I've gone to whole foods as well and I think it has something to do with the fact that the nuts are old and sit on the shelf for awhile as many people buy nuts from regular stores because they're cheaper there. check exp. dates on products. whole foods has a policy where they will take old foods back if you are not comfortable. i had an issue a few years back with whole foods market bin/bulk foods. I was finding alot of filth in that stuff and I encouraged them to clean their bins out more often.
