This above is not true. If bees are treated with things like fluvalinates or
antibitics these will get easily into the wax of the supers ( fluvalinates)
and honey
(antibiotics) even in cases when supers are not on during medications. The
supers get these residues by the bees.
The Danes had a nice stude a few years back They coloured winter feed sugar
at fall green with a food grade dye. Let the colonies overwinter and develop
the normal way in spring and took first extracton of pale green coloured
honey from supers that were added in spring. Bees do not use stored food
without mixing it with the incoming nectar that they are handling at that
moment. As the brood area is expanding in the lower boxes they will empty
the winter feed cells and some part ot it will be stored with the new honey
into supers. This will of course depend on the situation. Will be more if
the hives gets throught the winter with lots of stores and very little in
hives that fall near starvation before summer flow.
Also some part of wax is taken from below and mixed into cappings and walls
in new boxes. Also ropolis is moved this way. And the bees travel by foot
in the hive passing from brood boxes into supers. Travel stain in supers is
known by most of the beekeepers. Just walking from old frames into new will
carry some residues.
It is very good practice treating only when supers are not on. It will
reduce dramatically the residues in supers. But it is an illusion to think
that this will mean 0 ppm residues in wax and honey of supers. Bees use all
that they have and mix it all the time with what is coming in. Remember the
studies with radioactive markers. After feeding only few bees almost all
bees had the marker into them after only few hours.
These abowe are among the reasons that state in Finland that bee hives
treted with antibiotics ( only tetracyclines allowed) can not be harvested
for the honey collected within next 100 days. Not even form supers that were
not on during the treatment. In our short summer this means that if hive is
trated in spring honey from the whole summer can not be sold for human
consumption.
