Comprehensive ServSafe and Food Safety Management Study Guide

Pathogen Transmission, Hand Behavior Hazards, and Managerial Responsibilities

• Asymptomatic and Post-Symptomatic Pathogen Transmission:
  • Individuals can transmit pathogens before manifesting clinical symptoms. For example, Hepatitis A can be spread for weeks prior to symptom onset.
  • Norovirus can continue to spread for days after clinical symptoms have resolved.
  • Certain illnesses allow individuals to infect others for days, weeks, or even months following symptom disappearance.
  • Carriers: Individuals who harbor pathogens within their bodies and transmit them to others without presenting any illness themselves.
• Unsafe Actions That Contaminate Food:
  • Scratching the scalp or running fingers through hair.
  • Sneezing or coughing into hands.
  • Wiping hands on aprons or clothing.
  • Rubbing an ear lobe or ear canal.
  • Touching or wiping the nose.
  • Touching an infected wound, pimple, or skin lesion.
  • Spitting within the food operation.
• Managerial Responsibilities for Personal Hygiene:
  • Develop comprehensive, written personal hygiene policies.
  • Periodically revise personal hygiene policies to align with updated food safety laws and scientific advancements.
  • Train all food handlers on hygiene policies upon hire and deliver regular retraining.
  • Continuously supervise food safety practices during all operational hours.
  • Model correct personal hygiene behaviors at all times so staff observe proper practices in action.

Handwashing, Hand Care, and Wound Management Protocols

• Dedicated Handwashing Facilities:

  • Hands must never be washed in sinks designated for food preparation, dishwashing, or wastewater disposal.
• Five-Step Handwashing Procedure:
  • The entire handwashing process must take at least $20\text{ seconds}$.
  • Step 1: Wet hands and arms with warm running water.
  • Step 2: Apply sufficient soap to build a thorough lather, following manufacturer guidelines.
  • Step 3: Scrub hands and arms vigorously for $10\text{ to }15\text{ seconds}$. Clean under fingernails, around fingertips, and between fingers.
  • Step 4: Rinse hands and arms thoroughly under warm running water.
  • Step 5: Dry hands and arms completely using a single-use paper towel or a warm/high-velocity air hand dryer.
  • Recontamination Prevention: Use a single-use paper towel to turn off faucet handles and open restroom doors when exiting.
• Corrective Actions for Hand Contamination:
  • Discard any food touched by unclean hands or contaminated bare hands.
  • Clean and sanitize any equipment or utensils exposed to unclean hands.
  • Retrain and coach non-compliant food handlers immediately.

  • Must be allowed to dry completely before touching food or equipment.
  • Must comply with standards set by the Food and Drug Administration (FDA) and the Code of Federal Regulations (CFR).
• Fingernail Care and Polish Restrictions:
  • Fingernails must be kept short, clean, and neatly filed to prevent pathogens and physical contaminants from harboring beneath them.
  • Nail polish and false fingernails are prohibited unless the food handler wears single-use gloves at all times.
• Infected Wounds, Cuts, and Boils:
  • Infected wounds contain pus and harmful bacteria; staff must report open or draining wounds immediately.
  • Wounds on the hand, finger, or wrist: Cover with an impermeable cover (such as a liquid-tight bandage or finger cot) and place a single-use glove over the cover.
  • Wounds on the arm: Cover completely with an impermeable cover that prevents fluid leakage.
  • Wounds on other body parts: Cover completely with a dry, durable, tight-fitting bandage.

