This is pretty confusing. The fda website doesn't indicate whether the contamination is on the outside of the packet, or the inside of the packet. The identified microbe-Elizabethkingia meningoseptica- is a weird one that primarily infects neonates in third world countries, and otherwise caused some non-fatal infections in healthy folk-meaning that it is one of the opportunistic bugs that is routinely defeated by healthy immune systems.
It is one that I have never seen empirically, and it appears that we have some reliable antibiotics to treat it. Weird that the report is as sketchy as it is. And the rss feed from fda is spooky in its plethora of sketchily-described recalls.
