Can you eat taro once it has sprouted?
Generally, whether taro can be eaten after sprouting depends on its specific condition. If in doubt, it is recommended to discard it to ensure safety. The detailed analysis is as follows:

If the taro has only sprouted slightly, with small sprouts and no signs of rotting, mold, or blackening on the skin, and when cut open reveals firm texture, no unusual odor, and no hollow or soft spots inside, it is generally safe to eat. In such cases, sprouting merely indicates that the tuber is converting its nutrients to support sprout growth, without producing harmful substances. Before consumption, thoroughly remove the sprouts and a small portion of the surrounding tissue, and ensure the taro is fully cooked. Although the taste and nutritional value may be slightly reduced, it remains safe to eat.
However, if the taro has heavily sprouted, with large, robust sprouts accompanied by skin decay, mold, or slimy residue, or if the interior appears darkened, brownish, hollow, mushy, or emits an unpleasant smell when cut open, it should not be consumed. Severely sprouted taro is prone to bacterial growth or the production of substances harmful to health. Eating it may irritate the gastrointestinal tract and cause discomfort such as abdominal pain and diarrhea; continued consumption could pose serious health risks.
When storing taro, keep it in a cool, dry, well-ventilated place, away from direct sunlight and moisture to slow down sprouting and spoilage. Once sprouting is observed, carefully examine the overall condition. For safety, if there is any uncertainty about edibility, it is best to discard the taro.
