From what I understand the active part of the germ lives for nine hours after a cough or sneeze. That being said it seams as if they keep changing the stats all the time. I'm expecting some mail very soon and have zero concerns along those lines.
If your brewing your own raws then you should already be handling your goods like a real lab. Sterile conditions, disinfectant, sanitizers, gloves ,masks, etc..
If your real paranoid when you pack arrives wipe everything down with bleach wipes. At one point you will be heating your raws which should kill off any bacteria.
Got a package about 2 weeks ago that didn't have any delays and came quick from TP but things might have changed since than. I haven't been concerned but still plan on wiping it down with alcohol.
