Despite its extreme potency, botulinum toxin is easily destroyed. Heating to an internal temperature of 85°C for at least 5 minutes will decontaminate affected food or drink.
Can botulism survive boiling?
botulinum are heat-resistant, the toxin produced by bacteria growing out of the spores under anaerobic conditions is destroyed by boiling (for example, at internal temperature greater than 85 °C for 5 minutes or longer).
Does botulism die when exposed to air?
Despite its deadly nature, BoNT is destroyed easily by heat. A temperature of 80°C for 30 minutes, or 85°C for 5 minutes, effectively denatures the protein, inactivating the toxin. Direct sunlight can deactivate toxin within 1 to 3 hours. Simple exposure to open air can deactivate toxin within 12 hours.

Why is botulism so rare?
Spores are not killed by boiling, but botulism is uncommon because special, rarely obtained conditions are necessary for botulinum toxin production from C. botulinum spores, including an anaerobic, low-salt, low-acid, low-sugar environment at ambient temperatures.
