You bought avocados on Monday and by Wednesday they are perfectly ripe. You only use one. Now it is Friday and you are wondering whether the other one is still good. Or you halved an avocado last night, used half, and wrapped the rest in plastic wrap. What is still worth eating?
Do avocados go bad?
The short answer: Yes, and faster than most whole produce you buy. A whole ripe avocado lasts only 1 to 2 days on the counter before becoming overripe. A ripe whole avocado in the refrigerator lasts 2 to 5 days. A halved avocado lasts 1 to 2 days in the fridge with the pit in and lemon juice applied. Cut or diced avocado lasts 3 to 4 days refrigerated in an airtight container. Brown flesh is usually oxidation, not spoilage. Grey, stringy, or slimy flesh means discard.

Key Takeaways
Whole unripe avocado: counter, 3 to 5 days until ripe
Whole ripe avocado: counter 1 to 2 days; fridge 2 to 5 days
Halved avocado (pit in, lemon juice applied): fridge, 1 to 2 days
Cut or diced avocado: airtight container, fridge, 3 to 4 days
Guacamole: plastic wrap pressed directly on surface, fridge, 1 to 2 days
Brown flesh: usually oxidation, safe to scrape off and eat if flesh underneath is green
Grey, black, or stringy flesh: spoilage, discard
Do not store avocados submerged in water: FDA warns this allows Listeria to infiltrate the pulp

Shelf life figures for whole avocados per Michigan State University Extension and the National Center for Home Food Preservation. Cut avocado figures per NCHFP. Ripe whole avocado counter life is very short because the avocado continues ripening after it reaches peak texture.
Brown Flesh: Oxidation vs. Spoilage
This is the question that sends most avocados to the compost unnecessarily. Brown flesh in an avocado is not automatically a reason to throw it away. The distinction matters.
Brown from oxidation happens when the cut flesh is exposed to air. Oxygen reacts with enzymes in the avocado pulp and turns the surface brown. This is the same process that browns a cut apple. The brown layer is aesthetically unpleasant but safe to eat. In most cases, scraping or slicing away the thin brown surface reveals perfectly good green flesh underneath. The avocado is fine to eat.
Grey, black, or stringy flesh throughout is different. When the flesh is grey or black all the way through, wh
