Go beyond the forum and do some more digging and you'll find a lot more information about how far short some of these organizations fall from their original good intentions. [Not trying to "out cynical" you expat, but this is assuming the 'original good intentions' were not just a white wash of the true intention to take advantage of consumer trust...just sayin'.]
Some certifiers seem to be no more than toadies for the big multi-nationals. It seems some of the certifiers are more geared to helping the big coffee roasters -- think Nestle, etc. -- tick their marketing boxes than they are concerned about the farmers. I guess it is more about helping the consumer give themselves a pat on the back for being good, caring citizens. The reality seems to be that for the most part the growers are still getting screwed by the fairtraders, et al. (Did I mention that I was cynical about all this stuff?)
As to organic coffee, coffee containers coming into their destination port, or when leaving their port of origin, are fumigated to kill any bugs in the shipment. For non-organic coffee the fumigation process is pretty harsh. For organic produce an ozone fumigation process is SUPPOSED to be used but in most of the third-world ports, even in first-world ports, I question how diligent the stevedores are about using that process or even if it is affordable or sustainable for the third-worlders. When organic produce is in the same container as conventionally grown I'm not sure what the fumigators do. [Good point! I hadn't thought of that.] (Think about the guys actually doing the work, not how it is 'supposed to be done'.)
Ok, time to take my cynical self and go roast some [Organic? Fair Trade?] coffee.
