Omg so honestly story time. I got diagnosed with ocd BECAUSE of botulism. I was convinced that not only did I have it that but I gave it to my elderly neighbour. I wasn't afraid of getting it myself (though like you said I am afraid of neurological effects.) But I was convinced I gave my elderly neighbour botulism.
You see, I homebrewed a batch of alcohol in my room with sugar and turbo yeast. I made a few different kinds. However gas from carbonation can build up if you don't have it properly penetrated to let air out and in. It even comes down to PH level and I was freaking out so bad because basically I did literally everything possible to make botulism and I'm to this day not convinced I didn't as the bottle had inflated, which I thought was just gas buildup and normal.
So here I was for 2 weeks knocking on my neighbour's door every morning, couldn't sleep, calling poison control, going to the doctor. Finally they were like "here's some ativan" and my mom threw out my yeast so I couldn't make any more potential botulism. And poison control asked me to please stop calling.
Honestly it is one of my deepest regrets, I'm joking about it lightheartedly but I do take it very seriously. I should not have shared crudely made homemade alcohol with my neighbour, not to mention it was like 30%.
But yes, botulism is very very very very very very VERY scary and while I made a joke about it I take it seriously and wouldn't intentionally do that-- not to mention even the gasses are dangerous!
