ServSafe Comprehensive Food Safety Notes

Handwashing & Personal Hygiene

  • Hand-washing sink must always have:
    • Continuous running potable water
    • Soap (liquid or foam)
    • Single-use paper towels OR an air dryer (many kitchens now prohibit air dryers because they can aerosolize contaminants)
    • Trash receptacle for used towels
  • Hand‐washing occasions (non-exhaustive list used in class scenarios): before starting work; after restroom, smoking, eating, touching hair/face/body, handling raw TCS food, handling money, taking out trash, using chemicals, clearing tables, sneezing/coughing, etc.
  • Jewelry rule for hands/arms: ONLY a plain wedding band is allowed; no bracelets, watches, stones, medical bands, etc.

Equipment & Thermometers

  • Bimetallic-stem thermometer
    • Calibrate at the start of each shift, after dropping/bumping, after extreme temp change & after long storage – NOT literally before/after every single use.
    • Wait minimum 15 s15\text{ s} for a stable reading.
    • Accuracy requirements (ServSafe):
    – Food-probe devices: ±2∘F\pm 2^{\circ}F (±1∘C\pm 1^{\circ}C)
    – Air thermometers (refrigerator / oven): ±3∘F\pm 3^{\circ}F (±1.5∘C\pm 1.5^{\circ}C)
  • Air & product thermometers must be cleaned/sanitized and used in the thickest part of food; take at least 2 locations.

Temperature Principles

  • Temperature Danger Zone (TDZ): 41∘F – 135∘F41^{\circ}F \text{ – } 135^{\circ}F (5∘C – 57∘C5^{\circ}C \text{ – } 57^{\circ}C)
    • Rapid-growth “sweet spot”: 70∘F–125∘F70^{\circ}F – 125^{\circ}F (21∘C–52∘C21^{\circ}C – 52^{\circ}C)
  • Cumulative time in TDZ before food must be discarded: 4 h (unless special cold-holding exception below).
  • Two-stage cooling rule:
    • Stage 1 – cool from 135∘F135^{\circ}F to 70∘F70^{\circ}F within 2 h2\text{ h}
    • Stage 2 – cool from 70∘F70^{\circ}F to 41∘F41^{\circ}F within next 4 h4\text{ h}
    • Total cool time ≤ 6 h6\text{ h}
    • If stage 1 not met, reheat to 165∘F165^{\circ}F and start over OR discard.

Flow of Food Overview

  • Definition: Path food takes from receiving dock → storage → prep → cooking → holding → cooling → reheating → service → consumer’s mouth.
  • Hazards at every step: cross-contamination & time/temperature abuse.

Purchasing & Receiving

  • Buy only from approved suppliers (inspected; compliant with state & federal law).
  • Schedule deliveries for off-peak hours; receive one delivery at a time; staff must be empowered to accept/reject/sign.
  • Recall protocol:
    • Identify recalled item, segregate/label “Do Not Use/Do Not Discard,” do NOT use or throw out until guidance, record lot/date & follow vendor/authority instructions.
  • Temperature criteria at receipt:
    • Cold TCS ≤ 41∘F41^{\circ}F
    • Hot TCS ≥ 135∘F135^{\circ}F
    • Frozen = solid, no ice crystals, no fluids pooled.
  • Packaging: reject if punctured, torn, water-stained, dirty, leaking, swollen can ends, rust, dents, missing/expired code; signs of pests.
  • Shellfish/fish identification tags must be kept 90 days after last product is used (trace-back for outbreaks).

Storage

  • General: • FIFO (First In, First Out). • TCS, ready-to-eat food prepped in-house & held > 24 h must have date mark: discard after 7 days (day 1 = prep/open date). • Store 6 in (15 cm) off floor & away from walls. • Keep raw animal products below RTE food in this top-to-bottom refrigerator order (based on minimum cook temp):
    1. Ready-to-eat
    2. Whole fish
    3. Whole cuts of beef/pork
    4. Ground meat/fish
    5. Poultry (whole & ground)
  • Dry storage: 50∘F–70∘F50^{\circ}F – 70^{\circ}F (10–21 °C); low humidity; ventilated; no chemicals; out of sunlight; 6 in off floor.
  • Randomly monitor internal temps of stored TCS foods; do not overload units; keep doors closed.

Preparation & Thawing

  • Approved thawing methods for TCS food:
    1. In refrigerator ≤ 41∘F41^{\circ}F
    2. Submerged under running potable water ≤ 70∘F70^{\circ}F; water velocity must flush loose particles; ≤ 4 h including time to prep/cook.
    3. In microwave if the product will be cooked immediately afterward.
    4. As part of the cooking process (e.g.
      frozen patties to grill, frozen fish to fryer).
  • Salads containing TCS ingredients (chicken, tuna, egg, pasta, potato): use properly cooked/cooled leftovers; never past use-by.
  • Eggs:
    • Use pasteurized eggs/egg products for dishes not fully cooked (Caesar dressing, hollandaise, tiramisu, etc.) or when serving high-risk populations.
    • Pooled eggs must be pasteurized or cooked promptly.
  • Produce:
    • Prep away from raw meat; clean & sanitize surfaces; wash under running water before cutting/combining; pull apart leafy greens & rinse thoroughly.

