Is using a thermos bowl for kids lunch safe them to eat if the food is out 5 hours?

It is generally not recommended to keep perishable foods in a thermos bowl for more than 2-3 hours, especially at room temperature. Bacteria can grow rapidly in the temperature danger zone, which is between 40°F and 140°F. Leaving food out for an extended period of time can increase the risk of foodborne illnesses.

While a thermos bowl can help maintain the temperature of the food, it is important to consider other factors such as the type of food, initial temperature of the food, and the ambient temperature. Some foods are more susceptible to bacterial growth than others and should be consumed within a shorter period of time.

To ensure the safety of your child's lunch, it is best to follow these guidelines:

- Prepare the lunch with perishable foods that are properly cooked and chilled.

- Pack the lunch in a well-insulated lunch bag or container.

- Use a thermos bowl for foods that need to be kept hot, but consume them within 2-3 hours.

- Avoid leaving the lunch unrefrigerated for extended periods of time, especially in warm temperatures.

- Reheat any perishable food to an internal temperature of 165°F before consuming if it has been out for an extended period of time.

By following these guidelines, you can help reduce the risk of foodborne illnesses and ensure that your child's lunch remains safe to eat.
