A food poisoning outbreak that killed two people and sickened 51 has highlighted just how little is known about morel mushrooms and the risks in preparing the popular and expensive delicacy.

The FDA conducted an investigation into morel mushrooms after the severe illness outbreak linked to Dave’s Sushi in Bozeman, Montana, in late March and April. The investigation found that undercooked or raw morels were the likely culprit, and it led the agency to issue its first guidelines on preparing morels.

“The toxins in morel mushrooms that may cause illness are not fully understood; however, using proper preparation procedures, such as cooking, can help to reduce toxin levels,” according to the FDA guidance.

Even then, a risk remains, according to the FDA: “Properly preparing and cooking morel mushrooms can reduce risk of illness, however there is no guarantee of safety even if cooking steps are taken prior to consumption.”

    i know this isn’t always a necessity with mushrooms but I’m finding it funny that the FDA was forced to say “ay, cook your food”

      People think of mushrooms like vegetables and most wouldn’t suspect that it’s often more important for mushrooms to be fully cooked than it is for meat.

      People eat rare burgers all the time and only rarely get sick, morels are actually poisonous when undercooked so you’re guaranteed to get sick if you eat enough of them.

          i wouldn’t say they’re inedible, just so utterly unappealing that you can’t get yourself to eat them.

          i can’t imagine a raw potato is much different to digest than a raw carrot

            Except, that they contain compounds like lectin and solanin, that can cause gastric distress…

            My brother in law used to eat baby potatoes raw as a snack. Pack them in his lunch for work. Never bothered him but he is an interesting dude. With a stomach of steel apparently.

        I’ve had plenty of raw mushrooms in my life. Just button and baby bella though. Never thought twice about it and haven’t had any problems either.

          Those are both the same mushroom, Agaricus Bisporus which is mildly toxic and carcinogenic when eaten raw. You probably won’t get an upset stomach unless you eat a lot of them but it’s really not worth the risk just to ruin a perfectly good salad with nasty raw mushrooms.

        I mean if they specialize in it, they should know which things are safe to eat uncooked

          It’s a sushi place 500 miles from the closest salt water. It’s like gator meat in Buffalo NY - untrustworthy.

            Eh, I’m pretty sure every piece of raw sushi has to be frozen before consumption anyway. So being further from the ocean doesn’t really matter

    Anybody who knows mushrooms knows that the vast majority of them have to be well cooked or, at the least, they are likely to cause stomach upset.

    At Dave’s, a marinade, sometimes boiling, was poured over the raw mushrooms before they were served, Parker said.

    This is the restaurant’s fault.

      even completely nontoxic mushrooms can upset your stomach if you eat a bunch of them, and especially if you’re not used to doing so.

      they’re not trivial to digest

        Mushroom cells contain a ton of chitin, which is what crustacean shells are mostly made of. I happen to have a stomach of steel, so it doesn’t bother me that much. Or maybe, I am just really used to it.

        If you have a sensitive stomach, it’s much easier to take shrooms as a tea or steeped in some lemon juice for an hour. The heat or the acid works wonders on chitin… (It’s also rumored that citric acid will work wonders on psilocybin and convert some of it to back to psilocin as well. That isn’t for a beginner, btw.)

        Yep. And there are some people who can’t even tolerate your basic white mushroom even in pretty small amounts. Mushrooms aren’t that easy on the stomach.

      My FIL served slightly grilled mushrooms. I forget the name but it’s not toxic, but they were undercooked and I was incredibly intoxicated and ate a bunch. Served with a delicious sauce, went together nicely.

      The next day, well I hadn’t puked that much ever before. 12 hours straight intense puking and another 12 hours laying on the sofa

      Yes! You should never consume raw mushrooms, some people can even have reactions to white buttons and shiitake if not cooked

        Not tooo hard a fry.

        Morels like a little butter and oil fry with a flour batter and a generous salting for me. They are plentiful near my parents house, though I think I actually prefer hen of the woods in the fall.

    Dave’s Sushi is a known food poisoning spot, haha. This is not the first time they have run into issues. I remember in university, classmates would go there on a date, fall asleep together, and would say they’d both be up all night vomiting. But they said the sex (prior to getting hideously sick) was great. Young people, haha. Didn’t really bat an eye back then, it was just a known quantity. My general rule of thumb is to not get sushi or other raw seafood in Montana or any other landlocked state.
