HACCP Principles — 10 Food Manager Exam Practice Questions

HACCP is the foundational science-based food safety system. The seven principles (FDA, USDA, NACMCF): (1) Conduct a Hazard Analysis — identify biological, chemical, and physical hazards in the operation and at each process step; (2) Determine Critical Control Points (CCPs) — points where control can be applied to prevent, eliminate, or reduce hazards to acceptable levels (typically cooking, cooling, hot holding); (3) Establish Critical Limits — measurable parameters at each CCP that must be met (e.g., chicken to 165°F internal); (4) Establish Monitoring Procedures — who, what, when, how to monitor each CCP; (5) Establish Corrective Actions — what to do when monitoring shows a CCP is not under control; (6) Establish Verification Procedures — activities other than monitoring that determine the HACCP plan is working (calibration, audits, testing); (7) Establish Record-Keeping and Documentation. HACCP plans are operation-specific; a plan that works for one restaurant may not work for another. Managers should lead HACCP plan development with team input. Documents to maintain: hazard analysis worksheets, CCP decision logs, monitoring records, corrective action records, verification records, training records. State and local regulators may require HACCP for high-risk operations (sushi, seafood, vacuum-packaging, modified atmosphere packaging).

TCS foods (formerly called Potentially Hazardous Foods/PHF) require strict time and temperature controls because their characteristics support pathogen growth or toxin formation. Characteristics that make foods TCS: (1) High water activity (Aw > 0.85); (2) Neutral or slightly acidic pH (4.6-7.5); (3) Protein-rich. Specific TCS foods per FDA Food Code: animal-based foods (meat, poultry, fish, shellfish, eggs, dairy); cooked plant-based foods (rice, beans, vegetables, pasta — once cooked, the matrix supports growth); cut leafy greens; cut tomatoes; cut melons; raw seed sprouts; garlic-in-oil mixtures (anaerobic, supports Clostridium botulinum); soy-protein products (tofu, soy milk); untreated garlic-in-oil; certain plant foods that have been heat-treated. Non-TCS foods: low Aw (dry foods, jam), low pH (most pickles, mayonnaise), or with effective preservation. Why important: Temperature Danger Zone is 41°F to 135°F (5°C to 57°C); TCS foods cannot be in this zone more than 4 hours total (or 6 hours per FDA Food Code if temperature monitored). Cold holding ≤41°F; hot holding ≥135°F. Time as a Public Health Control (TPHC) — using time alone instead of temperature — requires written procedures, marking, and 4 or 6 hour maximums.

FDA Food Code minimum internal cooking temperatures (food/seconds at temperature): (1) 165°F for 15 seconds: poultry (chicken, turkey, duck, goose); stuffed meats, poultry, pasta, fish; stuffing containing TCS food; food reheated for hot-holding; raw meat in microwave (covered, rotated, 2 min rest); (2) 155°F for 17 seconds: ground meat (beef, pork); mechanically tenderized or injected meat; ground or comminuted fish; ratites (ostrich); eggs to be hot-held; (3) 145°F for 15 seconds: seafood (fish, shellfish, crustaceans); pork, beef, lamb steaks/chops/roasts (intact, non-comminuted); commercially raised game; eggs for immediate service; (4) 145°F for 4 minutes (or other equivalent time-temperature combinations): roasts of beef and pork (longer time, lower temp acceptable); (5) 135°F: commercially processed, ready-to-eat foods being hot-held; fruits, vegetables, grains, legumes for hot-holding. Cooking temperatures destroy pathogens. Use calibrated thermometers; check temperature in the thickest part. Microwave cooking requires special handling — covered, rotated/stirred, 2 minute rest after cooking, then check temperature in multiple places.

