ServSafe Manager · Safe Preparation and Cooking of Food · 7 min read
Minimum Internal Cooking Temperatures
- Identify the required minimum internal cooking temperatures and holding times for various TCS foods under the FDA Food Code.
- Establish active managerial control procedures for training staff, monitoring cooking lines, using food thermometers correctly, and executing corrective actions.
- Apply regulatory standards for specialized cooking processes, noncontinuous cooking, roasts, consumer advisories, and service to highly susceptible populations.
Active Managerial Control and Temperature Verification
Cooking food to required minimum internal temperatures is a critical control point within a food safety management system designed to reduce biological pathogens to safe levels. However, as a food service manager, you must recognize that reaching a minimum cooking temperature does not reliably destroy bacterial spores or toxins already present in food. To ensure consistent food safety on the line, the manager must establish standard operating procedures that define exactly how and when staff monitor and record cooking temperatures. Managers must also monitor cooking lines regularly to verify that line cooks follow proper time and temperature critical limits during prep and service.
A safe cooking process requires both adequate heating and accurate measurement; managers must train staff to verify the required temperature and holding time rather than rely on guesswork. Managers must train staff to check cooking temperatures with an accurate, cleaned, and sanitized food thermometer. Cooks should be trained never to rely on cooking time or visual appearance alone to determine food safety doneness. For an accurate reading, the probe must be placed in the thickest part of the food and away from bone. Furthermore, managers should train staff to check thick or irregularly shaped foods in multiple locations to verify that all parts reach the required temperature. Thermometer probes must be cleaned and sanitized between food items to prevent cross-contamination.
Active managerial control also requires establishing routines for documentation and corrective action. When monitoring reveals that food has not reached its target, managers must ensure staff do not serve undercooked food and instead continue cooking it until the required temperature and holding time are met, or discard it. Managers should keep cooking records required by their procedures or applicable state and local rules. Note that the FDA Food Code does not set a universal retention period for routine cooking logs, and state and local regulatory authorities may enforce different editions of the food code; managers must always verify specific local cooking temperature rules.
Common mistakes
- Assuming that cooking food to its minimum internal temperature destroys bacterial spores or toxins already present in the product.
- Using visual appearance, juices, or elapsed cooking time instead of a cleaned, sanitized thermometer inserted into multiple thick parts to confirm doneness.
- Applying the 145°F (63°C) immediate-service egg standard to eggs that are cooked and held hot on a buffet line, which require 155°F (68°C) for at least 17 seconds.
- Beginning a noncontinuous cooking (par-cooking) process without prior regulatory approval of written operating procedures, or heating the food for longer than 60 minutes during the initial cook.
Key points
- Cooking food to minimum internal temperatures is a critical control point that reduces biological pathogens to safe levels but does not destroy pre-existing spores or toxins.
- Whole or ground poultry, wild game, stuffing with animal proteins, and stuffed meats, seafood, or pastas must reach 165°F (74°C) instantaneously.
- Microwave-cooked TCS foods must reach 165°F (74°C) in all parts, be covered, be rotated or stirred, and stand covered for 2 minutes; most cooked and cooled TCS foods reheated for hot holding must reach 165°F (74°C) for 15 seconds within 2 hours, subject to the Food Code’s separate reheating rules.
- Ground meats, injected or mechanically tenderized meats, ground seafood, ratites, and raw shell eggs not prepared to order for immediate service require 155°F (68°C) for 17 seconds; specified seafood and meat cuts, and raw shell eggs broken and prepared to order for immediate service, require 145°F (63°C) for 15 seconds.
- Plant foods cooked for hot holding must reach 135°F (57°C), whereas plant foods served immediately have no minimum internal cooking temperature requirement.
- Roasts require 145°F (63°C) for 4 minutes or an applicable alternative continuous holding time, including 130°F (54°C) for 112 minutes; par-cooking requires prior regulatory approval of written procedures, initial heating of no more than 60 minutes, cooling under the Food Code’s time-temperature limits, frozen storage or cold holding at 41°F (5°C) or below, and full final cooking.
- Raw or undercooked animal foods covered by the Food Code’s consumer-advisory rule require a disclosure and reminder, with an exception for qualifying whole-muscle intact beef steaks; managers serving highly susceptible populations must not offer prohibited raw or undercooked animal foods or raw seed sprouts.