Single-Use Gloves and Bare-Hand Contact Rules

• Single-Use Glove Standards:

Preventing Cross-Contamination and Time-Temperature Abuse

• Steps in the Flow of Food: Purchasing $\rightarrow$ Receiving $\rightarrow$ Storing $\rightarrow$ Preparation $\rightarrow$ Cooking $\rightarrow$ Holding $\rightarrow$ Cooling $\rightarrow$ Reheating $\rightarrow$ Service.
• Methods to Prevent Cross-Contamination:
  • Use separate equipment for raw and ready-to-eat (RTE) foods.
  • Utilize color-coded equipment (e.g., Red = raw meat, Yellow = raw poultry, Green = fresh produce).
  • Wash, rinse, and sanitize all work surfaces, equipment, and utensils before and after each task.
  • Prep raw meats, poultry, seafood, and RTE foods at different times or at separate workstations (prep RTE foods before raw items).
  • Separate raw animal foods from unwashed produce and RTE foods during storage, prep, holding, and display.
  • Purchase food items that require minimal handling (pre-cut or pre-washed items).
• Temperature Danger Zone (TDZ):
  • TDZ Range: $41^\circ\text{F}\text{ to }135^\circ\text{F}\,(5^\circ\text{C}\text{ to }57^\circ\text{C})$.
  • Rapid Growth Zone: Pathogens grow most rapidly between $70^\circ\text{F}\text{ and }125^\circ\text{F}\,(21^\circ\text{C}\text{ and }52^\circ\text{C})$.
  • Maximum cumulative time food may remain in the TDZ before being discarded: $4\text{ hours}$.
• Preventing Time-Temperature Abuse:
  • Establish clear operational policies detailing which foods to check, how often, and by whom.
  • Provide calibrated thermometers and timers to staff.
  • Record temperatures and log recording times on forms posted near equipment.
  • Limit the volume of TCS food removed from cold storage during preparation.
  • Implement immediate corrective actions if time-temperature standards are violated.

Thermometer Types, Calibration, and Standard Usage

• Types of Food Service Thermometers:
  • Bimetallic Stem Thermometer:
    • Measures temperatures from $0^\circ\text{F}\text{ to }220^\circ\text{F}\,(-18^\circ\text{C}\text{ to }104^\circ\text{C})$.
    • Features an indicator head scaled in minimum $2^\circ$ increments, a calibration nut, and a metal stem containing a dimple.
    • Temperature-sensing area extends from the tip of the stem to the dimple; must be inserted into food up to the dimple (suitable for thick/large foods, not thin foods).
  • Thermocouples and Thermistors:
    • Measure temperatures via a metal probe with digital displays.
    • Sensing element is located strictly at the tip of the probe (suitable for both thick and thin foods).
    • Penetration probe: Sharp tip for internal temperature of thin foods (fish fillets, ground beef patties).
    • Immersion probe: Measures liquid temperatures (soups, sauces, frying oil).
    • Surface probe: Measures flat cooking surface temperatures (griddles).
    • Air probe: Measures ambient air temperature inside coolers and ovens.
  • Infrared Thermometers:
    • Measure surface temperatures of food and equipment without contact.
    • Cannot measure internal food temperatures or ambient air temperatures.
    • Do not take readings through glass, stainless steel, or aluminum.
  • Specialized Monitoring Devices:
    • Maximum Registering Thermometer: Records the highest temperature reached during use (used for high-temperature dishwasher final rinse cycles).
    • Time-Temperature Indicator (TTI): Package tag attached by suppliers that changes color irreversibly if time-temperature abuse occurs in transit/storage.
    • Temperature Recording Devices: Installed inside delivery trucks to continuously monitor and log cargo ambient air temperatures.
• Thermometer Maintenance and Accuracy Standards:
  • Wash, rinse, sanitize (using food-contact surface safe sanitizer), and air-dry thermometers before and after each use.
  • Food temperature thermometers must be accurate to $\pm 2^\circ\text{F}\text{ or }\pm 1^\circ\text{C}$.
  • Ambient air storage thermometers must be accurate to $\pm 3^\circ\text{F}\text{ or }\pm 1.5^\circ\text{C}$.
• Calibration Methods:
  • Ice-Point Method ($32^\circ\text{F}\,[0^\circ\text{C}]$): Fill a container with crushed ice and tap water; submerge probe sensing area for $30\text{ seconds}$ without touching container sides/bottom; adjust calibration nut/digital setting to read $32^\circ\text{F}\,(0^\circ\text{C})$.
  • Boiling-Point Method ($212^\circ\text{F}\,[100^\circ\text{C}]$ depending on elevation): Submerge probe in boiling water and adjust to boiling temperature.
  • Calibration Timing: Calibrate before each shift, before receiving deliveries, after being dropped/bumped, or after extreme temperature exposure.
• Measurement Guidelines: Insert probe into the thickest part of the food (center). Take a second reading in a different spot. Wait $15\text{ seconds}$ after insertion for bimetallic readings to stabilize. Glass thermometers must be enclosed in a shatterproof casing.

