Can botulism be killed if cooked?

Yes, cooking can kill botulism, specifically by destroying the potent neurotoxin, but you need high heat: boiling home-canned low-acid foods for 10 minutes (plus extra time for altitude) deactivates the toxin, while the heat-resistant spores themselves need a pressure canner's extreme temperatures (around 240°F or 116°C) to be destroyed, notes the Centers for Disease Control and Prevention and UC Agriculture and Natural Resources. Freezing does not destroy the toxin, so proper canning and cooking are crucial.
