Not regular flu they dont.
Uhhhh, yeah they do.
I built clean rooms for Applied Bio, Celera, UCSF Bio Labs Parnasus(Monkeys are used in this lab), Elan Pharma, Genitope, Guidant, Intermmune, Abbott Labs and many others(just went through my customer list).
We have to go to classes on some of the work these places do, understand the risks and a bunch of other legal mumbo jumbo.
The funny part is we build these rooms many times before they begin any work with cultures and such.
Just so you understand there are Freepers who know what business we are in and will absolutely verify what I’m saying.
