Nothing will kill you if you boil it in water for 1 hour.
It’s good to know that would survive being boiled in water, as long as I am in there for less than an hour.
Actually.... that's not quite true. Lots of things produce toxins that aren't removed by boiling.... such as botulism. It grows when non acid things aren't canned properly, or when you put things like garlic in oil and don't refrigerate it.
That said, preserving is done a number of ways, not all of which are by refrigeration. Sugar, salt, acid and dehydration are also preservatives. That's why jams and pickles and beef jerky don't need to be in the fridge. They will keep.... but will eventually grow mold. Salt and drying are ways to preserve meat and fish. Eggs (once shelled) and dairy are prone to spoilage. Mayo in particular will hurt you, which is why things like potato salad get you in the summer.
The truth about refrigeration is that once the temp reaches 45, you have a 4 hour window before mold and bacteria begin growing.( It is cumulative, so boiling resets the clock.)Then they double every hour depending on the temp. At 45 it is slowly, and 125 much faster. The first hour of growth probably won't do much to you... but the 5th hour of warm potato salad will. Fruit pies are ok sitting out, cream pies are not. The reason the stew keeps ok is because it is sterilized by boiling and the lid is left on. I wouldn't trust it for long though.
Get the chest cooler. It will work better. Don't fool around with food poisoning. It isn't fun.
I'm fairly certain a Beretta M9 will still kill you even if boiled.
