Root Cause

Botulism toxin (Clostridium botulinum) is not neutralized by pH adjustment after toxin formation; only prolonged heating above 185°F (85°C) for 5 minutes or pressure canning at 240°F (116°C) destroys the toxin.

Workarounds

  1. 95% success If any can is bulging, leaking, or has off-odor, do not open it. Wrap in plastic, place in sealed bag, and dispose in trash that will not be scavenged. Wash hands thoroughly with soap and water.

  2. 85% success Boil the food in a saucepan at a rolling boil for at least 10 minutes (at altitudes above 3000 ft, add 1 minute per 1000 ft). This destroys botulism toxin if present. Use a thermometer to ensure 212°F.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Acidification after toxin formation does not destroy preformed botulism toxin; it only prevents future growth.

  2. 80% fail

    Botulism toxin requires 5+ minutes at 185°F (85°C) or 10 minutes at 176°F (80°C) for inactivation; 1 minute is insufficient.

  3. 60% fail

    While correct for canning, this is not a practical fix for already-canned food that is suspected; the food must be discarded.