    3. Whole cuts of beef and pork
    4. Ground meat and ground fish
    5. Whole and ground poultry (Bottom shelf)
  • Exceptions: Commercial pre-packaged sealed raw meats can be stored above RTE food in freezers. Thawing raw meat in a cooler must always be stored below RTE food.
• Prohibited Storage Areas: Locker rooms, dressing rooms, restrooms, garbage rooms, mechanical rooms, under unshielded sewer/water lines, or under stairwells.
• Segregating Compromised Food: Store damaged, expired, or recalled items away from safe food and label with "Do Not Use / Do Not Discard".

Food Preparation, Thawing Methods, and Specialized Processes

• General Safe Prep Practices:
  • Clean and sanitize workstations, cutting boards, and utensils before prep.
  • Remove only small batches of TCS food from refrigeration at a time.
  • Additives: Use only legally approved additives; never use more than permitted; never use additives or sulfites to alter appearance. Do not add sulfites to produce eaten raw or serve produce treated with sulfites prior to receipt.
  • Honest Presentation: Food must be presented accurately without false lighting, colored wraps, or deceptive descriptions.
  • Reconditioning: Restoring food to safety (e.g., reheating hot TCS food held in the TDZ for less than $2\text{ hours}$). Throw out food touched by sick employees or contaminated by bodily fluids.
• Four Acceptable Thawing Methods:
  1. In a cooler at $41^\circ\text{F}\,(5^\circ\text{C})$ or lower.
  2. In a microwave oven, only if cooked immediately afterward in conventional cooking equipment.
  3. Submerged under drinkable running water at $70^\circ\text{F}\,(21^\circ\text{C})$ or lower with sufficient force to wash off loose particles. Water temp must keep food $\le 41^\circ\text{F}\,(5^\circ\text{C})$ for no more than $4\text{ hours}$ total (thaw time + prep/cooling time).
  4. As part of the cooking process (e.g., frozen burger patty directly onto grill).
  • Reduced Oxygen Packaged (ROP) Fish: Must be removed from ROP packaging before thawing under refrigeration, or immediately before/after thawing under running water.
• Specific Food Item Preparation Rules:
  • Produce:
    • Refrigerate sliced melons, cut tomatoes, and cut leafy greens at $41^\circ\text{F}\,(5^\circ\text{C})$ or lower.
    • Wash produce thoroughly under running water slightly warmer than the produce prior to cutting/cooking.
    • Remove outer leaves on greens (lettuce, spinach) and pull completely apart to rinse.
    • Do not wash multiple batches or different produce items in standing water/ice slurries.
    • Never serve raw seed sprouts to high-risk populations.
  • Eggs:
    • Pooled eggs: Cook immediately after cracking or store at $41^\circ\text{F}\,(5^\circ\text{C})$ or lower. Sanitize containers between batches.
    • Pasteurized eggs: Use in undercooked/raw dishes (hollandaise, Caesar dressing, tiramisu, mousse) and when serving high-risk populations (unless dish is fully cooked, such as a cake or omelet).
  • Salads with TCS Ingredients (Tuna, Chicken, Egg, Pasta, Potato): Leftovers can be used only if prepped, cooked, cooled, and held at $41^\circ\text{F}\,(5^\circ\text{C})$ or lower for no more than $7\text{ days}$.
  • Ice: Must be made from potable water. Never use ice as an ingredient if it was used to keep food cold. Store scoops outside ice machines in clean locations; do not scoop with glass or bare hands.
• Variances and HACCP Requirements:
  • A Variance is a document issued by the local regulatory authority allowing a requirement to be waived or changed.
  • Specialized processes requiring a Variance (+ HACCP Plan):
    1. Packaging fresh juice on-site for later sale (unless labeled with warning).
    2. Smoking food as a method of preservation (not for flavor).
    3. Curing food.
    4. Using food additives or vinegar to alter/preserve food so it does not require time/temp control.
    5. Sprouting seeds or beans.
    6. Offering live shellfish from a display tank.

