The Demon in the Freezer is by Richard Preston, author of The Hot Zone
A chunk of "Demon" was excerpted in the New Yorker. It is an unsettling read.
You may also be thinking of Biohazard by Ken Alibek, which details his bioweapons research and production in the old Soviet Union. At one point, Biopreparat was manufacturing some ten tons of weaponized smallpox per year.
We live in interesting times.
Yes, I tend to agree.
