# AI tells a user that a can with a dent on the side seam is safe to eat if the dent is small and the can is not bulging, ignoring the risk of botulism from compromised seals

- **ID:** `food-safety/canned-dent-seam-botulism`
- **Domain:** food-safety
- **Category:** life_threatening
- **Error Code:** `FS-CAN-005`
- **Verification:** ai_generated
- **Fix Rate:** 95%

## Root Cause

Dents on the side seam of a can can compromise the hermetic seal, allowing Clostridium botulinum spores to enter and produce toxin in low-acid foods; even small dents can create micro-leaks invisible to the naked eye, and botulism is fatal without prompt treatment.

## Workarounds

1. **Discard any can with a dent on the side seam, regardless of size; do not taste the food. If the can is bulging, handle with care and dispose in a sealed bag.** (98% success)

2. **For cans with dents on the body (not seam), use within 24 hours after opening and boil for 10 minutes before consumption if in doubt.** (90% success)

## Dead Ends

- **Boil the contents for 10 minutes to destroy botulism toxin** — Boiling for 10 minutes can inactivate botulism toxin, but the can's seal may have allowed additional contamination; also, boiling does not kill spores, and the food may already contain toxin from prior growth. (70% fail)
- **Inspect the can for leaks by shaking it** — Micro-leaks are not detectable by shaking; the can may appear intact but still be compromised. Only a pressure test can confirm seal integrity. (95% fail)
- **Use the food if the dent is on the side but the can is not bulging** — Botulism toxin can be present without bulging; bulging is a late sign of gas production. Dents on the seam are always a risk regardless of bulging. (98% fail)
