ServSafe Time as a Public Health Control: How to Safely Hold Hot and Cold Food Without Temperature Control
Can you hold hot or cold food without temperature control? Yes—but only when specific food safety requirements are followed.
Restaurants, caterers, delis, cafeterias, buffets, and other food service operations sometimes need to temporarily hold TCS foods (Time/Temperature Control for Safety foods) without refrigeration or hot-holding equipment.
ServSafe addresses this situation through Time as a Public Health Control (TPHC).
Instead of temperature being the primary control, time becomes the control. Food must be monitored, properly identified, and discarded within the required time limit.
What Is Time as a Public Health Control?
Time as a Public Health Control is a food safety procedure that allows certain TCS foods to be removed from temperature control for a limited amount of time.
Normally, TCS food must be maintained at safe temperatures:
Cold holding: 41°F or below
Hot holding: 135°F or above
When food is outside these temperature limits, bacteria can multiply rapidly.
TPHC provides a controlled method for using time instead of temperature—but it is not permission to leave food sitting out all day.
ServSafe Hot Food Holding Without Temperature Control
Under the ServSafe TPHC approach, hot TCS food can generally be held without temperature control for up to 4 hours.
The food must:
Start at 135°F or higher
Be identified with the time it was removed from temperature control
Be monitored according to the establishment's approved procedure
Be discarded after the four-hour limit
Example of Hot Food TPHC
A restaurant removes cooked chicken from a hot-holding unit at 12:00 PM for a special event.
The food is labeled with the time it was removed.
The four-hour limit expires at 4:00 PM.
Any remaining food must be discarded.
The food should not simply be placed back into hot holding and served later.
ServSafe Cold Food Holding Without Temperature Control
Cold TCS foods may also be held without temperature control under an approved TPHC procedure.
Using the ServSafe approach, cold food may generally be held for up to 6 hours when specific conditions are met.
The food must:
Start at 41°F or below
Be properly identified with the time it was removed from refrigeration
Not exceed 70°F
Be monitored during the holding period
Be discarded when the allowable time expires
If the food reaches 70°F before the six-hour limit, it must be discarded.
Example of Cold Food TPHC
A deli removes prepared tuna salad from refrigeration at 10:00 AM.
The food starts at 41°F or below and is properly labeled with the removal time.
The food may be held under the approved TPHC procedure for the permitted period.
If the food reaches 70°F before the six-hour limit, it must be discarded immediately.
Why Time and Temperature Matter
Bacteria can multiply quickly when TCS food is exposed to temperatures that allow bacterial growth.
This is why food safety managers need to understand:
Time + Temperature = Food Safety
If temperature control is removed, time must be carefully controlled.
Employees should never estimate how long food has been sitting out.
Labeling Food Is Critical
One of the simplest ways to prevent mistakes is to clearly label food when it is removed from temperature control.
A label should identify the appropriate removal time so employees know exactly when the discard deadline occurs.
For example:
REMOVED FROM TEMPERATURE CONTROL: 12:00 PM
DISCARD: 4:00 PM
Clear labeling helps prevent employees from guessing.
Can You Put TPHC Food Back Into the Refrigerator?
This is an area where food employees frequently make mistakes.
Food being held under a TPHC procedure must be handled according to the specific procedure being used and applicable food code requirements.
Do not assume that putting food back into refrigeration makes it safe.
Employees should follow the establishment's written food safety procedure and local health department requirements.
Written TPHC Procedures
Food establishments using Time as a Public Health Control should have a written procedure describing how the process will be conducted.
The procedure should address:
Which foods are covered
Starting temperatures
Maximum allowable time
Required labeling
Monitoring
Discard procedures
Employee responsibilities
Food managers should make sure employees understand the procedure before allowing them to use time as a public health control.
Common Food Safety Mistakes
Leaving Food Out Without Tracking Time
"It's only been out for a little while" is not a food safety procedure.
Guessing Temperatures
Employees should use a calibrated food thermometer when temperature measurement is required.
Forgetting the Starting Temperature
TPHC procedures have specific starting-temperature requirements.
Missing the Discard Time
If employees don't know when the food was removed from temperature control, they cannot accurately determine the allowable holding period.
Assuming Food Is Safe Because It Looks Normal
You cannot determine whether food is safe by looking at it, smelling it, or tasting it.
ServSafe Training for Restaurant Managers
Understanding Time as a Public Health Control is just one part of proper food safety management.
A certified food protection manager should understand how to control:
Hot holding
Cold holding
Cooking temperatures
Cooling
Reheating
TCS foods
Cross-contamination
Personal hygiene
Cleaning and sanitizing
Food allergens
Receiving and storage
Time and temperature controls
Proper training gives food service employees the knowledge they need to make safer decisions every day.
