Temperature danger zone
The range from 41°F to 135°F (5°C to 57°C) in which bacteria multiply rapidly; TCS foods should not remain in this range longer than four hours cumulatively.
Two-stage cooling
Cool cooked food from 135°F to 70°F within two hours, then from 70°F to 41°F within an additional four hours, for a total of six hours.
Reheating for hot holding
Reheat previously cooked TCS food to 165°F for at least 15 seconds within two hours before placing it in hot holding.
Hot holding minimum
TCS foods held for service must remain at 135°F (57°C) or above; check temperature at least every four hours.
Cold holding maximum
TCS foods held cold must remain at 41°F (5°C) or below; monitor with a calibrated thermometer at least every four hours.
Time as public health control
Food may be held without temperature control for up to four hours if the start time is marked and the food is discarded after that period.
Poultry cooking temperature
Poultry, stuffed foods, and stuffed meats must be cooked to a minimum internal temperature of 165°F (74°C) for at least 15 seconds.
Ground meat cooking temperature
Ground beef, pork, and other ground meats must be cooked to at least 155°F (68°C) for 17 seconds.
Whole muscle meat temperature
Whole cuts of beef, pork, veal, and lamb must reach 145°F (63°C) for 15 seconds, followed by a three-minute rest.
Thermometer calibration
Calibrate thermometers using ice-point (32°F) or boiling-point (212°F) methods; adjust to the known temperature before use.
Norovirus characteristics
Highly contagious virus spread by infected handlers, ready-to-eat foods, and contaminated water; causes vomiting and diarrhea; low infectious dose.
Hepatitis A transmission
Fecal-oral route; often linked to shellfish and RTE foods handled by an infected worker; incubation about 28 days; preventable by vaccination.
Shiga toxin-producing E. coli
Pathogen linked to ground beef and leafy greens; causes severe bloody diarrhea; infectious dose can be very low; cook ground beef thoroughly.
Listeria monocytogenes
Bacterium that grows at refrigeration temperatures; linked to deli meats, soft cheeses, and smoked seafood; dangerous for pregnant women and immunocompromised people.
Staphylococcus aureus
Bacterium that produces a heat-stable toxin in foods handled by infected workers; linked to RTE foods and dairy; toxin survives cooking.
Clostridium perfringens
Spore-forming bacterium linked to cooled and reheated meats and gravies; grows in the temperature danger zone; causes diarrhea.
Bacillus cereus
Spore-forming bacterium with two syndromes: emetic (rice, pasta) and diarrheal (meats, stews); spores survive normal cooking.
Big Six pathogens
Salmonella Typhi, nontyphoidal Salmonella, Shigella spp., STEC, hepatitis A, and norovirus; these require exclusion of infected workers.
Handwashing duration
Scrub hands, backs, between fingers, and under nails with soap for at least 20 seconds, then rinse and dry with a disposable towel.
Hand antiseptic use
Hand antiseptics may be used only after proper handwashing and never as a substitute for washing hands.
Glove change rules
Change single-use gloves when torn, soiled, between tasks, after handling raw animal foods, and before handling ready-to-eat foods.
Worker illness reporting
Food handlers must report diarrhea, vomiting, jaundice, fever, or infected wounds to the person in charge immediately.
Fingernail requirements
Fingernails must be short, clean, and unpolished; artificial nails are prohibited when handling exposed food.
Cross-contamination prevention
Separate raw animal foods from ready-to-eat foods; use color-coded cutting boards; clean and sanitize between uses.
Sanitizer concentration
Chlorine sanitizer at 50–100 ppm; quaternary ammonium per label; iodine at 12.5–25 ppm; verify with test strips.
Sanitizer contact time
Food-contact surfaces must remain wet with sanitizer for at least 30 seconds before air-drying.
Cleaning versus sanitizing
Cleaning removes soil and food residue; sanitizing reduces pathogens on surfaces to safe levels after cleaning.
Handwashing sink separation
Handwashing sinks must be used only for handwashing and must be separate from food prep, dishwashing, and utility sinks.
Pest control principles
Deny pests entry, food, water, and harborage; use integrated pest management and licensed pest control operators.
Receiving temperatures
Cold TCS foods must arrive at 41°F or below; frozen foods must be solidly frozen; shell eggs at 45°F or below.
Date marking rule
Ready-to-eat TCS foods held over 24 hours must be date-marked and discarded after seven days at 41°F or below.
HACCP seven principles
Hazard analysis, CCP identification, critical limits, monitoring, corrective actions, verification, and recordkeeping.
Active managerial control
A preventive approach where the person in charge actively controls risk factors such as holding, cooking, and hygiene in daily operations.
Critical control point
A step where control can prevent, eliminate, or reduce a food safety hazard to an acceptable level; must have measurable critical limits.
Corrective action documentation
When a critical limit is not met, the operator must take corrective action and record what was done to restore control.
FDA Food Code role
A model regulation that state and local jurisdictions adopt or adapt; it is not federal law and does not itself regulate establishments.
Imminent health hazard
A significant threat such as sewage backup, no potable water, or pest infestation that requires immediate correction or closure.
Person in charge duties
The PIC must demonstrate food safety knowledge, monitor operations, take corrective action, and ensure employee training and reporting.
