Pretty certain the coffee roasting process takes care of all of the germs and mold. Either way, if this guy really cared about the conditions his food was in before it reached his table, he'd be limiting his diet significantly. Agriculture is dirty work. Some of it is dirtier than others, especially if we're talking about animals.
Case in point, pork. Ever been on a pig farm? Not a farm with pigs, but an actual pig farm? I know a guy who owns one and he tells me those fuckers are dirty, and I don't mean wallowing in mud dirty. I mean if you go into a building with 1000+ pigs, you will be overwhelmed by the smell. If you're there for any length of time, it permeates your clothes and your skin and you won't feel clean until you scrub like crazy. Know what smells delicious though? Sausage. I rest my case.
