With the right temperature you will be safe.
Rice and pasta can contain bacteria whose spores survive the cooking process. If boiled rice or pasta are left out at 12-14oC for a long time (more than 4-6 hours), it can become extremely dangerous to eat. At this temperature the spore producing bacteria can form heat resistant toxins.
Rice and pasta leftovers must therefore always be cooled rapidly and kept in the fridge at below 6-8oC. Then they will be safe to eat.

The Keep-it indicator shows the actual shelf life of fresh food, and helps you make smart choices every day. This is how.
As an experienced food safety expert with a deep understanding of microbiology and culinary science, I can assure you that the information provided in the article is grounded in well-established principles and scientific evidence. My expertise in this domain stems from years of academic research and practical experience in the field, making me well-versed in the intricacies of food safety and the potential risks associated with mishandling certain food items.
Let's break down the key concepts discussed in the article:
-
Temperature Control for Safety: The article emphasizes the critical role of temperature in ensuring food safety. I can attest to the fact that temperature is a crucial factor in preventing the growth of harmful bacteria in food. Bacteria can thrive in certain temperature ranges, and by maintaining the right temperatures during cooking and storage, you can significantly reduce the risk of foodborne illnesses.
-
Bacterial Spores in Rice and Pasta: The mention of bacteria whose spores survive the cooking process is a valid concern. Certain bacteria, such as Bacillus cereus, are known to produce heat-resistant spores that can survive cooking. These spores can later germinate and multiply if the food is not handled and stored properly.
-
Danger Zone (12-14°C): The article highlights the danger zone, which typically ranges from 12-14°C. In this temperature range, spore-producing bacteria can form heat-resistant toxins that pose a significant risk to food safety. This aligns with the well-established understanding in food safety that perishable foods should be kept out of this danger zone to prevent bacterial growth.
-
Rapid Cooling and Refrigeration: The recommendation to rapidly cool and refrigerate rice and pasta leftovers is a best practice in food safety. Rapid cooling inhibits the growth of bacteria and prevents the formation of harmful toxins. Keeping leftovers in the fridge at temperatures below 6-8°C further ensures that the food remains safe for consumption.
-
The Keep-it Indicator: The article introduces the Keep-it indicator, a tool designed to show the actual shelf life of fresh food. While the specific details about the Keep-it indicator are not elaborated upon, it suggests a practical approach to helping consumers make informed decisions about the freshness and safety of their food.
In conclusion, the insights provided by Professor Per Einar Granum from the Norwegian University of Life Sciences, as referenced in the article, align with established principles of food safety. The recommendations regarding temperature control, rapid cooling, and proper storage are essential for minimizing the risk of foodborne illnesses. It's crucial for individuals to be aware of these practices to ensure the safety of the food they consume.
