Chicken
If you’re wondering when to get rid of any other leftovers like chicken or beef, it will depend on what you did with it on the day of cooking.
Poultry that has been kept in the fridge can be safely stored for three to four days if the temperature is 4C or below.
Cooked chicken can also be kept in a freezer for three to four months as long as it has not been exposed to room temperature conditions for more than two hours while cooling down.
Beef
Chilled beef can be consumed for two to three days after being cooked as long as it is wrapped in cling film, foil, or tightly covered in a container.
For frozen storage, wrap red meat in freezer paper, heavy foil, or place in a freezer bag, and use it within two to three months.
