- "As of May 15, 2023, the investigation has identified 50 ill people who ate at the restaurant between March 28 and April 17, 2023, of whom 44 people reported eating morel mushrooms. There have been three hospitalizations and two deaths associated with this incident. A sample of leftover mushrooms were collected from the restaurant and laboratory analysis determined that the sampled mushrooms were true morels."
- "Currently, no pathogen, toxin, pesticide, or heavy metal has been identified; however, state and local partners have collected consumer samples from the restaurant and testing and analysis are ongoing. Although epidemiological evidence indicates that morel mushrooms consumed at the restaurant are likely the cause of illnesses, mushroom poisonings can be difficult to diagnose as the exact chemical nature of some toxins found in wild-type mushrooms are currently unknown."
- "Although the mushrooms sampled from the restaurant were found to be true morels, there are varieties of “false morels” that may be mistaken for a true morel due to a similar appearance. “False morels” are toxic and should not be consumed, cooked or uncooked. Gyromitrin is a toxin found in some varieties of false morel mushrooms and it has been linked to several cases of mushroom poisoning and can be fatal even in relatively small amounts. Gyromitrin poisoning can cause symptoms such as headache, vomiting, diarrhea, dizziness, loss of coordination, and in severe cases, seizure, heart failure, liver and kidney damage and death. Gyromitrin toxin can be partially broken down by high temperature; however, even with cooking, toxins may remain and can lead to illness or toxicity."
- "Wild-type mushroom poisonings can cause a variety of symptoms ranging from mild illness to death. Symptoms of wild-type mushroom poisoning depend on the specific toxin, the amount ingested, and the individual. The presence and levels of toxins in any individual species of mushrooms can change over time and by geographic location of where the mushroom was harvested."