Cooling, Reheating, and Holding Controls

• Two-Step Cooling Process (Total $6\text{ hours}$ maximum):
  • Step 1: Cool hot TCS food from $135^\circ\text{F}\text{ to }70^\circ\text{F}\,(57^\circ\text{C}\text{ to }21^\circ\text{C})$ within $2\text{ hours}$.
  • Corrective Action: If food does not reach $70^\circ\text{F}$ in $2\text{ hours}$, it must be reheated to $165^\circ\text{F}\,(74^\circ\text{C})$ or discarded.
  • Step 2: Cool food from $70^\circ\text{F}\text{ to }41^\circ\text{F}\,(21^\circ\text{C}\text{ to }5^\circ\text{C})$ or lower in the remaining time (up to $4\text{ additional hours}$).
  • Bonus Time: If Step 1 takes less than $2\text{ hours}$, the remaining time transfers to Step 2 (total cooling time cannot exceed $6\text{ hours}$).
• Factors and Methods for Fast Cooling:
  • Factors: Thick/dense foods cool slower than thin liquids. Large batches cool slower than small batches. Stainless steel containers disperse heat faster than plastic.
  • Methods: Divide into shallow pans or smaller containers; place in an ice-water bath; stir frequently; stir with an ice paddle; add ice/water as an ingredient; use a blast chiller. Loosely cover or leave uncovered if protected from overhead drip.
• Reheating Requirements:
  • Immediate service: Food cooked/cooled properly can be reheated to any temp for immediate service.
  • Hot holding TCS food: Must be reheated to an internal temperature of $165^\circ\text{F}\,(74^\circ\text{C})$ for $15\text{ seconds}$ within $2\text{ hours}$ (all methods, including microwave).
  • Commercially processed RTE food: Reheat to at least $135^\circ\text{F}\,(57^\circ\text{C})$.
• Holding Guidelines:
  • Hot holding: $135^\circ\text{F}\,(57^\circ\text{C})$ or higher. Cold holding: $41^\circ\text{F}\,(5^\circ\text{C})$ or lower.
  • Check internal temps with a thermometer at least every $4\text{ hours}$ (check every $2\text{ hours}$ to allow time for corrective reheating). Cover food; use sneeze guards. Never use hot-holding equipment to reheat food.
• Holding Without Temperature Control:
  • Requires written procedures maintained on-site and pre-approval. Prohibited for raw shell eggs in high-risk facilities.
  • Cold Food (Up to $6\text{ hours}$):
    • Held at $\le 41^\circ\text{F}$ prior to removal.
    • Label with remove time and discard time ($6\text{ hours}$ later).
    • Temp must not exceed $70^\circ\text{F}\,(21^\circ\text{C})$ during service.
    • Alternative: Discard within $4\text{ hours}$ if held at $\le 41^\circ\text{F}$ initially (can reach any temp).
    • Cut produce/opened canned TCS: Can start at $\le 70^\circ\text{F}$, discard within $4\text{ hours}$ if temp stays $\le 70^\circ\text{F}$.
  • Hot Food (Up to $4\text{ hours}$):
    • Held at $\ge 135^\circ\text{F}$ prior to removal.
    • Label with remove time and discard time ($4\text{ hours}$ later). Discard within $4\text{ hours}$.

