Botulism dies when cooked to 240ºF/116ºC, or boiled for 10 minutes.
Salmonella dies at 160ºF/71ºC.
E.coli dies at 160º/F/71ºC.
Typhoid dies when boiled.

Boiling takes place at 212ºF/100ºC

But if the water was bleached and not opened, how would contamination occur? There is no such thing as spontaneous generation.