Cooking Requirements (Minimum Internal Temperatures)

  • Poultry, stuffed items, dishes containing previously cooked TCS food, microwave-cooked TCS food:
    165∘F (74∘C)165^{\circ}F\ (74^{\circ}C) instantaneous (new FDA wording – no 15 s hold).
  • Ground meat, injected meat, mechanically tenderized meat, ratites, hot-held shell eggs:
    155∘F (68∘C)155^{\circ}F\ (68^{\circ}C) for 17 s (updated from 15 s).
  • Seafood, whole cuts of beef/veal/pork/lamb, game, immediate-service shell eggs:
    145∘F (63∘C)145^{\circ}F\ (63^{\circ}C) for 15 s.
    Roasts: 145∘F145^{\circ}F for 4 min OR alternative time/temperature combos (e.g. 130∘F130^{\circ}F for 112 min112\text{ min} – often sous-vide / reassured by HACCP).
  • All other hot-held/RTE fruit, vegetables, grains, legumes: 135∘F (57∘C)135^{\circ}F\ (57^{\circ}C).

Cooling & Reheating

  • Safe cooling methods: smaller portions, shallow pans, ice-water bath, stirring with ice paddles, blast/tumble chiller; combine methods for speed.
  • Reheating for hot holding: heat to 165∘F (74∘C)165^{\circ}F\ (74^{\circ}C) for 15 s within 2 h; discard if not reached.

Holding & Serving

  • Hot holding: ≥ 135∘F135^{\circ}F; cold holding: ≤ 41∘F41^{\circ}F.
  • Check temps at least every 4 h (preferably every 2 h to allow corrective action).
  • Never reheat in equipment not designed for it (e.g.
    steam table).
  • Utensils: use separate, cleaned/sanitized utensil per product; clean every 4 h of continuous use.
  • Bare-hand contact with RTE food discouraged; if allowed, operation must have written policies & regulatory approval.
  • Dish & flatware handling: touch handles/edges/bottom ONLY; ice only with scoop or tongs (store scoop outside ice bin).

Self-Service (Buffets, Food Bars)

  • Primary defense = continuous monitoring by trained staff.
  • Sneeze guards: leading edge 14 in (36 cm) above counter & 7 in (18 cm) beyond food.
  • Label every item; prohibit reuse of plates/flatware.

Holding WITHOUT Temperature Control (Special Rule)

  • Cold TCS food (e.g.
    picnic potato salad): may be held up to 6 h if:
    • It starts at ≤ 41∘F41^{\circ}F and
    • Never exceeds 70∘F70^{\circ}F – if it hits >70∘F>70^{\circ}F revert to 4 h rule.
  • Hot TCS food without control: maximum 4 h.

Chemical, Cleaning, Pest & Utilities

  • Chemicals: store away from food; clearly labeled if not in original container; if locked, someone on-site must possess a key.
  • Vomit/diarrhea events: operation must have written cleanup procedures including PPE, disposal, disinfection.
  • Master Cleaning Schedule: lists what/when/how/who for every item; employees’ role = execute the schedule.
  • Plumbing, electrical, gas, or pest issues → always call a licensed professional; staff should not DIY pesticide or utility repairs.

Food Safety Management Systems & Variances

  • Variance required for specialized processes (smoking for preservation, curing, ROP/sous-vide, sprouting seeds, processing game, live tank shellfish, etc.).
    • Request goes to state/local regulatory authority.
    • Must submit a HACCP plan or equivalent showing safe controls.

Regulations & Agencies

  • USDA: inspection of meat,poultry,eggs‾\underline{meat, poultry, eggs} (shell & liquid products).
  • FDA: inspects all other food; publishes FDA Model Food Code (guidance – not federal law unless adopted by state).
  • CDC: investigates outbreaks & epidemiology – BUT you report incidents to local/state health department, not directly to CDC.

Exam Tips & Common Tricky Questions

  • Cold-holding 6-hour exception often missed; remember the ≤ 70∘F70^{\circ}F requirement.
  • Thermometer accuracy ±2∘F\pm 2^{\circ}F (food) vs ±3∘F\pm 3^{\circ}F (air).
  • Raw storage order top → bottom; 6 in off floor applies even to #10 cans & individually wrapped flatware – ServSafe may phrase oddly.
  • Employees only “execute” master cleaning program; they don’t design it.
  • Written vomit/diarrhea cleanup procedure is mandatory.
  • For ANY variance or unusual process, the universal answer: contact your state/local regulatory authority and supply a HACCP plan.

Miscellaneous Anecdotes & Real-World Notes

  • Many operators now prefer paper towels over air dryers to avoid airborne contamination.
  • Instructor stories: carrying a finger cot, surgeon glove powder vs kitchen glove debates, Down-syndrome group incident emphasizes PPE & cleanup plan.
  • Mongolian BBQ display illustrates perceived risk of raw foods near ready-to-eat areas → underscores importance of monitoring & cooking temps.
  • ServSafe is known for distractor/trick wording; choose “best” or “least-incorrect” answer when multiple seem right.
