This food has black spots and cannot be eaten.

Black spots on tall bamboo shoots are generally caused by fungal infection or oxidation. These black spots will affect the eating quality. If there are only a few small black spots, you can trim them off and continue eating. If there are large black spots or mold on the surface of the bamboo shoots, it is not recommended to eat them, as this indicates serious contamination inside. When choosing tall bamboo shoots, it is best to choose fresh, clean bamboo shoots without obvious black spots, and wash and handle them carefully before cooking.
