oil from the cooperative kitchen to prepare dough,” says a final report from a CDC investigation into an October 2024 incident at a Madison, Wisconsin-area pizza place called “Famous Yeti’s.”
“Tetrahydrocannabinol (THC), a psychoactive substance found in Cannabis sativa plants, including varieties such as hemp, is increasingly being used in consumer products. On October 24, 2024, local emergency medical services reported to Public Health Madison & Dane County in Wisconsin that since October 22, they had transported seven persons to a local hospital for various symptoms, including dizziness, sleepiness, and anxiety. All seven persons reported having recently eaten food from the same local restaurant. Investigation by PHMDC determined that on October 22, the restaurant had run out of cooking oil and used oil from a cooperative kitchen located in the same building. One of the vendors who used the kitchen made edible products using hemp-derived Δ9-THC.”
