Nutritional Consultation: Vegetables and Fruits
1.
Cooked white rice and vegetables sealed in a plastic bag can be stored at room temperature for about 2 hours without the risk of bacterial growth.
2.
Cooked white rice and vegetables in an open plastic bag should not be left at room temperature for more than 1 hour to prevent bacterial growth.
3.
It is better to keep cooked white rice and vegetables sealed in a plastic bag at room temperature rather than open.
Ideally, they should not be left out for more than 2 hours.
4.
Sealing cooked white rice and vegetables in a plastic bag and refrigerating them is the better option.
They can be stored in the refrigerator for up to 3 to 4 days.
If you take them out after 5 hours and do not reheat, it is not advisable to eat them due to potential bacterial growth.
5.
If you have leftover congee and store it in the refrigerator, it is safe to reheat it after 5 hours using hot water before consuming.
6.
Apples and bananas can be kept at room temperature for several days, typically around 3 to 7 days.
However, bananas ripen faster at room temperature, while apples last longer in the refrigerator.
It is generally better to refrigerate apples for extended freshness, while bananas are best kept at room temperature until they ripen.

Dr. Fan Chunmei reply Nutrition
Hello, it is recommended that cooked food be reheated to a central temperature of above 70°C (158°F) before consumption to avoid the danger zone (7-60°C or 45-140°F), which can promote bacterial growth and cause discomfort.
For food storage, it is advised to refrigerate at temperatures below 7°C (45°F).
Do not leave cooked food at room temperature for more than 2 hours; in summer, when room temperature exceeds 30°C (86°F), do not leave it out for more than 1 hour to prevent bacterial proliferation and toxin production.
Generally, bananas should be stored at room temperature, while apples can be kept in the refrigerator to maintain freshness.
The longer fruits are stored, the more their nutrients and flavors may diminish, so we recommend consuming purchased fruits within a week.
Wishing you health and happiness! Sincerely, Dietitian Fan Chun-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info
When it comes to food safety, particularly regarding the storage of cooked rice and vegetables, there are several important guidelines to follow to minimize the risk of bacterial growth and ensure the food remains safe to eat. Here’s a comprehensive overview based on your questions:
1. Storing Cooked Rice and Vegetables at Room Temperature: Cooked rice and vegetables should not be left at room temperature for more than two hours. This is because bacteria can multiply rapidly at temperatures between 40°F (4°C) and 140°F (60°C), a range known as the "danger zone." If the ambient temperature is above 90°F (32°C), this time is reduced to just one hour. Therefore, it is crucial to refrigerate cooked foods promptly to prevent bacterial growth.
2. Sealed vs. Unsealed Storage: Whether you store cooked rice and vegetables in a sealed plastic bag or an open one, the two-hour rule still applies. However, sealing the food can help reduce exposure to air and contaminants, which may help maintain quality and prevent drying out. Nonetheless, the critical factor is the time spent at room temperature rather than the sealing method.
3. Best Practices for Storage: In general, it is advisable to store cooked rice and vegetables in a sealed container or bag to minimize exposure to bacteria and air. If you must leave them out, aim to keep them at room temperature for no longer than two hours. If you are uncertain about the time, it is safer to refrigerate them sooner rather than later.
4. Refrigeration Methods: When it comes to refrigeration, storing cooked rice and vegetables in a sealed container is preferable. This helps prevent cross-contamination and keeps the food fresh longer. Cooked rice and vegetables can typically be stored in the refrigerator for about 3 to 4 days. If you take them out after 5 hours and do not reheat them, it is not advisable to eat them as they may have entered the danger zone for bacterial growth.
5. Reheating Leftover Congee: If you have leftover congee that has been stored in the refrigerator, it is safe to reheat it after 5 hours, provided it was refrigerated promptly after cooking. Ensure that it is heated thoroughly to at least 165°F (74°C) to kill any potential bacteria that may have developed during storage.
6. Storing Apples and Bananas: Apples can be stored at room temperature for several days, typically up to a week, depending on their ripeness. Bananas, on the other hand, should be kept at room temperature until they reach the desired ripeness; once ripe, they can be stored in the refrigerator to slow down further ripening. However, refrigeration may cause the skin to darken, but the fruit inside remains good to eat.
In summary, food safety is paramount when storing cooked foods. Always aim to refrigerate cooked rice and vegetables within two hours of cooking, use sealed containers to minimize contamination, and ensure thorough reheating before consumption. For fruits like apples and bananas, consider their ripeness and storage conditions to maintain their quality. Following these guidelines will help ensure that your food remains safe and nutritious.