Service Standards and Food Protection

• Kitchen and Service Staff Handling Standards:
  • Kitchen: Use gloves, tongs, spatulas, or deli sheets for RTE food. Clean/sanitize utensils every $4\text{ hours}$ during continuous use. Store in-use utensils in food with handle above rim, on clean surfaces, or in water at $\ge 135^\circ\text{F}\,(57^\circ\text{C})$.
  • Service: Avoid bare-hand contact with RTE food. Hold plates by bottom/edge; glasses by middle, bottom, or stem; flatware by handle (store handles up). Never stack glasses; use trays/racks. Use ice scoops/tongs.
• Preset Tableware: Wrap or cover preset tableware. If left uncovered, remove extra settings when guests are seated; clean/sanitize unremoved settings after guests leave.
• Reserving Food Restrictions:
  • Never reserve returned food, plate garnishes, uneaten bread/rolls, or uncovered/opened condiments.
  • Permissible Re-served items: Unopened, prepackaged, un-damaged items (condiment packets, wrapped crackers) and unopened condiment bottles.
• Self-Service Displays (Buffets and Salad Bars):
  • Protect with sneeze guards or display cases. Label food items (e.g., dressing ladles). Stock correct dispensing utensils.
  • Prevent plate reuse (post signs, assign staff monitoring). Keep hot food $\ge 135^\circ\text{F}$, cold food $\le 41^\circ\text{F}$.
  • Raw meat/seafood prohibited EXCEPT: Sushi/raw shellfish, raw shell-on shrimp/lobsters, Mongolian BBQ raw ready-to-cook portions.
• Off-Site Catering and Vending Machines:
  • Catering: Use insulated food-grade containers; clean delivery vehicles; label food with use-by date/time and reheating/service instructions. Ensure catering sites have safe potable water and proper garbage disposal.
  • Vending Machines: Check shelf life daily (toss prepped RTE food within $7\text{ days}$). Hold cold TCS food $\le 41^\circ\text{F}$, hot TCS food $\ge 135^\circ\text{F}$. Must have automatic cutoff controls if temp enters danger zone. Dispense TCS food in original containers; wash and wrap fruit with edible peels.

Food Safety Management Systems and Active Managerial Control

• Pillars of a Strong Food Safety Culture:
  • Leadership commitment from top-down.
  • Prioritizing food safety in decision-making.
  • Standardizing procedures and terminology across the operation.
  • Collaborating with suppliers and regulatory authorities.
  • Providing proper tools and resources.
  • Managerial modeling of expected behaviors.
  • Setting clear expectations and holding staff accountable.
  • Recognizing and rewarding compliance.
  • Conducting initial/ongoing training and explaining the "whys" behind rules.
• Three Core Elements of a Food Safety Management System:
  1. Establishment of written food safety policies and procedures.
  2. Employee training on policies.
  3. Operational monitoring of compliance.
• Five Common Risk Factors for Foodborne Illness:
  1. Purchasing food from unsafe sources.
  2. Failing to cook food correctly.
  3. Holding food at incorrect temperatures.
  4. Using contaminated equipment.
  5. Practicing poor personal hygiene.
• Active Managerial Control (AMC) Steps:
  1. Identify and document potential risks and hazards.
  2. Monitor critical operational activities.
  3. Take immediate corrective actions.
  4. Exercise management oversight (verify compliance).
  5. Train and retrain employees.
  6. Reevaluate the system periodically.
• FDA Public Health Interventions:
  1. Demonstration of knowledge (manager certification).
  2. Staff health controls (illness reporting protocols).
  3. Controlling hands as a vehicle of contamination (no bare-hand contact with RTE food).
  4. Time and temperature parameters for controlling pathogens.
  5. Consumer advisories.
• Seven HACCP Principles (in sequential order):
  1. Conduct a hazard analysis.
  2. Determine critical control points (CCPs).
  3. Establish critical limits.
  4. Establish monitoring procedures.
  5. Identify corrective actions.
  6. Verify that the system works.
  7. Establish procedures for recordkeeping and documentation.
• Self-Inspections: Conducted in-house or by third parties, mirroring regulatory authority forms. Inspect facility, utilities, grounds, equipment, employee hygiene, food handling steps, cleaning/sanitizing, and documentation.

