I am highly allergic to ragweed pollen. Have seen photos of bees foraging on this 
plant.  One year I ate a small piece of "comb honey" from an exposed colony which 
we harvested, and I got severe allergic reactions (stomach cramps, hives all over 
my body, itching all over).  I  susopect that there were a few pollen cells containing 
high amounts of ragweed pollen.
