Q&A for How to Tell if a Kiwi Has Gone Bad

If you see darker green, mushier spots inside the kiwi, it's gone bad.

If a kiwi's smell is off at all, then it most likely has gone bad. I would throw it out.

It's probably a little mold. You can choose to cut that part out and eat the rest, or throw away the whole kiwi; it's up to you. If the mold is on the inside of an already-cut kiwi, it would probably be safer just to throw the kiwi away; mold can spread quickly inside the soft and wet inside of a kiwi.

No, it is still edible. Only if the kiwi has white mold near the pulp or it has dark spots on the outside it is bad.

If a kiwi fruit is hard it's probably underripe - it's safe to eat, but you'll probably have tough time cutting through the white part in the center.

Some kiwifruits are yellow naturally, so provided you've purchased yellow kiwifruit, than you're fine to eat them.

If the kiwifruit smells fermented, then it has gone bad and it should not be eaten. Toss it into the compost and get a new, fresh one for dessert.
