      Probably not, especially because some of the harmful stuff is actually just too much of the harmless stuff. We actually need a lot of bacteria and fungus to live, so we have to be careful about trying to kill it all.

      It would be difficult to only kill the harmful ones. There are lots of good bacteria, fungi and viruses if we made something that could kill them all then we may even milk ourselves. Humans need bacteria to live there are trillions of microorganisms on or in the human body. They outnumber our own cells 10-1. Most of the bacteria are found in our digestive system and they help us digest our food. They also help us make food eg cheese, bread, beer
