Food Safety

  • Temperature danger zone is 41°F to 135°F (5°C to 57°C); hold cold foods at or below 41°F and hot foods at or above 135°F.

  • Two-stage cooling: 135°F to 70°F within 2 hours, then 70°F to 41°F within 4 more hours, for a 6-hour total maximum.

  • Reheating for hot holding must reach 165°F (74°C) within 2 hours; reheating is permitted only once for previously cooked food.

  • FATTOM = Food, Acidity, Time, Temperature, Oxygen, Moisture: the six conditions bacteria need to multiply; remove any one to inhibit growth.

  • Bacteria multiply fastest between 70°F and 125°F and can double roughly every 20 minutes under ideal conditions.

  • Handwashing requires at least 20 seconds of scrubbing with soap and warm running water, then drying with a disposable towel or air dryer.

  • Big Six pathogens requiring exclusion or restriction of food employees: Salmonella Typhi, Shigella, Shiga toxin-producing E. coli, Hepatitis A, Norovirus, and nontyphoidal Salmonella.

  • Biological hazards cause the majority of foodborne illness; viruses such as Norovirus and Hepatitis A are not destroyed by cooking and spread via hands and ready-to-eat food.

  • Cross-contamination controls: color-coded cutting boards, separate raw and ready-to-eat prep, and sanitizer concentrations of 50-100 ppm chlorine or 200-400 ppm quaternary ammonium.

Food Safety

  • A foodborne illness outbreak is two or more persons with the same illness from a common food; report suspected outbreaks to the local regulatory authority.

  • Active managerial control means the person in charge monitors critical control points such as cooking, cooling, and holding, and takes corrective action when limits are missed.

  • TCS foods (time/temperature control for safety) include meats, poultry, fish, eggs, dairy, cut melons, leafy greens, cooked rice, and sprouts.

  • Date marking: ready-to-eat TCS food held over 24 hours must be marked with a discard date no more than 7 days from preparation at 41°F or below, day 1 being the prep date.

  • Cooking minimums: poultry and stuffed foods 165°F; ground meat and eggs for hot holding 155°F; whole-muscle fish and pork 145°F for 15 seconds; vegetables for hot holding 135°F.

  • Proper cold-holding equipment keeps food at 41°F or below; check with a calibrated probe thermometer, not the unit's dial gauge.

  • Bare-hand contact with ready-to-eat food is prohibited; use utensils, deli tissue, or single-use gloves changed between tasks and after touching the face or waste.

  • A HACCP plan has seven principles: hazard analysis, determine CCPs, establish limits, monitor, corrective actions, verify, and record keeping.

Food Safety

  • Cross-connection control requires an air gap or approved backflow preventer; a hose submerged in a mop sink is a common violation.

  • Sanitizing solutions must contact food-contact surfaces for the labeled time, typically 30 seconds for chlorine and 60 seconds for quaternary ammonium.

  • Manual warewashing: wash at 110°F, rinse in clean water, sanitize, then air dry; do not towel dry.

  • Thermometers must be calibrated using the ice-point method at 32°F (0°C) or boiling-point method at 212°F (100°C).

  • Pest control: keep exterior doors self-closing and tight-fitting, screen windows, seal cracks, and store food at least 6 inches off the floor.

  • Integrated pest management prioritizes prevention and sanitation over routine pesticide application; only licensed applicators may apply restricted pesticides.

  • Employee health: exclude workers with vomiting, diarrhea, or jaundice; restrict workers with a lesion or a sore on the hand from ready-to-eat food contact.

  • Allergen control: the nine major allergens are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame; prevent cross-contact, not just cross-contamination.

Food Safety

  • Food defense differs from food safety: it targets intentional contamination, so control physical access to storage, receiving, and utility areas.

  • Approved suppliers must be inspected; receiving rejects frozen food with large ice crystals, discoloration, or temperatures above 41°F for cold TCS food.

  • Shellstock tags must be retained 90 days from the date the last shellfish is served or sold.

  • Cleaning removes visible soil with detergent; sanitizing reduces pathogens to safe levels on a clean surface; both steps are required in that order.

  • Facility design follows a forward flow: receiving, storage, preparation, cooking, holding, and service, to prevent cross-contamination.

  • Variance or specialized process approval is needed for curing, smoking for preservation, reduced-oxygen packaging, and sprouting seeds.

  • Imminent health hazard, such as a sewage backup or loss of potable water, requires stopping operations and notifying the regulatory authority.

  • Food handler training and documented standard operating procedures are core verification records for an active managerial control system.

Food Safety

  • FIFO rotation: use oldest stock first; label and date all stored food and keep raw meat below ready-to-eat food in the cooler.

  • Cooler storage order top to bottom: ready-to-eat food, whole fish, whole cuts of beef and pork, ground meat, then poultry.

  • Hot-holding equipment must maintain 135°F or above; if food drops below, reheat to 165°F within 2 hours or discard.

  • Time as a public health control allows holding TCS food without temperature control for up to 4 hours, then the food must be discarded.

  • Freezer storage keeps food at 0°F or below; frozen food must be thawed under refrigeration, under running water at 70°F or below, or as part of cooking.

  • The FDA Food Code is a model code adopted, often with amendments, by state and local jurisdictions; the local regulatory authority sets the enforceable requirement.

  • Employee handwashing frequency: before starting work, after using the restroom, after handling raw meat, after touching hair or face, and after handling garbage.

  • Chemical storage must be separated from food and food-contact surfaces and kept in labeled original or approved containers.

Food Safety

  • Flow of food steps: purchasing, receiving, storing, preparing, cooking, holding, cooling, reheating, and serving; each has a temperature and time control.

  • Ice used for food or beverages must be made from potable water and must never be used as a coolant for food or beverages.

  • Serving: use clean and sanitized utensils; hold plates by the edge; never touch the food-contact surface of utensils.

  • Off-site service and catering require transport equipment that maintains safe temperatures and a plan for holding and reheating.

  • Vending and mobile units need potable water, handwashing facilities, and temperature control documented for TCS items.

  • A consumer advisory is required for raw or undercooked animal foods offered for sale, such as raw oysters or rare burgers.

  • Record-keeping supports verification: temperature logs, sanitizer logs, receiving logs, and corrective action notes demonstrate active managerial control.

  • Food safety culture indicators include leadership commitment, ongoing training, accountability, and prompt reporting of hazards and illness.

Food Safety

  • Bacteria growth phases are lag, log, stationary, and death; the log phase is when population increases exponentially and is the target of temperature control.

  • Spore-formers such as Clostridium botulinum and Bacillus cereus survive normal cooking; cooling and reheating controls prevent toxin formation.

  • Clostridium perfringens is associated with cooled meats and gravies held in the temperature danger zone; rapid cooling prevents it.

  • Staphylococcus aureus is carried on skin and in nasal passages; it produces a heat-stable toxin, so cooking does not make the food safe.

  • Listeria monocytogenes grows at refrigeration temperatures and is a special risk for pregnant people, older adults, and immunocompromised people.

  • Norovirus is the leading cause of foodborne illness in the United States and spreads through the fecal-oral route and contaminated surfaces.

  • Parasites such as Anisakis in fish are controlled by freezing according to the FDA Food Code time and temperature schedule.

  • Chemical hazards include cleaning agents, sanitizers, and pesticides; physical hazards include glass, metal, bone, and jewelry.

  • An allergen cross-contact event requires cleaning and sanitizing equipment and utensils between allergen and non-allergen production.
