These labs were remarked upon by a US collogue (biologist) back in 2017, about poor safety practices at the Chinese labs in question. I could dig up the quote if needed? The Chinese, along with pollution are way behind the West in environmental safety, and laws, and enforced laws. The China
hands that I have read indicate that this laxness is not uncommon, and resembles Europe and the US before the 1970's in enforced standards. The PRC has its "scandals" now as we have had them in our past. The "wet" market in question, near one lab, literally was a "wet" market in the sense that their prime product was
seafood, not birds, pigs, snakes, bats, etc.
I do note with a grin, that big pharma has moved in a big way to start to provide Covid-fighting pills to alleviate the infection, along with, of course the vaccines. I am pleased that they have progressed so far in getting these to patients. The FDA is supposed to meet on the 30th for advisory purposes.
