Foodborne Illness and Food Safety Hazards

  • Temperature danger zone is 41°F to 135°F (5°C to 57°C); TCS food must not accumulate more than 4 hours in this range.

  • FATTOM growth factors: Food, Acidity (pH 4.6–7.0), Time, Temperature, Oxygen, Moisture (water activity 0.85 or higher); eliminating any one factor controls growth.

  • FDA Big 6: Salmonella Typhi, nontyphoidal Salmonella, Shigella spp., E. coli O157:H7, hepatitis A, and norovirus - a diagnosis or symptom of any requires exclusion of the food employee.

  • Viruses (norovirus, hepatitis A) do not multiply in food; they spread fecal-orally via hands and have a very low infectious dose (norovirus roughly 10–100 particles).

  • Spore formers survive normal cooking: Clostridium botulinum (anaerobic, low-acid, aw 0.85+), Clostridium perfringens (cooling abuse), Bacillus cereus (cooked rice).

  • Preformed toxins: Staphylococcus aureus (onset 1–6 hours, from hands and skin lesions) and Bacillus cereus emetic type (1–6 hours, reheated rice); both are heat-stable.

  • Scombroid (histamine) poisoning comes from tuna, mahi-mahi, and mackerel held above 41°F; the histamine formed is not destroyed by cooking.

  • Big 9 allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame.

  • High-risk populations are children under 5, adults over 65, pregnant women, and immunocompromised people; never serve them raw or undercooked animal foods.

Food Protection: Purchasing, Receiving, and Storage

  • Receiving standards: cold TCS food at 41°F or lower, frozen food at 0°F or lower and solidly frozen, hot TCS food at 135°F or higher, raw shell eggs and milk at 45°F or lower.

  • Reject deliveries with swollen, leaking, or seam-dented cans, torn packages, pest evidence, missing labels or dates, or product that has thawed and refrozen.

  • Shellstock tags stay attached to the container until it is emptied, then are kept 90 days from the date the last shellfish from that lot was sold or served.

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

  • Date marking: ready-to-eat TCS food prepared on site and held more than 24 hours is marked and discarded within 7 days at 41°F or lower, counting the prep day as day 1.

  • Dry storage: 50°F to 70°F, about 50–60% humidity, food at least 6 inches off the floor and away from walls.

  • FIFO: first in, first out - rotate stock so older product is used before newer product.

  • Thermometers: bimetallic stemmed type accurate to ±2°F, calibrated in an ice-water slurry at 32°F, and probed into the thickest part of the food.

  • Chemicals are stored below and away from food, in original labeled containers, never in unlabeled bottles or food containers.

Food Preparation, Handling, and Service

  • Two-stage cooling: 135°F to 70°F within 2 hours, then 70°F to 41°F within 4 more hours (6 hours total), with times recorded.

  • Reheating for hot holding: 165°F for 15 seconds within 2 hours; microwave reheating also requires covering, stirring, and a 2-minute stand time.

  • Cooking minimums: poultry and stuffed foods 165°F instantaneous; ground meat 155°F for 17 seconds; whole-muscle beef/pork and fish 145°F for 15 seconds; commercially processed ready-to-eat food 135°F.

  • Hot holding at 135°F or higher and cold holding at 41°F or lower, with internal temperatures checked and logged at least every 4 hours.

  • Approved thawing methods: refrigeration at 41°F or lower, running water at 70°F or lower, microwave followed by immediate cooking, or as part of the cooking process.

  • No bare-hand contact with ready-to-eat food; use utensils, deli tissue, or gloves, and change gloves after handling raw animal foods or touching the face, phone, or trash.

  • Handwashing: soap and water at 100°F or hotter, scrub 10–15 seconds, at least 20 seconds total, at a sink used only for handwashing.

  • Time as a public health control: 4 hours maximum without temperature control before discard, or 6 hours if food starts at 41°F or lower and never exceeds 70°F.

  • Parasite destruction for fish served raw: freeze at -4°F for 168 hours (7 days) or at -31°F for 15 hours.

Facilities, Equipment, Cleaning, Sanitizing, and Pest Management

  • Cleaning removes visible soil and grease; sanitizing then reduces pathogens on a clean surface by 99.999% (5-log reduction).

  • Chemical sanitizer concentrations: chlorine 50–100 ppm, quaternary ammonium 200–400 ppm, iodine 12.5–25 ppm, each verified with the matching test strip.

  • Hot-water sanitizing: 171°F for at least 30 seconds by immersion, or a 180°F final rinse at the manifold in a mechanical dish machine.

  • Three-compartment sink sequence: scrape, wash in detergent at 110°F or hotter, rinse, sanitize by immersion per label, then air dry on a rack.

  • Food-contact surfaces in continuous use with TCS food are cleaned and sanitized at least every 4 hours, and whenever switching between raw animal foods.

  • Backflow prevention: an air gap of at least twice the supply pipe diameter and never less than 1 inch, or an approved vacuum breaker.

  • Pest exclusion: self-closing doors, 16-mesh screens, air curtains, and sealing gaps of 1/4 inch or larger; live pests or rodent droppings are critical violations.

  • Lighting: at least 50 foot-candles at food preparation surfaces and handwashing sinks, at least 10 foot-candles in dry storage.

  • Equipment must be smooth, nonabsorbent, corrosion-resistant, easily cleanable, and certified to NSF/ANSI or an equivalent standard.

Regulatory Compliance, Inspections, Employee Health and Training

  • The FDA Food Code is a model regulation with no federal enforcement power; state and local jurisdictions adopt or adapt it and inspect against their own rules.

  • HACCP seven principles: hazard analysis, critical control point identification, critical limits, monitoring, corrective actions, verification, recordkeeping.

  • Reportable employee conditions: vomiting, diarrhea, jaundice, sore throat with fever, infected wound, and boils or lesions on the hands.

  • Exclusion removes the employee from the premises; restriction keeps them away from food, utensils, and equipment - a Big 6 diagnosis generally requires exclusion until the regulatory authority clears the worker.

  • Symptoms of vomiting or diarrhea require exclusion until 24 hours after they resolve; norovirus requires 48 hours under the 2022 Food Code.

  • Imminent health hazards such as fire, flood, water outage, sewage backup, or heavy pest infestation require stopping operations and notifying the regulatory authority.

  • Critical violations pose immediate risk (improper holding temperatures, bare-hand contact with ready-to-eat food) and are corrected on the spot or the food is destroyed.

  • The person in charge must demonstrate food safety knowledge, apply active managerial control, ensure employee illness reporting, and maintain training and temperature records.

  • Retention examples: shellfish tags 90 days, HACCP and cooling logs per the written plan, and training certificates as required by the jurisdiction.
