What temperature kills botulism?
240°F to 250°F
botulinum can only be destroyed under proper temperature and pressure for sufficient time. Temperatures in the range of 240°F to 250°F (115°C to 121°C) are needed in order to kill spores (USDA 2015).
How do you test for botulism?

You can help prevent botulism by following safe food handling practices, such as:
- refrigerating leftovers promptly.
- using foods that are stored in oil within 10 days of opening.
- keeping foods stored in oil, like vegetables and herbs, in the fridge.
- making sure products marked ‘keep refrigerated’ are kept in the fridge.
How do you prevent botulism in canned food?
By cooking under pressure, you can increase the temperature of boiling water from 100°C (212°F) up to 116°C (240°F). This is the minimum temperature necessary to destroy botulism spores, and the only way to guarantee safe canning for food items such as vegetables, meats and seafood.
