Can tomatoes still be eaten after being stored in the refrigerator for 20 days?

Generally speaking, whether tomatoes can be eaten after being stored in the refrigerator for 20 days depends on the storage method and signs of spoilage. Tomatoes that have been properly sealed and remain in good condition may still be edible, while those improperly stored or already spoiled should not be consumed. The details are as follows:

If the tomatoes were fresh and undamaged initially, tightly sealed in a plastic storage bag and refrigerated, and after 20 days show no mold, softening, or rotting—retaining firm flesh without unpleasant odor, with only slight wrinkling of the skin—this indicates no bacterial growth. After thorough washing, they can still be safely consumed.

However, if the tomatoes had wounds before refrigeration, were not sealed properly, or were exposed to fluctuating refrigerator temperatures, after 20 days they may develop moldy skin, mushy and leaking flesh, or emit sour or foul odors, indicating spoilage. Even if the spoiled portions are cut away, the remaining flesh may already be contaminated. Consuming such tomatoes may easily cause gastrointestinal discomfort and should therefore be avoided.

For everyday storage, select tomatoes without damage, store them separately in sealed containers to prevent odor transfer, and keep them away from the refrigerator's air vents. It is recommended to consume them within one week. For longer-term storage, consider cutting them into pieces and freezing. Always carefully inspect the appearance and smell before consumption, and discard immediately if any abnormalities are detected, to avoid health risks due to prolonged storage.
