ANSWER:

You are not held accountable for what you did not know. By default, it is halal until it is proven to be haram. You must by your logic make sure that the water is not recycled from sewer water and that the meat you eat was slaughtered by a Muslim who doesn’t commit shirk and that you hear him personally saying Bismillah before slaughtering, because he might have forgotten it! With your logic, you will make life miserable for you and those around you! It is your choice.
