In this brief article, we will answer the question “Can you eat an overripe cantaloupe?” and discuss how long do cantaloupes last. We will discuss how to properly store cantaloupes and how to tell if cantaloupes have gone bad. We will also discuss what happens if you eat a spoiled cantaloupe.
Can you eat an overripe cantaloupe?
Yes, you can eat an overripe cantaloupe. There is no harm in eating an overripe cantaloupe as long as there are no signs of it being rotten or spoiled. So, it is very important to check if your cantaloupe is still edible or if it is already spoiled before consumption.
If you notice that your cantaloupe is rotten and spoiled, please do not eat it, and throw it out immediately! eating spoiled cantaloupe can lead to severe health problems (1-3).
An overripe cantaloupe will be very mushy and will taste a lot sweeter. Some people might not be a fan of this mushy, soft texture but even then you can use this overripe cantaloupe to make smoothies, salads and desserts.
How to tell if an overripe cantaloupe has gone bad?
You can tell if cantaloupe has gone bad by looking at different signs related to its appearance, texture, and smell, for example:
- You should first examine your cantaloupe’s skin and inside for the presence of mold, particularly fuzzy patches, or spots. You should not eat cantaloupe contaminated with molds as they produce potent mycotoxins that can make you very sick (4).
- Remember that cantaloupe that has gone bad will have a very soft and slimy texture. So, you should press your overripe cantaloupe with your fingers and check the texture. Remember that if it feels excessively soft or mushy, it is likely overripe and possibly spoiled.
- Also check if your overripe cantaloupe emits a foul, pungent, or unpleasant smell when you cut it, it is a clear indication that your cantaloupe is spoiled. You should not eat it and throw it out immediately!
- You should also check if your cantaloupe is damaged to where the stem is connected. Be aware that different foodborne pathogens can infiltrate a damaged stem region and contaminate your cantaloupe (1-3).
You should always check these signs before eating your overripe cantaloupe. Remember that it is always best to prioritize caution and dispose of your cantaloupe to prevent potential health risks.
What happens if you eat a spoiled cantaloupe?
You should carefully inspect the cantaloupe before eating if you suspect that it has gone bad because eating contaminated or spoiled cantaloupe can result in food poisoning due to the presence of harmful pathogens including E. coli O157:H7, Listeria monocytogenes and Clostridium perfringens (1-4).
The symptoms of food poisoning are abdominal cramps, vomiting nausea, diarrhea and headache. In severe cases, hospitalization may also be necessary (5-7).
If you can not tell if cantaloupe has gone bad then go with your gut feeling and throw it out because it is better to be safe than sorry.
How long do cantaloupes last?
Whole cantaloupe can last for 5 to 7 days when placed on the countertop or in the pantry (8).
If you store the whole cantaloupe in the fridge, then it can last for about 2 weeks. Once it has been cut, it should not be placed on the countertop for more than 2 hours.
This is because bacteria can start to grow on it and can spoil it. You should store the cut up cantaloupe inside the fridge where it can last for about 4 to 7 days (8).
If you have bought an unripe cantaloupe, then it should be placed on the countertop until it ripens.
How to properly store cantaloupes?
You can place whole cantaloupes on the countertop or in the fridge. Keeping them in the fridge extends their shelf life so it is a good option for when you want to store your cantaloupes for a couple of weeks.
Before placing them inside the fridge, place them inside an airtight bag so that their aroma does not spread inside the fridge and into other food items.
When you have cut up your cantaloupe, place it inside an airtight container or a ziploc bag then place it inside the fridge especially if you do not plan on eating it within the next two hours. As discussed above, bacteria can grow on it and spoil it.
Unripe cantaloupe needs to be placed on the countertop or in your pantry so that it can ripen. Once it ripens, then you can either place it in the fridge or the countertop depending on when you want to consume it.
Conclusion:
In this brief guide, we answered the question “Can you eat an overripe cantaloupe?” and discussed how long cantaloupes last. We discussed how to properly store cantaloupes and how to tell if cantaloupes have gone bad. We also discussed what happens if you eat a spoiled cantaloupe.
