Can tomatoes that have been stored in the refrigerator for half a month still be eaten?
Generally speaking, whether tomatoes stored in the refrigerator for half a month can still be eaten depends on their storage condition and whether they have spoiled. They are edible if properly refrigerated and not spoiled, but should not be consumed if improperly stored or already deteriorated. The details are as follows:

If the tomatoes were intact before being placed in the refrigerator and sealed in a plastic bag for cold storage, and after half a month show no damage or mold, with full flesh, no strange odor, and no soft, watery texture—only slightly wrinkled skin—they are likely not spoiled and can be safely consumed after thorough washing.
However, if the tomatoes were not sealed during refrigeration or had existing wounds, after half a month they may develop moldy skin, soft and mushy flesh, emit sour or foul odors, or even leak juice. This indicates bacterial growth, and consuming them may cause gastrointestinal discomfort. In such cases, they should not be eaten.
For daily storage, select undamaged tomatoes, wrap each individually in a sealed plastic bag to prevent compression or collision, and store in the refrigerator's chill compartment. It is best to consume them within one week. For longer storage, wash and cut them into pieces before freezing. Always carefully inspect appearance and smell before consumption, and discard immediately if any abnormalities are found to ensure food safety.
