Quoting from Robin Dartingtons mail referring to EFB/
"Even if resistant bees were introduced, all infected equipment would still need to be destroyed as
it apparently remains infectious for at least 40 years and not all bees will be of new resistant
strains (unless there was a government restocking programme, which I cannot believe).  So we must do
all possible to stop EFB in UK expanding into a crisis."

Referring, admit ably to an old text - E B Wedmore, "A manual of Beekeeping" 1948. ISBN 0 905652 01
0

Page360, it states the following:
Destruction of EFB in Honey: 1. at 80°C takes 10 minutes
                                                   2. in the shade takes 8 months
                                                   3. in direct sunlight takes 4 hours

Destruction of EFB in Water: 1. at 65°C takes 10 minutes
                                                   2. 2% Carbolic takes 6 hours
                                                   3. in direct sunlight takes 6 hours

Destruction of EFB in Dry air: 1. in dark conditions takes 1 year or more
                                                    2. in direct sunlight takes 35 hours
                                                    3. at 100°C takes - unknown

Any comments and updates would be welcome!, especially taking into account that Robin states that
material remains infectious for at least 40 years

Wedmore is the only text that I have that mentions any periods for infectious state.
