How Long Does Halved Cherry Tomatoes Last?

Halved cherry tomatoes decline faster than whole ones once cut, since exposing the juicy interior speeds both moisture loss and bacterial growth — a container of halved tomatoes typically holds up for only 2-3 days in the fridge before real decline, compared to the week or so whole cherry tomatoes can manage on the counter or in the fridge.

Mold, usually appearing first as a fuzzy spot near the cut surface or around the stem scar, is the clearest sign of spoilage, along with pooling juice that's turned cloudy rather than clear and a sour or fermented smell replacing the tomato's normal sweet, slightly acidic scent. A halved tomato that's gone visibly mushy and is leaking liquid throughout the container, rather than just at one soft spot, has moved well past the point of being salvageable by simply picking out the bad pieces.

Storing cherry tomatoes at room temperature rather than in the fridge, at least until they're cut, generally preserves better flavor and texture, since cold temperatures can make tomato flesh mealy — this applies to cherry tomatoes just as much as it does to a larger tomato, even though their smaller size sometimes leads people to treat them differently.

A cherry tomato halved with a serrated knife tends to bruise the cut edge less than one halved with a straight blade, which can make a small but real difference in how quickly that cut surface starts to break down in storage.
