AEMSA is a professional trade association,
not an independent regulatory body nor a consumer protection agency. They set standards for their (voluntary )members to follow, and they represent their members. The member dues are voted for by the members themselves. Yes, a lot of mom and shop vendors can't afford the seven hundred odd dollars a month it costs to be a member but considering they have less than thirty members that is not a lot of money they bring in monthly considering what they do ( attend fda workshops, check member facilities for verification etc ... ).
Can they guaranty that that there are no diketones in the flavors their members purchase to put in their
juice ? No. But they are trying to keep them out and the individual members themselves take different steps to that end. Some members test every
finished juice they market ( like the two mentioned earlier in the thread ). Others try to verify as much as they can with the flavor vendors. A heck of a lot better than vendors who
knowingly put diketones in their juice because it tastes good and they will make a profit in the short run. The vast majority of these vendors have absolutely no expectation to be in business post fda regulation.
The reality is there
will be some regulations put in place one way or another. If a vendor could not afford $ 700 a month AEMSA membership how could they expect to afford complying with the fda regs ? You can think what you want about AEMSA. I haven't fully made up my mind, but i don't think the monthly dues are exorbitant considering what they do and the tiny percentage of vendors that are members.
I have no expectation that my juice be completely safe if i purchase from an AEMSA vendor, but i would feel a lot more comfortable purchasing from a vendor that tries to adhere to some standards as opposed to the guy mixing his his juice in the back room of his store or in his basement.
