Short answer
Yes, spoiled bamboo shoots pose added risks. Raw or fermented shoots contain cyanide-producing compounds, and mold growth introduces toxins. Signs like vomiting, diarrhea, or weakness may appear within hours. Cooked fresh shoots are safer, but discard any that smell sour or have slimy spots. Call your vet if symptoms develop.
