While it’s generally recommended to consume food within a few hours of preparation, there are certain factors that can impact the safety of eating cooked food that’s been left out for a prolonged period. In this article, we’ll explore the ins and outs of this topic and help you make an informed decision about whether or not to indulge in that forgotten meal. So, buckle up and let’s dive in!

Quick Answer:
No, it is not safe to eat cooked food that has been left out for 12 hours. According to the USDA, cooked food that has been left at room temperature for more than two hours should be discarded. This is because bacteria can grow rapidly on cooked food, especially if it is not stored properly. Eating food that has been left out for 12 hours can lead to foodborne illness, which can cause symptoms such as nausea, vomiting, diarrhea, and fever. It is important to store cooked food properly in the refrigerator or freezer to prevent bacterial growth and to ensure food safety.

Factors that affect food safety

Time

How long is too long?

When it comes to food safety, time is a critical factor. Per the USDA, cooked food that has been left out at room temperature for more than two hours should be discarded. This is because bacteria grow rapidly at temperatures between 40°F and 140°F, which is the “danger zone.” The longer cooked food is left out, the more time bacteria have to multiply, increasing the risk of foodborne illness.

Danger zone

The “danger zone” refers to the temperature range at which bacteria can multiply rapidly. This range is between 40°F and 140°F. It’s crucial to keep cooked food out of this range for as short a time as possible to minimize the risk of foodborne illness.

Cooling food safely

To cool cooked food safely, it’s essential to follow the two-hour rule. Cool the food to room temperature, then refrigerate it. Never let cooked food sit at room temperature for more than two hours, even if it’s refrigerated later. If you need to cool large quantities of food, do it in smaller portions. Divide the food into shallow containers, then refrigerate or freeze them promptly.

Storing cooked food

Storing cooked food safely is also critical to prevent bacterial growth. Cooked food should be stored in shallow containers, loosely covered, and refrigerated at a temperature of 40°F or below. The USDA recommends using food thermometers to ensure that the refrigerator’s temperature is below 40°F.

It’s important to note that some foods, such as potatoes and tomatoes, can produce a toxin even at refrigerator temperatures, so they should not be stored with other foods. Always wash hands, utensils, and work surfaces thoroughly after handling these foods.

Temperature

Hot holding temperature

What is the safe temperature range?

Cooked food that is left out at room temperature for more than two hours should not be consumed. However, there is a safe temperature range for hot holding, which means keeping cooked food at a specific temperature to prevent bacterial growth. The safe temperature range for hot holding is between 135°F (57°C) and 140°F (60°C).

How to maintain the safe temperature range

To maintain the safe temperature range for hot holding, it is important to use proper equipment and techniques. Here are some tips:

  • Use a food thermometer to check the temperature of the cooked food.
  • Keep the cooked food in a steam table or warming tray with a lid.
  • Set the temperature of the steam table or warming tray to 140°F (60°C).
  • Check the temperature of the cooked food every hour and reheat if necessary.
  • Do not let the cooked food sit at room temperature for more than two hours.

Cooler storage temperature

The safe temperature range for cooler storage is between 32°F (0°C) and 40°F (4°C). This means that cooked food should be stored in a cooler or refrigerator at a temperature between these two ranges to prevent bacterial growth.

To maintain the safe temperature range for cooler storage, it is important to use proper equipment and techniques. Here are some tips:

  • Store the cooked food in airtight containers or wrap it tightly in plastic wrap.
  • Store the cooked food in the cooler or refrigerator as soon as possible.
  • Do not store cooked food at room temperature for more than two hours.
  • Check the temperature of the cooked food every hour and discard it if it has been stored outside the safe temperature range.
