Storing rice correctly is essential to maintaining its freshness and safety for consumption. Many people choose to store leftover cooked rice in the refrigerator to extend its shelf life and minimise food waste. However, understanding the optimal duration for safely storing rice can help prevent foodborne illnesses and ensure the rice remains tasty and nutritious. Maximum duration for safely storing cooked rice Kanikka Malhotra, consultant dietician and certified diabetes educator, tells indianexpress.com, “Cooked rice can be safely stored in the refrigerator for four to six days under optimal conditions. However, various factors can influence this timeframe.” She continues, “Rice should be cooled quickly before refrigeration. If left at room temperature for too long (ideally no more than two hours), it can enter the ‘temperature danger zone,’ where bacteria can grow. Using shallow containers to store rice helps it cool faster and reduces the risk of bacterial growth.” The type of container used for storage matters, Malhotra mentions. Airtight containers limit exposure to air and moisture, which can help preserve the rice longer. Conversely, storing rice in a large, deep container may keep it warm longer, increasing the risk of spoilage. The refrigerator should also maintain a temperature of 40°F (4°C) or below. If the refrigerator is not cold enough, the rice may spoil faster. The initial quality of the rice and how it was cooked can also affect its longevity. Rice that has been cooked properly and stored correctly will last longer than rice that has been mishandled. “For individuals at higher risk of foodborne illnesses (such as the elderly, pregnant women, or those with weakened immune systems), it is advisable to consume cooked rice within two to four days for added safety,” asserts Malhotra. Specific signs that indicate cooked rice has gone bad or is no longer safe to eat Malhotra stresses, “Cooked rice can spoil even within the recommended storage period, and several signs indicate it is no longer safe to eat. An unpleasant or sour smell is a primary indicator of spoilage, suggesting bacterial growth.” Additionally, if the rice has developed a slimy texture, this indicates moisture retention and potential fermentation, making it unsafe to consume. Discolouration or the presence of mould, such as green, blue, or black spots, are clear signs that the rice should be discarded immediately. Even if cooked rice appears normal, Malhotra states, if it has been improperly stored or left at room temperature for too long, it can harbour harmful bacteria like Bacillus cereus, which can lead to food poisoning. Best practices for cooling and storing cooked rice To maximise the freshness of cooked rice and minimise the risk of bacterial growth, follow these best practices for cooling and storing: *After cooking, allow the rice to cool to room temperature within 1-2 hours. To expedite cooling, divide large batches into smaller portions and spread them out in shallow containers. This method increases surface area and helps the rice cool faster, reducing the time it spends in the ‘danger zone,’ where bacteria can thrive. *Once the rice has cooled, transfer it to the refrigerator. It's crucial not to place hot rice directly into the fridge, as this can raise the temperature of surrounding foods and promote bacterial growth. Aim to refrigerate the rice within four hours of cooking. *Store the cooled rice in airtight containers or resealable plastic bags. This prevents moisture accumulation and keeps out bacteria, while also protecting the rice from absorbing odours from other foods in the fridge. *Divide the rice into individual portions before storing. This practice not only makes reheating more convenient but also reduces the need to reheat the entire batch multiple times, which can lead to increased bacterial growth. *Always label containers with the date of storage. Cooked rice should be consumed within 4-6 days when refrigerated, and if you don’t plan to eat it within that time frame, consider freezing it for longer storage, where it can last for 1-2 months.
