Is it safe to eat an avocado after 3 days?

Yes, it is generally safe to eat an avocado after three days, provided it has been stored properly and shows no signs of spoilage, such as mold, an off smell, or excessive browning. If the avocado is still firm and has a normal appearance, it should be fine to consume. However, if it has become overly soft or mushy, it may be best to discard it. Always use your judgment and inspect the fruit before eating.
