Botulism normally kills so I don’t know anyone who has had botulism, and also it is very rare.
To prevent it you can correctly using the directions precisely, keeping everything clean and sterile. You wash the food like crazy using a brush, especially root crops because it is in the soil.
If you have any doubt about something you boil it for 20 minutes before you eat it.
Acidic foods don’t grow botulism and that is why you can can them with just a water bath method.
If you’re afraid, you could add a good dose of vinegar to everything, it would taste awful but it wouldn’t kill you.
People canned for years and botulism deaths were still pretty rare.
Won't work. Not for botulism, which isn't (usually) an infection.
It's caused by Clostridium botulinum. This organism forms spores, which makes it highly resistant to heat, so can survive the canning process if not done right for the particular type of food. Then it grows inside the can and produces a toxin. You get sick, usually, from poisoning by the toxin, not by the bacteria growing inside you (infection).
You can boil (or even pressure cook) food containing botulin toxin all you want, and it won't accomplish anything. Eat it and you're pretty much dead.
It's been estimated 1 gallon of botulin toxin would be enough to kill all humans on the planet.
The hard part, of course, is getting people to line up for their dose.
Botulin toxin is what they use for the botox treatment. Pelosi' best friend!
