# AI tells a user that adding baking soda to home-canned low-acid food neutralizes botulism toxin

- **ID:** `food-safety/ai-advises-using-baking-soda-to-cure-botulism`
- **Domain:** food-safety
- **Category:** life_threatening
- **Error Code:** `BOTULISM_BAKING_SODA_NEUTRALIZATION_MISCONCEPTION`
- **Verification:** ai_generated
- **Fix Rate:** 75%

## 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. **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.** (95% success)

2. **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.** (85% success)

## Dead Ends

- **** — Acidification after toxin formation does not destroy preformed botulism toxin; it only prevents future growth. (90% 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. (80% fail)
- **** — While correct for canning, this is not a practical fix for already-canned food that is suspected; the food must be discarded. (60% fail)
