Melons

Watermelon, cantaloupe, and honeydew each have whole vs cut storage windows. Cut melon is the perishable form — refrigerate it promptly. Past a cut-melon fridge window, discard it. Fridge = safety for cut fruit; freezer = quality if you freeze at all.
Watermelon cut fridge 3–5 days · whole 2–3 weeks cut spoils faster Whole keeps longer; cut pieces need the fridge promptly. Cantaloupe cut fridge 3–5 days · whole 2–3 weeks cut spoils faster Netted rind can trap dirt — wash before cutting; refrigerate cut melon. Honeydew cut fridge 3–5 days · whole 2–3 weeks cut spoils faster Smooth rind still needs a wash before cutting; refrigerate cut melon.

Fridge vs freezer

Whole melons can often sit cool at room temperature or in the fridge for longer quality storage (FoodKeeper). Once cut, melon flesh is moist and perishable — follow the cut-state refrigerator window on each food page and discard past it. Freezing melon is a quality choice (texture turns soft on thaw); it is not a way to rescue melon that already sat out too long.

How to tell melon is spoiled

Sour or fermented smell, slimy cut surfaces, mold on the flesh or rind cut edge, and large soft collapsed areas mean discard it. Cantaloupe’s netted rind can hide dirt in the grooves — wash before cutting so the knife does not drag contaminants into the flesh (FDA produce guidance).

Storage tips

Safety notes

FDA and CDC treat cut melon as a produce item that needs refrigeration and clean handling. Outbreaks have historically involved cantaloupe rinds contaminating flesh at cutting — washing first is the control you can do at home. Not medical advice.
