>>Surely if the bees were working a contaminated crop then they would 
entomb all of it -whole combs; is that what is being seen?

I have never seen more than perhaps 5-10% of pollen cells entombed.  I 
have seen it specifically in new comb from hives that pollinate almonds 
as well as hives that pollinate raspberries after one season.  I have 
pictures if anyone is interested.
