I guess anywhere where HAB occurs, take a look at the map here

You can find distribution maps for different cases of poisoning as well.
Now my turn for a ridiculous question:
You are not planning to make dinner for anyone with it, are you? :P
According to the map you provided, I appreciated the remoteness of the points from me. I decided that I would use mushrooms in case of urgent need. Mushrooms for me - a more affordable option. In my environment there are several specimens that have long been forcing me to prepare a similar dinner)))
In that case I guess you should stick with the resources available in your place ;)
👍
waiting for new interesting inspirational stories!
