> I liked to eat bits of raw meat while my mother cooked and always thought we rinsed the vegetables only because they taste and look better without the dirt and small bugs.

With healthy livestock the chances of getting anything from eating raw meat are very low. With healthy livestock is a pretty big caveat though. Most people throughout history have had parasites, never mind animals. Industrial agriculture has the benefit of antibiotics and other medicines so most livestock is healthy. My biology lecturer in college said he wouldn’t eat fish, poultry or pig raw, everything else was basically ok. Fish because wild fish are crawling with parasites, poultry because salmonella is everywhere and pigs because of ringworm.

Vegetables are safe if they haven’t had unfermented on them recently but taking the time to let manure rot doesn’t always happen in places where that’s the only fertiliser you’ve got. If you can buy nitrogenous fertiliser by the bag you’re overwhelmingly going to be fine but generally safe food is not natural, it’s the product of work.
