So, how do you check if your sweet potato has gone bad? First, take a gander at the color - if it's developed any weird green or black spots, it's probably time to say goodbye. And, let's be real, if it's started to shrivel up like a prune, it's not exactly going to be the most appetizing thing to eat.
Another thing to check is the texture - if your sweet potato has become all mushy or squishy, it's likely that it's broken down and is no longer safe to eat. It's kinda like when you leave a banana out for too long and it turns into a brown mush - not exactly the most appealing snack! But, hey, at least it's a good excuse to go buy some more sweet potatoes, right?
