First, it is always great to hear form you. Second, I apologize to the
moderators for the long quote.
I have no problem with your comments on wax since I agree with them, but
the issue is honey. We both say the same thing about treating with no
supers on and you note, as do I, that there is a time interval before
supers can be put on.
The problem with the study is the dye does not have a half life and it
was dyed sugar syrup so went directly into becoming honey. You could
check that colony years after the test and there may still be green dye,
especially in the end frames.
Some of the "chemicals" are not soluble in water or honey but they do
end up in wax.. There they can last for a long time because they are not
in contact with air or water. They break down quickly if exposed to air,
water and light. Which means they would not last long in nectar or
honey. so if the called for times were followed, the residue would be
near zero before the supers went on.
The approved chemicals in the EU, formic and oxalic, are soluble and
oxalic is in sugar syrup, like the dye. I am sure there is a time
specified by Finland to allow both to dissipate, which they do, so there
is no contamination. That has been shown in studies which measured the
level of the formic and oxalic acids over time. They drop to normal
honey levels.
You even allow antibiotics, but again, with a time after treatment
before supers can be put on. In this area, I think the US time is much
too short. I do not use them. Of all the things added to a colony when
instructions are followed, I think antibiotics could end up in honey.
They tend to be administered in spring while most other treatments are
after the supers have been removed.
It all gets back to the question, is organic honey purer than off the
shelf honey? So far the answer is no, which means all the honey
producers are following label directions. There may be honey that is
rejected by packers. I leave that to the commercial folks to address
since I do not know, but until another test comes along, we have one in
the US and one in Europe that say beekeepers are ethical and
responsible, be they organic or non-organic. That only makes sense,
otherwise you are out of business.
Which is my point.
