How to Tell if Mango is Bad – 8 Signs

In my last piece I wrote about signs to look for in ripe mangoes, I explained those signs and how to identify them. Like any other fruit, mangoes have a fixed freshness time and can get rotten or bad if not kept properly or not consumed within a particular period. 

There are unique ways to tell when a mango has gone bad or rotten. Below, I have explained eight tips to help you recognize a mango that has gone bad.

8 Signs that Shows a Mango has Gone Bad 

1. Dripping Juice

If the fluid is seeping out of a defected mango skin, I recommend that you toss the mango away immediately. If you notice liquid dripping out from its bruised skin, then it is certain that the mango is rotten. 

2. Wrinkly skin 

In my article on ripe mangoes, I stated that ripe mangoes often develop creases on their skin. When they decay and deteriorate, the creases get deeper and surround a substantial part of the fruit. 

That implies that it has gone awfully bad and should be thrown away.

You can search for the wrinkles by softly caressing the mango’s exterior and sensing from its skin if there are any unusual indications. A wrinkly mango is an indication that the mango has gone bad. 

Avoid consuming such mangoes as much as possible, mainly if you see any other signs suggesting decay, and I will explain them in this article.

3. Appearance

Mangoes are known to have occasional brown patches and specks. These can sometimes indicate that the mangoes are mature and ready to be eaten. 

But when you glance at the outer part of the mango and notice these brown patches or the fruit seems to be strange, then it’s possibly gone bad, and you shouldn’t eat it. 

The exterior part of the mango can inform you of what’s happening on the inside of the fruit. The problem evolves when they develop into huge black patches that strive and grow deeper into the body of the fruit.

When you cut a decayed mango open, you’ll see that the inside is porous to feel and has a distinct, more intense shade than other ripe mangoes.

4. Scent

The smell you sniff from the mango might help you infer how ripe it is. 

Giving it a good smell near the stem region is the nicest strategy to check its scent because it will be more intense and give you the bigger picture of the condition of the mango and how it smells.

If the mango has a sharp, fruity, and delightful aroma, it is possibly fully mature and ready to eat. Yet, if it smells stale, alcoholic, or even partially bitter, it’s a sure sign that the mango is decayed and deteriorating.

Mangoes have a harsh odor as they begin to go bad because of their high sugar volume, which influences them to ferment normally, making a decayed mango taste as terrible as it smells.

Fresh mangoes will not turn brown unless they are sour or spoiled, and this is generally in one or more particular areas on the mango, not all over. When cut and stripped, mangoes do not deteriorate as noticeably as apples or bananas; instead, they retain their vital yellow-orange color.

5. Brown coloration inward

Mangoes get very soft when ripe, even softer than a ripe avocado. 

If they were plucked when they were green, they would steadily turn brown inside rather than ripening, and in such a situation, they have a very terrible taste. 

There’s absolutely nothing to do when this occurs except throw them into your garbage heap.

6. Molds developing

Mold is also another sign that shows that your mango is bad, and by now, I’m sure you know what is best to do with it. Yes, you have to throw it out—nothing else to do.

7. Maggots infested

A maggot is the larva of the popular housefly. 

Maggots have delicate bodies and no legs, so they look like worms. They generally have a decreased head that they can withdraw into their body. 

Maggots typically relate to larvae that exist on animals and plants’ deteriorating flesh or tissue residue. Some varieties eat healthy animal tissue and living plant entities.

It may actually be harmless to devour maggots themselves. Still, you may be vulnerable to whatever they have eaten or have been exposed to, and it could be nasty things, like feces or decayed flesh. These can affect your health in negative ways.

Fruit overrun with maggots is possibly rotten and filled with bacteria. 

Mango worms originate from the eggs of the mango flies or skin maggot flies, also known as Cordylobia anthropophagi. If offered the chance, they are parasitic larvae able to infest all animals and humans. 

Consequently, it’s best to throw such mango into the trash.

8. Insects

Naturally, where there are maggots, insects are not far behind.

Along with the earlier signs I have mentioned, rotten mangoes will also result in other oddities like insects, and the likes, which aren’t good for you in any case.

So be sure to throw it away when you notice any of these signs.


I know that Mangoes are addictive, owing to their very sweet taste and nutritional benefits.

But please, do not eat a mango enclosed in black spots, indicates even the slightest signs of molding, has a pungent and horrible odor or has insects.

That mango is undoubtedly bad for you, so throw it away and pick another.
