ServSafe temperatures: the complete chart

Time & Temperature is the heaviest domain on the exam, and almost every question in it comes down to one of the numbers below. Learn these and you have bought yourself a large slice of the marks. Everything here is drawn from the public FDA Food Code.

Cook to these minimum internal temperatures

TemperatureWhat it coversHold time
165°F (74°C)Poultry, stuffed food, reheated leftovers, food cooked in a microwave15 seconds
155°F (68°C)Ground meat, and eggs held for later service17 seconds
145°F (63°C)Fish and shellfish, pork, whole cuts of beef and veal, eggs for immediate service15 seconds
135°F (57°C)Plant food — vegetables, fruit, grains and legumes (for hot holding)15 seconds

The Food Code gives 17 seconds at 155°F; plenty of course materials round it to 15. Check your provider's materials, and never state a temperature lower than the one above.

Hold at these

RuleNumber
Hot holding135°F (57°C) or hotter
Cold holding41°F (5°C) or colder
The danger zoneBetween 41°F and 135°F — where bacteria grow fastest
Receiving cold TCS food41°F or colder; milk and shell eggs may arrive at 45°F or colder
Reheating for hot holding165°F for 15 seconds, within 2 hours

Cool on this curve

Stage one
135°F → 70°F within 2 hours
Stage two
70°F → 41°F within 4 more hours
Total
6 hours, in two stages

The first stage is the one people fail. A deep pan of hot stew cools far more slowly than anyone expects, which is why the approved methods are shallow pans, ice baths, ice paddles and dividing the batch.

Hours without temperature control

SituationLimit
Cold food held without temperature control6 hours, starting at 41°F or below, never above 70°F
Hot food held without temperature control4 hours, starting at 135°F or above
Both casesMark the food with the time it must be discarded, and throw it out at that time — not later

The three other numbers that come up

NumberWhere it applies
180°F (82°C)Final rinse in a heat-sanitising dish machine
171°F (77°C)Hot water sanitising in a three-compartment sink, 30 seconds of contact
100°F (38°C)Minimum water temperature at a handwashing sink

How to remember them without a mnemonic

  1. Start from the top and walk down. 165, 155, 145, 135 — four steps, each 10 degrees apart, from "most dangerous to cook wrong" (poultry) to "least" (vegetables).
  2. 41–135 is the danger zone, and both ends of it are also holding temperatures. Learn the pair as one fact.
  3. 180 belongs to the dish machine, not to food. Nothing you cook goes to 180 — that single sentence prevents the most common wrong answer in the whole domain.
  4. Two and four make six. Cooling is 2 hours to 70, then 4 hours to 41. Cold food without temperature control gets 6 hours; hot food gets 4.

Test yourself on the four numbers

A cook is reheating chilli for the hot bar. What internal temperature does it need?
  • 135°F (57°C)
  • 145°F (63°C)
  • 165°F (74°C) — correct
  • 180°F (82°C)

165°F for 15 seconds, within two hours. Reheating is the one place where a food that cooks at 135 goes up to 165, because it has already been through the danger zone once. FDA Food Code 3-403.11

Which of these is cooked to 155°F?
  • A whole pork loin
  • Ground beef patties — correct
  • Grilled salmon
  • Steamed broccoli

Ground meat. Grinding mixes surface bacteria through the whole portion, so ground meat needs a higher temperature than the whole cut it came from: 155°F rather than 145°F. FDA Food Code 3-401.11

Questions people ask

Do I need to memorise the Celsius figures too?

The exam is written in Fahrenheit, but the questions often show both (165°F / 74°C). Learn the Fahrenheit numbers and let the Celsius version jog your memory rather than replacing it.

Is 41°F or 40°F correct for cold holding?

41°F is the number in the FDA Food Code and on the exam. Some operations run their fridges colder as a safety margin, which is good practice, but the exam answer is 41°F.

Where do these numbers come from?

The public FDA Food Code — the same document the exam is built on. Each explanation in this trainer cites the chapter or section so you can verify it yourself.
