It was pointed out in another thread that botulinum toxin, the bacteria waste that causes the condition of botulism will not be denatured - rendered harmless- by a 10% bleach solution until after 10 to 15 minutes of contact time.
There are rather a large number of different strains of bacteria within genus
Clostridium species
botulinum that produce botulinum toxin.
A presumably partial list is here:

Note the strains are divided by the serotype of the toxin produced.
I shall edit this post with another suitable reference when I have current correct information regarding ultimate disinfection
under household conditions. Most of the chemicals we use in the hospital I would not want in my home even it was legal.
I shall poke around some more for:
A) time and temp in a dry oven to kill or render harmless anything and everything currently known to science (it used to be 350°F for 30 minutes)
B) exposure time with __% bleach solution to kill or render harmless...etc, used to be instantly with 10% bleach. We haven't had any fist fights in the break room yet today ;-)
EDIT: post one edited to reflect review status.
