For a while now I have been kicking around the idea of conducting an experiment to see how much oxalic acid is contained in honey from hives that I am treating. I was going to test two hives. Hive one was going to have a series of five to seven treatments a week apart. Hive 2 was going to receive one treatment. The reason for this is I have done a series of treatments when I have brood and I have treated with m a q s late summer and a one shot of OA in the winter. I have only contacted one Laboratory but was shocked at the price they would charge. I was quoted $2,000 for one sample. Subsequent samples would be cheaper but I didn't bother to ask how much. The lab explained to me the challenges in conducting this test. I have to admit I did not really understand most of it not being a scientist. I am going to call around to see if I can get a more reasonable price. I am posting this for informational purposes but I am curious if anyone knows why this is so expensive and complicated. The amount of oxalic acid in vegetables such as spinach and kale is readily available so it can't be that hard or expensive to test I would think. I am interested in hearing from any scientists about this. My motivation for doing this is mainly personal and curiosity and I was hopeful perhaps I could advance the knowledge of OA and it's residuals in honey. On the personal side I extracted a bunch of deep frames in the spring and got 80 lb of absolutely delicious honey that I would love to eat but it looks like I will give back to the bees this fall unless I can assure myself that it is safe to eat. I do not sell honey and would only use this for personal consumption if the test results came back low. Any scientists out there? J