Two-stage cooling per FDA Food Code: (1) From 135°F to 70°F: within 2 hours; (2) From 70°F to 41°F (or below): within additional 4 hours; (3) Total cooling time: 6 hours maximum from 135°F to 41°F. If the first stage (135°F to 70°F) takes more than 2 hours, the food must be discarded — it cannot be salvaged by faster cooling in the second stage. Why critical: temperature danger zone (41°F-135°F) supports rapid pathogen growth; cooling too slowly allows growth and toxin formation; pathogens like Clostridium perfringens and Bacillus cereus can produce heat-stable toxins that survive subsequent reheating. Effective cooling methods: (1) Shallow pans (food <2 inches deep) on top racks of cooler; (2) Ice baths with frequent stirring; (3) Ice paddles in liquid foods; (4) Blast chillers (rapid cooling units, can cool large quantities quickly); (5) Adding ice as an ingredient (e.g., to soup, then water is added); (6) Smaller portions in shallow containers. Don't: put hot food directly into cooler in deep containers; stack containers blocking airflow; rely on refrigeration alone to cool large hot batches. Monitor cooling with temperature checks — at 2 hours (should be ≤70°F) and at 6 hours (should be ≤41°F). Record temperatures.

FDA Food Code requires the Person in Charge (PIC) to manage employee illness. Reportable illnesses (employees must report; managers must notify regulators if confirmed): The 'Big Six' pathogens: (1) Salmonella Typhi; (2) Salmonella spp. (non-typhi); (3) Shigella spp.; (4) Shiga toxin-producing E. coli (STEC), including O157:H7; (5) Hepatitis A virus; (6) Norovirus. Symptoms requiring exclusion (cannot work at all): (1) Vomiting; (2) Diarrhea; (3) Jaundice (yellow skin/eyes); (4) Sore throat with fever (in establishments serving high-risk populations like daycares, nursing homes, hospitals); (5) Diagnosis of any Big Six pathogen. Restriction (cannot work with exposed food, utensils, or equipment but may work in other capacities) for: certain conditions and recovery periods. Infected open lesions: must be covered with impermeable bandage and glove (for hands) or otherwise excluded. Documentation: employees should sign written agreement understanding reporting obligations; managers maintain illness logs. Returning to work: requires being symptom-free, often 24+ hours after symptoms resolved; some pathogens require medical clearance or stool testing. Sick employees in food service is one of the leading causes of foodborne illness outbreaks. Norovirus, the most common cause, spreads easily through sick workers.

Person in Charge (PIC) requirements per FDA Food Code: (1) Always present during operating hours — a designated person responsible for food safety; (2) Demonstrate knowledge of foodborne disease prevention, application of HACCP principles, and Food Code requirements (typically demonstrated through certification); (3) Most jurisdictions require Certified Food Protection Manager (CFPM) certification — ANSI-accredited programs include ServSafe Manager, Prometric, NRFSP, ATF (Above Training and Food). Certification involves: (1) Coursework (online or classroom); (2) Proctored exam — typically 80+ questions, 75% passing; (3) Valid 5 years; (4) Renewal required. CFPM exam content: foundations of food safety, hazards, time/temp control, personal hygiene, cross-contamination, cleaning/sanitizing, regulatory authority, HACCP. PIC duties: (1) Train staff on food safety; (2) Monitor food safety practices throughout the operation; (3) Respond to issues and complaints; (4) Cooperate with regulatory inspections; (5) Manage employee illness and exclusions; (6) Ensure HACCP plan compliance if applicable; (7) Maintain documentation. Local regulations may add requirements. A facility without an on-site PIC during operating hours can be cited or shut down. PIC is responsible legally and operationally for food safety in their facility.

Receiving is a critical control point — first opportunity to ensure incoming food meets safety standards. Receiving procedures: (1) APPROVED SOURCES — verify suppliers are licensed, inspected, in good standing; for high-risk items (raw oysters, certain juices), specific source documentation may be required; (2) DELIVERY VEHICLE — inspect for cleanliness, working refrigeration, no chemical contamination, no pests; (3) TEMPERATURES — check incoming TCS food temperatures using calibrated thermometer: refrigerated TCS ≤41°F; frozen items should be frozen solid (any thawing or refreezing is a red flag — large ice crystals indicate temperature abuse); hot TCS ≥135°F; (4) PACKAGING — intact, no damage, no leaks, no holes, no signs of tampering, no swollen or rusted cans; ensure proper labels and dates; (5) PRODUCT CONDITION — color, odor, texture appropriate; no signs of spoilage, freezer burn, off-odors; (6) SHELLFISH — shellstock tags must be present and retained for 90 days from container empty date; (7) DOCUMENTATION — invoices, temperature logs, rejection records; (8) PROMPT STORAGE — refrigerated and frozen foods stored within 15-30 minutes of receipt. Rejection guidelines: temperature out of range, damaged packaging, signs of spoilage, missing required labels/tags, unknown source, signs of contamination, pest evidence. Document rejections with reason, date, item, supplier. Train all receivers; designate trained personnel for receiving.

