How many days can properly prepared and stored TCS food be kept?

Even with appropriate storage and preparation temperatures, bacteria can grow and multiply over time, so all TCS foods being held for longer than 24 hours must be clearly marked with the product name and either the date prepared, or the discard date to ensure it is not used past the appropriate time. Any food item stored in something other than its original container must be labeled with the item name and the date the original packaging was opened (or the discard date from the time of opening).
