I lost a hive to SHB this year that had 2 full deep supers. I froze all the frames and caught it early enough that very little honey is fermented. Subsequent to this I lost some nucs in the same apiary to AFB. . I planned on feeding this honey to some hives but am now concerned it could contain AFB spores. I know I can check for the spores with a microscope o a brood frame by dissolving some of the scale left by dead brood but I've not been able to find a method of scoping the honey. Any ideas?
