Several years ago I asked Dr. Shimanuki of the Beltsville Lab. about
bleach and AFB. The issue was whether dipping brood comb in bleach would
kill the spores. Dr. Shimanuki said they had tried it there at the lab
some years earlier but the method was not effective. The reason was not
that bleach did not kill AFB but that the bleach did not penetrate into
the comb to kill any embedded spores. I was left with the impression
that bleach did kill the surface spores.

This is at odds with David Knox's response. Someone might want to check
with Dr. Shimanuki again.
