What will be the purpose in doing that?
It comes from poop that gets into the food chain and went to one animal and then I think unfortunately flipped from animal to man. I think the poop was in China. So what exactly is it that we need to know more than what we already do?
Folks seem to agree it originated in China from poop and barnyard animals. Transference occurred and we are where we are.
Well it will keep the countries occupied investigating. Hopefully they will all arrive at the same conclusion or there will be bickering among them just as there is always bickering among "experts".
Will their investigative findings be made available to the rest of us? Post it on the internet for us to access? Or if the findings are embarrassing will we never hear another word about it? We'll see.
Does it really matter where it came from? It's here - now. Determining where it came from will only serve to lay blame. Nearly all diseases are spread from unsanitary conditions (like, hypothetically, growing lettuce downhill from a slaughter house). It costs money to change, and no one is willing to sacrifice one penny of their profits to change.
