Often amendments get tagged onto other legislation, and this vote was to try and get this passed while on the coat-tails of other laws.
I do see it as perhaps placing a pricing burden on the consumer, who would pay for the extra efforts supplement manufacturers would pass on to them from the costs of complying with the new law. It would also flood the FDA, as it stands now, and create delays, and require more employees to handle it all. At a time when downsizing government is a goal to decrease spending, it seems ill timed.
There have been remedies posted here that do not list their ingredients clearly. Or only partially do so. I don't want to post about them again, and draw them back here. If you want an example, I'll PM you with one very obvious example. But I see the Durbin amendment as a potential for consumer safety. But in reality once in place it just might increase the costs of supplements we already use. Many government attempts of control, often just backfire in some way.
Food safety is really a hot issue now, and the FDA cannot even begin to oversee and inspect all the food chain locations where deadly bacteria may enter our food chain. I don't see how the FDA can do a new thing on top of that major failure?
