How is food safe and hygienic when you eat it, but not when it comes out the other end? What’s the process?

First your teeth break it down into a slurry, and then that slurry is sent into your stomach where it is chemically and physically broken down even further. Then it passes through your small intestines where most of the nutrient is absorbed, but not all of it because there is a lot that we cannot process. So our gut is filled with micro organisms that take advantage of this and break down the food even further. And in doing so they produce a lot of by-products that are toxic to us.
Poop carries bacteria and parasite that grow in your intestines which causes it to be unsafe and unhygienic. This includes E.coli and salmonella. Therefore when it has had contact with your mouth it can cause harm and a range of symptoms such as fever and vomiting etc. so it’s not safe to eat
Food isn’t really safe and hygienic automatically. We spend lots of time making sure animals are healthy, food is refrigerated, service workers handle it with clean hands and whatnot.
And as for poop itself it’s not actually that unsafe and unhygienic. But it comes out of you and can carry anything you are sick with to anyone else who touches it. So like if one sick person poops in the water supply, everyone who drinks from there is now sick. So from a hygiene standpoint you want to keep one person’s poop from spreading around and getting into other peoples mouths, same as you probably shouldn’t be spitting or bleeding onto other people either.
