I've always thought antibacterial soap was a bit ridiculous. Bacteria are everywhere, most are harmless, and they reproduce rapidly. It seems then that killing a bunch with a soap that "kills 99.9 percent of bacteria" only creates churn in the environment-- unless it targets only the harmful bacteria, which I doubt.
To me, bacteria are just another force of nature like wind or chemicals: harmful or harmless depending on context more than anything else. Table salt will kill you if you ingest 300g of it, but small amounts are healthy. Example with bacteria: E. coli, which is beneficial in its right place (the gut) but harmful elsewhere.
You must've made a typo with your salt. 1500 mg is a reasonable daily intake.
Also, with the bacteria it isn't so much where they are as it is that there is usually a lot of variation within each species, with only some of the varieties being virulent.
