There are 2 basic genera of bacteria that form
endospores which are resistant to decomposition,
disinfectants, and boiling.  These 2 genera are
Clostridium and Bacillus.  Bacillus cereus is a
bacterium that can survive in rice during the cooking
process and cause disease after being boiled.  AFB is
a bacterium in the Bacillus genus as well.

Boiling water reaches a maximum temperature of 212 F
(100 C) at normal atmospheric pressure. In the
increased pressure of an autoclave or pressure cooker,
water/steam temperatures reach 250 F.  20 minutes of
pressurized steam at 250 F is sufficient to sterilize
clean surgical equipment for medical uses.

In New Zealand, AFB positive woodenware can be cooked
in paraffin to kill AFB spores.  This can get hotter
than boiling water which has a limit of 212 F.

I did read the article concerning beach killing of AFB
spores.  I read this with reservation and feel that
this would be adopted in New Zealand instead of the
paraffin method if it was really reliable.

Better not count on bleach to kill any endospore
producing bacterium, especially when coated with a
lipophilic substance like propolis.

You might consider ethylene oxide, which is credited
with killing endospores and is an approved method of
medical sterilization.