Facility Design, Equipment Standards, and Pest Control

• Plan Review Benefits: Submitting plans prior to construction/remodeling ensures regulatory compliance, optimal food flow, approved equipment selection, saving time and money. Valid operating permit required.
• Facility Material Standards:
  • Floors, walls, ceilings: Smooth, durable, easy to clean, maintained (repair holes, replace broken tiles).
  • Coving: Curved, sealed edge between floor and wall that eliminates sharp corners and protects against moisture/pests.
• Equipment Sanitation Standards and Installation:
  • Look for NSF, UL EPH, or ETL Sanitation marks (certified under ANAB/ANSI accredited programs).
  • Floor-mounted equipment: Mounted on legs at least $6\text{ inches}\,(15\text{ cm})$ high OR sealed to a masonry base.
  • Tabletop equipment: Mounted on legs at least $4\text{ inches}\,(10\text{ cm})$ high OR sealed to the countertop.
• Handwashing Station Requirements:
  • Required in restrooms/adjacent areas, food prep, service, and dishwashing areas. Used only for handwashing.
  • Mandatory items: Hot/cold running potable water delivered through a mixing valve at $\ge 85^\circ\text{F}\,(29^\circ\text{C})$; liquid, bar, or powder soap; disposable paper towels or warm/high-velocity air dryer; garbage receptacle (if paper towels used); clear handwashing sign.
• Potable Water Sources and Plumbing Hazards:
  • Potable water: Water safe to drink (public mains, tested private sources, closed portable containers, water transport vehicles).
  • Cross-Connection: Physical link between potable water and dirty water.
  • Backflow / Backsiphonage: Reverse flow of contaminants into potable water caused by pressure changes or vacuums.
  • Prevention: Air gap (only 100% reliable method; separates outlet from dirty water; sinks need 2 air gaps: faucet-to-rim and drain-to-floor drain). Vacuum breakers, double check valves, reduced pressure zone backflow preventers.
  • Grease traps: Prevent pipe blockages; installed by licensed plumbers; cleaned regularly.
• Lighting, Ventilation, and Garbage Management:
  • Lighting: Intensity measured in foot-candles or lux (brightest in prep areas). Bulbs must be shatterproof or enclosed.
  • Ventilation: Removes heat, steam, smoke, fumes; prevents grease/condensation buildup.
  • Garbage: Remove promptly. Clean containers inside/out away from food prep. Receptacles must be leak-proof, waterproof, pest-proof, covered when not in use. Covered receptacle required in women's restrooms. Outdoor pads: Smooth, nonabsorbent (concrete/asphalt), tight lids, drain plugs in place.
• Imminent Health Hazards:
  • Threats requiring immediate correction or operation closure (power failure, fire, flooding, sewage backup, water contamination).
  • Stop service, notify regulatory authority, discard compromised food, correct problem, obtain clearance to reopen.
• Integrated Pest Management (IPM) - Three Basic Rules:
  1. Deny pests access (screens, door sweeps, self-closing doors, air curtains/fly fans, seal pipe cracks).
  2. Deny pests food, water, and shelter (prompt garbage disposal, clean spills immediately, store food $\ge 6\text{ inches}$ off floor away from walls, FIFO, store recyclables in pest-proof containers).
  3. Work with a licensed Pest Control Operator (PCO).
  • Infestation signs: Live/dead pests, feces, nests, gnaw damage. Pesticides must be applied exclusively by certified applicators.

