OAV exposed honeycomb

[tjc1]

Lost two hives in late fall not long after an OAV treatment. Between them there are about 30 frames of honey. I am restarting two hives this spring (a package and a nuc). I figure once they get going, I can put a box of honey above each hive and they will be able to take care of it/protect it. But what about the rest? Seems like too much to put it all on new hives. Is it safe to extract any of it having been fumed?

This was pulled from: http://www.neurobiologie.fu-berlin.de/menzel/Rademacher.html which comments on the residue of OA in honey:

d) Oxalic acid was developed to the final-use stage as a drug in bees by the European Working Group for Integrated Varroa Control (CA 3686). In all EU countries, government approval is only given to a new veterinary medicament for use in treating animal diseases after the EMA, the European Union?s Agency for Evaluating Medical Products, has determined the maximum residue limit (MRL) of the active ingredient allowed in the final food product according to European legislation. This procedure is meant to protect consumers from toxicologically critical residues in foods resulting from medicines used on animals. For oxalic acid no MRL was available. The MRL establishing procedure was started in cooperation with A. Imdorf (Agroscope Liebefeld-Posieux, Swiss Bee Research Centre), J.M Poul (Agence Fran?aise de S?curit? Sanitaire des Aliments) and A. Wibbertmann (Fraunhofer Institute for Toxicology and Experimental Medicine), carried out as a joint project of many European countries and successfully finished in December 2003: oxalic acid was listed in Annex II of Council Regulation (EEC) 2377/90 (Rademacher and Imdorf , 2004). This means that the substance is evaluated as not dangerous, and no residue limit is needed to protect the consumer. On this basis every European country can apply for approval and the Concept of Integrated Varroa Control, as recommended by the scientific institutes for bee research, can legally be implemented. It was the first time that scientific institutes and beekeeper organisations worked together on a European level to establish the legal basis for drug approval in bees.

This IS European legislation, and not that of the US, but I hope it can still be used for guidance.

You can always extract, put the honey in the freezer and feed back to the bees as needed.
Personally I would try some because OAV treatments don't penetrate cappings. But I've been known to do things that other poeple wouldn't dream of doing. Like beekeeping.

Good info LJ & good point rwlaw

I'd extract and use it for the bees and me, too.

Maybe all of us should reread the label of this product Oxalic Acid Dihydrate . That is approved for the USA.The label is very specific that it is only to be used.  something to remember the state will tell you the label is the law. If you are using a Oxalic Acid. That does not have this label in the USA. Then it is not approved in the USA Whether you like it or not.
At can be found at

      Oxalic acid is only to be used on brood Chambers and not honey supers in the USA

Here we go again.....

I'm guessing the original poster tjc1 does not know Oxalic Acid Dihydrate. The one that's labeled for honey bees has only been legal in Massachusetts maybe 2 months and in Connecticut for about 6 weeks. And he's talking about last year. Plus Oxalic Acid has has to be approved by the farm board every year in the state of Massachusetts.

It's true - I hadn't realized that it was not certified for MA when I used it the first time last fall - I thought that I had read that it had been certified for use in the US... Was surprised when I got the news from my local club that MA had just granted certification over the winter...

[Jim134]

         Once the EPA certified chemical that can be used in USA. It Has to be approved to be used in each individual state. Like they say that's just the way it is.
There are two things I would do that honey. One would be for self use. The other would be 2 feed bees. I would not sell it.

tjc--The fact that you even asked, answers your question....
