Natural, like old age or scared to death by a barking dog? Sure. Anything else, no.
If it's been out dead for longer than 30min-1hr it's risk is getting higher. But then again, we live in a world that sees a lot as wrong or taboo. If you want to and have built up a good immunity to it, why not?
I eat 'raw' bacon, from the store, it's smoked, I call that cooked, lol. Idk, that's from growing up, my family eats it like that, I've never gotten sick from it. They say being afraid of bacteria and using meds for everything is causing super resistant diseases. I'm pretty sure all those homeopathic meds used to work, back before all these drugs showed up.
