A Wisconsin restaurant, Famous Yeti's Pizza in Stoughton, unintentionally served pizzas laced with tetrahydrocannabinol (THC), the psychoactive compound in marijuana, affecting nearly 100 customers in late October 2024. According to a CDC report, the incident occurred when the restaurant ran out of cooking oil and used THC-infused oil from a shared kitchen in the same building.
Between October 22 and October 24, at least 85 people, aged 1 to 91, experienced symptoms of THC intoxication, such as dizziness, sleepiness, and anxiety, after eating at the restaurant. Seven people were hospitalized, but all have since recovered. The restaurant's owner, Cale Ryan, expressed regret and took full responsibility for the oversight, stating, "We acted with carelessness in prepping dough and ended up tainting our product."
Health officials, including Public Health Madison & Dane County, investigated the incident and determined it was an accident. The Gizmodo report noted that no criminal charges were filed. The restaurant reopened on October 26 after thorough cleaning.
The CDC report highlighted the need for clearer labeling and secure storage of THC-containing ingredients to prevent similar incidents. As THC-infused products become more common, public health officials urge vigilance to avoid unintentional exposure.