Cleaning, Sanitizing, and Chemical Safety Procedures

• Definitions:
  • Cleaning: Removes visible food residue and dirt from surfaces.
  • Sanitizing: Reduces pathogens on surfaces to safe levels.
  • Disinfecting: Destroys/inactivates bacteria, fungi, viruses (not spores). Leaves residue unsafe for food surfaces; used for bodily fluid cleanup.
• Sanitizing Methods:
  • Heat Sanitizing: Soak in hot water at $\ge 171^\circ\text{F}\,(77^\circ\text{C})$ for at least $30\text{ seconds}$, or use high-temperature dishwasher.
  • Chemical Sanitizing: Chlorine, Iodine, Quaternary Ammonium Compounds (Quats).
• Chemical Sanitizer Effectiveness Parameters:
  • Chlorine: Water temp $\ge 100^\circ\text{F}\,(38^\circ\text{C})$, pH $\le 10$, concentration $50\text{--}99\text{ PPM}$, contact time $\ge 7\text{ seconds}$; OR water temp $\ge 75^\circ\text{F}\,(24^\circ\text{C})$, pH $\le 8$, concentration $50\text{--}99\text{ PPM}$, contact time $\ge 7\text{ seconds}$.
  • Quats: Water temp $75^\circ\text{F}\,(24^\circ\text{C})$, hardness $\le 500\text{ PPM}$ (or per manufacturer), concentration per manufacturer, contact time $\ge 30\text{ seconds}$.
  • Iodine: Water temp $68^\circ\text{F}\,(20^\circ\text{C})$, pH $\le 5$ (or per manufacturer), concentration $12.5\text{--}25\text{ PPM}$, contact time $\ge 30\text{ seconds}$.
• Five Steps to Clean and Sanitize Surfaces:
  1. Scrape or remove food bits from surface.
  2. Wash surface with approved cleaner.
  3. Rinse surface with clean water.
  4. Sanitize surface with approved sanitizer solution at correct concentration.
  5. Air-dry surface.
• When Food-Contact Surfaces Must Be Cleaned and Sanitized:
  • After each use.
  • Before working with a different type of food (e.g., switching from raw meat to fish, or cutting melons then leafy greens).
  • After any interruption during a task.
  • After $4\text{ hours}$ of continuous use.
• Stationary Equipment Cleaning (e.g., Slicers): Unplug $\rightarrow$ Remove removable parts (wash, rinse, sanitize in dishwasher/sink) $\rightarrow$ Scrape/wash/rinse/sanitize fixed surfaces $\rightarrow$ Air-dry $\rightarrow$ Reassemble. Clean-in-place equipment (soft-serve machines) must be cleaned daily.
• Dishwashing Operational Protocols:
  • High-Temp Machines: Final sanitizing rinse $\ge 180^\circ\text{F}\,(82^\circ\text{C})$ (or $\ge 165^\circ\text{F}\,[74^\circ\text{C}]$ for stationary rack single temperature). Measure surface temps using maximum registering thermometers or heat-sensitive tape.
  • Chemical Sanitizing Machines: Wash/sanitize at lower temps per manufacturer directions.
  • Three-Compartment Sink Setup:
    
    • Sink 1: Detergent and water $\ge 110^\circ\text{F}\,(43^\circ\text{C})$.
    • Sink 2: Clean rinse water.
    • Sink 3: Water and chemical sanitizer at correct concentration (or hot water $\ge 171^\circ\text{F}$). Provide a clock with a second hand.
  • Three-Compartment Sink Steps: Scrape/soak $\rightarrow$ Wash in Sink 1 $\rightarrow$ Rinse in Sink 2 $\rightarrow$ Sanitize in Sink 3 $\rightarrow$ Air-dry upside down. Never towel dry; never rinse after sanitizing.
• Storage of Cleaned Items: At least $6\text{ inches}\,(15\text{ cm})$ off the floor. Cups/glasses upside down; flatware handles up.
• Wiping Cloths:
  • Wet cloths: Stored in fresh sanitizer solution between uses. Keep raw meat cloths separate.
  • Dry cloths: Used for wiping food spills from service plates; kept dry and visually clean.
• Vomit and Diarrhea Cleanup: Operations must have written, trained cleanup procedures to minimize Norovirus contamination.
• Chemical Safety and Master Cleaning Schedules:
  • Safety Data Sheets (SDS) must be accessible to all employees.
  • Store chemicals in original containers away from food/utensils (or in labeled working containers with common name).
  • Master Cleaning Schedule Elements: What should be cleaned, Who should clean it, When it should be cleaned, and How it should be cleaned.
