When it comes to storing leftovers, there are a few key things to keep in mind in order to keep your food safe. First, be sure to store your leftovers in airtight containers. This will help to keep out any bacteria or other contaminants that could cause your food to spoil. Second, be sure to refrigerate your leftovers as soon as possible. The colder temperature will help to keep bacteria from growing. Finally, be sure to eat your leftovers within a few days. The longer they sit, the more likely they are to spoil. By following these simple tips, you can enjoy your leftovers without having to worry about foodborne illness.
