It says the e-mail was in January 2012 - during crab season probably.  Frostbite could be a definite possibility that time of year.  They send the processor workers into the hold of the crab boats to load the brailers - it's pretty cold work.  Also the processing work where they cut them down, gill them pack them and load them into blast freezers is pretty cold.  I worked at a clinic in nearby King Cove, and while I don't remember seeing frostbite, I saw lots of injuries, and I could see how frostbite could happen.
