Why is ingesting fecal matter dangerous even though its just stuff from your body?
In: Biology
no you’re right. poop in your water, if it comes from a healthy person, is NOT any more dangerous than like, eye snot.
but poop is also a great way to travel if you’re a parasite. you live in water, someone drinks that water, and then they shit their brains out back into that water, which makes you really mobile and lets you infect a ton of people.
fecal coliform bacteria therefore act as signs that you’ve got poop in your water, which tells you that IF that someone who pooed in your water is sick, you better watch out.
tldr: good poop fine, but bad things evolved to live in poop, so bad poo gets you real sick.
