A brown color One indicator is the color. A brown avocado might not be as ripe as a green one or might need to ripen further. And if you see any browning on the skin, this is a sign that your fruit has been exposed to oxygen and should probably be eaten soon. An eggy smell The smell can also be a rotten egg. If there's a funky smell coming from your avocado, it could have gone bad. Also, watch out for black mold growing around the pit. This will usually show itself at least partially even before things go bad inside the flesh. A leathery texture Dryer avocados will generally spoil faster than those with higher moisture content. So if you're buying avocados from the store and they feel dry, they'll likely only last about 5 -7 days at best. As long as you're following proper food safety measures when handling and storing your avocado, it should be good to go for 2-3 days max if the pit is removed and you put it in the fridge. That's enough time to use in a few healthy recipes or even enjoy with a bit of salt and pepper.
