I recently watched the Video by the Killion's on comb honey production.
Their method was to leave a make a strong colony of bees queenless for a
period of 8 days or so during the early part of the honey flow.  Then after
removing all queen cells a few times during this time they introduce a young
mated queen.  During the queenless period the bees have stored a large
amount of nectar in the brood chamber and when the new queen is introduced
the bees immediately start moving a great deal of nectar into the comb honey
super to give the queen room to lay.
 
My question to the group is with all the Apistan residue that may be left in
the brood chamber (in the wax or whatever) from early spring treatment is
there any danger of the nectar that moves from the brood chamber to the comb
honey super being tainted?
