I don’t speak the tech language.

But is there a difference between BL4 and milling?

—An ABC reporter who writes on anthrax vaccine has privately confirmed that four labs have told him that under the electron microscope the sample looks just like material obtained by UNSCOM in Iraq. The Iraqi material was spray-dried BT. I have been told that such particles are distinguishable from milled particles. The US process did not use milling.

BL4 is the laboratory where anthrax might be produced.
(4 refers to the security level, which is the highest,
though I’ve heard rumours that BL5 labs may exist)

Milling is a technique that might be used to make the powdered anthrax.

Please follow the link I gave in #137 which gives an excellent summary of biological security.
