STOUGHTON, Wis. (WFRV) – The Centers for Disease Control and Prevention (CDC) issued a report approximately nine months after an incident at a Wisconsin pizza restaurant where THC-infused oil was utilized in preparing dough.

The report states that at least 85 people, aged 1 to 91, consumed food at the pizza restaurant in Stoughton, Wisconsin, between October 22 and 24, 2024. According to the CDC, the restaurant was located in a building with a shared kitchen, used by a state-licensed edible THC vendor.

Initial reports emerged as emergency medical services informed Public Health Madison and Dane County (PHMDC) that seven individuals had been transported to local hospitals with symptoms such as dizziness, sleepiness, and anxiety. All reported eating at the same local restaurant.

The seven individuals were treated at a Stoughton hospital with THC intoxication symptoms. One person who had eaten pizza from the same place reported that they had a positive THC test result without knowingly consuming any, prompting an outbreak investigation.

The restaurant closed immediately on October 24, confirming to PHMDC about the THC vendor in the shared kitchen. According to the CDC report, the restaurant owner confirmed that they ran out of cooking oil on October 22, using some from the shared kitchen to prepare dough.

Further investigation revealed that the oil used tested positive for THC, as the restaurant mistakenly used THC-infused oil from the cooperative kitchen to prepare dough. No criminal charges were filed as police deemed the contamination to be unintentional.

The restaurant reopened on October 26 after deep cleaning and sanitation procedures approved by the Wisconsin Food Code.

The CDC report stated the following:

“85 persons who responded to a health department questionnaire reported symptoms consistent with THC intoxication that occurred within 5 hours after eating food from a pizza restaurant.”
