Undercooked Morels Associated With Deadly Outbreak in MT

The Centers for Disease Control and Prevention (CDC) is reporting that uncooked and undercooked morels were associated with a deadly outbreak at Dave's Sushi in Bozeman Montana in March and April 2023 that killed two people. Fifty-one people were sickened after eating at that restaurant. Three people were hospitalized. The issue is that while morel mushrooms are considered edible, little is known about the human health effects of the fungi. In the study, the consumption of raw morels was more strongly associated with illness than the consumption of cooked or partially cooked morels. After the outbreak the CDC issued an advisory about eating morel mushrooms, whether cooked or not, saying that wild mushrooms should be consumed at your own risk. Morels were the common food consumed … [Read more...]

FDA CORE Table Updated With Info About Cyclospora Outbreak

The FDA CORE Table has been updated with new information about one of the Cyclospora outbreaks and about the Salmonella Paratyphi outbreak. There are currently five outbreak investigations that are active on the table. The cyclospora outbreak that has sickened at least 20 people is over and the investigation into the outbreak has ended. Based on epidemiological investigations conducted by the Centers for Diseases Control and Prevention and state and local partners, the government has determined that imported broccoli was contaminated with the parasite. All samples that were analyzed were negative for cyclospora, so investigators were not able to confirm a specific type or producer of broccoli as the source of the outbreak. For the other outbreak of cyclospora, the case count has … [Read more...]

FDA Releases Morel Advisory After Dave’s Sushi Illnesses

The FDA releases Morel advisory after illnesses among patrons of Dave's Sushi in Bozeman, Montana. At least 50 people were sickened, and two customers died after eating at that establishment, although the manner of death has not been established. Morel mushrooms are most often foraged from the wild. While morel mushrooms are generally regarded as safe to eat, they may contain toxins that can cause health problems. The advisory states that the toxins that can cause illness are not fully understood. Cooking the mushrooms properly can reduce toxin levels, but the FDA says that people should eat morel and other wild-type mushrooms at their own risk. As of May 19, 2023, the outbreak at Dave's Sushi has sickened 50 people who ate at the restaurant between March 28 and April 27, 2023. … [Read more...]

Dave’s Sushi Outbreak Remains Unsolved; Restaurant Reopens

Two people have died after eating at the restaurant, although those deaths are being investigated and the manner and causes of the deaths are pending until autopsy results are available. Food samples, including salmon and morel mushrooms, which were suspected in this outbreak, have been collected and analyzed. All samples have come back negative for a series of pathogens and toxins. The Gallatin … [Read more...]

Import Alert For Morel Mushrooms Imported by a Company in France

The FDA issued Import Alert 25-02 for morel mushrooms imported from a company in France on May 23, 2022 because, in the past, shipments of canned and dried mushrooms were detained because of the presence of Gyromitra esculenta, or false morel. This species can produce monomethylhydrazine (MMH), which is a toxin that can cause severe gastrointestinal illnesses and, in some cases, death. The Center for Food Safety and Applied Nutrition (CFSAN) identified another species, Verpa bohemica, or early morel, which can also cause illness in some people. All morel mushrooms imported from that company and false morel mushrooms, also imported from that company, in the form of fresh, canned, and dried, are subject to this import alert until further notice. Morel mushrooms are a distinctive … [Read more...]
