There's a real chance I eat sterilized poop on a regular basis.

You probably do too. You should look at the regulations on how much mouse feces is allowed in your cereal grains.... Not to even mention how common eating pork intestines are...
There are some fancy kinds of coffee beans that are fed to monkeys, come out in their poop whole (but fermented) and then roasted and sold.
Let's be real here. The only reason poop isn't considered a viable food source is because it tastes nasty. Otherwise we'd have probably found a way to utilize it and cook with it.
As it is, a lot of animals are corophages.

We just aren't that desperate.
