My Doctor's kids play in the mud and ingest a lot of things accidentally. He lives on former "traditional" dairy farm land. The family finally sold it after they just could not compete with the big time/high scale commercial outfits.

He said the earth/dirt smells almost wonderfully delicious.

He said this "anti-microbial" trend/fad/tendency is going to collapse our society faster than any war will. It is coming. The assurance it is going to happen is approaching "1" in the future and probably much sooner than global warming will kill us.

Unless we get/develop "Star Trek" type medications that target very specific things... we are indeed doomed.
