As others said, rewrites are common, but rewrites that include information that no longer exists is a bit odd. Typically, it means either Google is caching old content somewhere (including a duplicate copy of the page), or they're pulling from a directory somewhere, like the Open Directory. You could try the NOODP tag, since its harmless, although the hit rate is low (i.e. don't get your hopes up): If it were me, I'd put a unique snippet of the undesired meta description in quotes and do some exact searches on Google. Try to find out where Google thinks that text lives.
