Germination indicates that yam has begun to carry out life activities. Although it does not produce harmful substances such as solanine like potato germination, the nutrients in it have been reduced, so it may have an impact on the human body. If you really want to eat, you can dig out the sprouted parts and eat them.
Yam is best placed in a cool and dry corner, which can last longer. Or directly stored in the refrigerator without cleaning, and the problem of yam germination can also be avoided. It's hot in summer, so you'd better finish eating yam in two months.
