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.

罐头侧缝上的凹痕可能破坏密封，使肉毒梭菌孢子进入并在低酸食品中产生毒素；即使小凹痕也可能造成肉眼不可见的微泄漏，且肉毒杆菌中毒若不及时治疗会致命。

Workarounds

  1. 98% success 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.

Dead Ends

Common approaches that don't work:

  1. Boil the contents for 10 minutes to destroy botulism toxin 70% fail

    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.

  2. Inspect the can for leaks by shaking it 95% fail

    Micro-leaks are not detectable by shaking; the can may appear intact but still be compromised. Only a pressure test can confirm seal integrity.

  3. Use the food if the dent is on the side but the can is not bulging 98% fail

    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.