Facility design directly affects food safety capability. Key elements: (1) SURFACES — floors, walls, ceilings: smooth, durable, non-absorbent, easily cleanable; floor-wall junctions coved (rounded); avoid wood floors in wet areas; (2) HAND-WASHING STATIONS — required in food prep, warewashing, restroom areas; equipped with hot/cold running water, soap, paper towels or air dryers, waste container; accessible (not blocked, not used for other purposes); (3) SINKS — separate dedicated sinks: hand-washing (cannot be used for food prep or warewashing), food prep (clean food preparation), warewashing (3-compartment for wash/rinse/sanitize), mop/utility (cleaning); food cannot be prepared in hand-washing or warewashing sinks; (4) PLUMBING — sized for demand; backflow prevention (air gaps, vacuum breakers, RPZ valves) to prevent cross-connection between potable water and waste; drainage that prevents sewage backup; (5) REFRIGERATION — adequate capacity, thermometers in each unit, capable of maintaining ≤41°F throughout; separate raw and ready-to-eat storage with raw below RTE; (6) DRY STORAGE — at least 6 inches off floor; temperature/humidity control as needed; pest exclusion; (7) PEST EXCLUSION — sealed openings, screens on windows, door sweeps, no harborage areas; (8) LIGHTING — adequate intensity (50 foot-candles at food prep, 20 at hand-washing, 10 in walk-ins); shielded bulbs to prevent contamination from breakage; (9) VENTILATION — sufficient to remove heat, moisture, smoke; hood systems over cooking equipment.

Regulatory inspections protect public health. The Person in Charge (PIC) must cooperate fully. Inspection rights and responsibilities: (1) The regulator has authority to enter the facility during normal operating hours (refusing entry can be a violation); (2) The PIC must allow access to all food preparation, storage, and service areas; (3) The regulator can ask questions, observe operations, take temperatures, test samples; (4) Records may be requested (temperature logs, employee health, CFPM certificates, HACCP plans, pest control records, etc.). During the inspection: (1) Accompany the inspector throughout; (2) Answer questions honestly and completely — do not speculate, but provide accurate information; (3) Take notes on observations and instructions; (4) Address easily-fixed violations immediately if possible (this can reduce penalties and shows good faith); (5) Do not argue with the inspector — disagreements can be addressed through appeals; (6) Sign the inspection report — signature acknowledges receipt of the report, not necessarily agreement with findings; (7) Receive a copy of the report. After the inspection: (1) Correct cited violations within required timeframes; (2) Maintain documentation of corrections; (3) Re-train staff on related issues; (4) Investigate root causes; (5) Prepare for re-inspection if required. Imminent health hazards: regulator may order closure on the spot for critical violations (sewage backup, water outage, fire damage, infestation, no hot water). Follow-up inspections verify corrections. Repeated violations face escalating penalties.

FDA Food Code violation hierarchy (newer terminology used by FDA): (1) PRIORITY ITEMS — directly contribute to the elimination, prevention, or reduction of foodborne illness or injury (formerly 'critical'). Examples: cooking temperatures, cooling rates, hot/cold holding temperatures, employee health and handwashing, source of food, cross-contamination prevention, allergen handling, water source, sewage. Must be corrected typically within 72 hours or sooner. (2) PRIORITY FOUNDATION ITEMS — items whose absence/improper application could lead to priority item violations (formerly partially 'critical'). Examples: written procedures, equipment requirements, training. Must be corrected within longer timeframes. (3) CORE ITEMS — general sanitation, maintenance, and equipment care (formerly 'non-critical'). Examples: storage practices, general cleanliness, facility maintenance. Must be corrected typically within 90 days. Most jurisdictions follow this hierarchy or similar. Some still use 'critical' and 'non-critical' or 'major' and 'minor.' Score-based systems: facilities receive scores based on the number and severity of violations. Failure to correct priority items can lead to: closure orders; expedited re-inspection; legal action; suspension or revocation of permits; civil and criminal penalties. Public information: in many jurisdictions, inspection reports are public records; some require posted grades or scores in the facility.
