Yes, cut watermelon can go bad.
Cut watermelon, like any fresh produce, is susceptible to spoilage. The primary reasons for this are bacterial growth and enzymatic activity, both of which accelerate once the melon is cut and exposed to the air.
How to Tell if Cut Watermelon Has Gone Bad:
- Appearance: Look for a mushy or slimy texture on the surface. The color may also appear dull or discolored.
- Smell: Spoiled watermelon will often have an off or sour smell.
- Taste: If the watermelon tastes sour or fizzy, it's likely gone bad.
Factors Affecting Spoilage:
- Storage Conditions: Cut watermelon should always be stored in the refrigerator. The warmer the temperature, the faster it will spoil.
- Exposure to Air: Exposure to air promotes bacterial growth. Tightly wrap cut watermelon in plastic wrap or store it in an airtight container.
- Original Quality: If the watermelon was already starting to spoil before it was cut, it will go bad even faster.
Safe Handling and Storage:
- Refrigerate Immediately: Store cut watermelon in the refrigerator within two hours of cutting.
- Proper Wrapping: Wrap cut pieces tightly in plastic wrap or store them in an airtight container.
- Optimal Temperature: Maintain a refrigerator temperature of 40°F (4°C) or below.
- Wash Before Cutting: Wash the entire watermelon thoroughly before cutting to minimize the transfer of bacteria from the rind to the flesh.
How Long Does Cut Watermelon Last?
Cut watermelon typically lasts for 3-5 days in the refrigerator if stored properly. Always use your senses (sight, smell, taste) as the ultimate guide. If you notice any signs of spoilage, discard the watermelon immediately.
