Food safety numbers a new catering kitchen must hit
The holding, cooking, cooling and sanitizer numbers a new caterer's kitchen is measured against, plus allergen and transport rules.
What to take away
- Hold cold food at 41°F or below and hot food at 135°F or above.
- Cook poultry to 165°F, ground meat to 155°F, and whole fish and pork to 145°F.
- Cool in two stages135°F to 70°F within two hours, then 70°F to 41°F within four more.
- Chlorine sanitizer is measured at 50 to 100 ppm, and ready-to-eat food carries a seven-day date mark.
- Nine major allergens need labeling on packaged items, and supplier changes need tracking.
Holding temperatures for cold and hot food
Cold food holds at 41°F or below and hot food at 135°F or above. Those two lines apply in the walk-in, on the buffet and in the van. Put a working probe thermometer in the kitchen and on every vehicle.
Refrigerated ready-to-eat food held at 41°F or below carries a seven-day date mark. Label the container, move the oldest stock to the front, and discard what has passed its date. A stock control checklist keeps those dates visible on the shelf instead of in someone's memory.
Cooking and reheating targets
Each food has its own internal temperature and a hold time at that temperature. Cook to the number in the table, measure the thickest part, and write the reading in the log.
| Food | Internal temperature | Time rule |
|---|---|---|
| Poultry | 165°F | Held for 15 seconds |
| Ground meat | 155°F | Held for 17 seconds |
| Whole fish and pork | 145°F | Held for 15 seconds |
| Reheated food | 165°F | Reached within two hours |
Reheating has a clock of its own. Food that was cooked earlier and cooled must reach 165°F within two hours, so a banquet plan staggers the reheat by batch instead of loading every pan into the oven at once.
Cooling in two stages
Cooling has two deadlines, not one. Food drops from 135°F to 70°F within two hours, then from 70°F to 41°F within four more hours. Log the time at each of the three temperatures.
Large pots cool slowly, so split a batch into shallow pans before it goes into the cooler. Every cook who closes the kitchen should know both deadlines, and a training plan for a new hire can build them into the first week.
Sinks, sanitizer and handwashing
A hand sink needs hot and cold running water, soap and paper towels. Warewashing needs a three-compartment sink or a dish machine. Food Code 2022 Chapters 4 and 5 set the details for both.
Chlorine sanitizer is measured at 50 to 100 ppm. Test strips show the strength, so keep a roll at the sink and check each time a fresh batch is mixed. A reading outside the range goes in the log with the correction.
Allergen labels and supplier changes
FDA lists nine major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame. All nine need labeling on packaged items. Sesame joined the list on January 1, 2023.
A swapped supplier or brand can bring in an ingredient the recipe never had. Track supplier changes, keep each label or specification on file, and review the recipe card when a product changes. Sourcing choices are a food safety decision as much as a price one.
Food wrapped to a customer's order can fall outside the federal labeling duty. Ask every client about allergies before the menu is fixed, and write the answer on the event sheet.
Food in transit
Food in transit follows the same time and temperature rules as the kitchen. Every vehicle needs its own permit, a commissary agreement and potable water sized to the menu.
Read hot food against 135°F and cold food against 41°F at loading and again at delivery. Each state names its permit agency differently, so ask which rules cover a central kitchen, a mobile unit and a temporary event site.
Who must know the numbers
Food Code 2022 section 2-102.12 requires the person in charge to hold a certified food protection manager credential. That person has to explain holding, cooking and cooling to an inspector, and to the staff who do the work.
Model code versus local rule
State and local regulators use the FDA Food Code as a model for their own food safety rules. The figures above are the model's, not the text an inspector enforces.
States adopt the code with local amendments, so confirm the local wording before opening. The order of permits and plan review sits in the licensing and compliance steps that every new caterer works through.
A self-check before the first service
- Probe thermometer in the kitchen and on every vehicle
- Cold at 41°F or below and hot at 135°F or above, read and logged
- Cooling log with times at 135°F, 70°F and 41°F
- Sanitizer test strips at the sink, range 50 to 100 ppm
- Allergen labels and supplier documents on file
Run the list again after any change in recipe, supplier or venue.
Catering Compliance Checklist
- Map jurisdiction-specific requirements
- Classify operation accurately
- Maintain food-safety controls
- Manage allergens and labels
- Protect workers around equipment
- Apply youth-employment limits
- Keep inspection-ready
Common questions
Does the 135°F line apply to a chafing dish at the venue?
Food away from the kitchen follows the same time and temperature rules as food inside it. Read the chafing dish against 135°F the way you would read a hot-holding unit.
How do I know the sanitizer is strong enough?
Test it with strips against the 50 to 100 ppm chlorine range, and log the reading each time a fresh batch is mixed.
Is the FDA Food Code the rule I must follow?
Not directly. States adopt it with local amendments, so the text your inspector enforces may differ. Ask the local health department which edition and amendments apply.
Is sesame one of the allergens on a label?
Yes. Sesame joined the list of nine major allergens on January 1, 2023.
