Every guest at your operation trusts you to keep them safe. A foodborne illness is a disease transmitted to people through food. Your job as a food handler is to understand the hazards and avoid the four unsafe practices that cause most foodborne illness outbreaks.

The 3 Types of Food Safety Hazards

  • Biological — pathogens: bacteria, viruses, parasites, and fungi. The greatest threat.
  • Chemical — cleaners, sanitizers, polishes, lubricants, and toxic metals from cookware.
  • Physical — foreign objects: hair, dirt, bandages, broken glass, metal staples, fish bones.

The 4 Unsafe Practices (Most Common Causes)

  • Poor personal hygiene — transferring pathogens from your body to food. #1 cause of outbreaks.
  • Cross-contamination — transferring pathogens from one surface or food to another.
  • Time-temperature abuse — letting food stay too long at temperatures where pathogens grow.
  • Poor cleaning and sanitizing — transferring pathogens from unclean surfaces to food.
🛡️ Your RoleKeep your eyes open for possible problems. Knowing the hazards is just the start — the next step is working safely every shift.

🦠 Biological Hazard

Bacteria, viruses, parasites, fungi, and toxins from plants/seafood. The #1 threat to food safety.

⚗️ Chemical Hazard

Cleaners, sanitizers, pesticides, lubricants, and toxic metals that leach from cookware when used incorrectly.

🔧 Physical Hazard

Foreign objects — hair, glass, staples, bandages — or natural items like fish bones in fillets.

⚠️ 4 Unsafe Practices

Poor hygiene, cross-contamination, time-temperature abuse, and poor cleaning/sanitizing.

📖 Scenario

During the lunch rush, a cook cuts raw chicken on a cutting board, then immediately uses the same board — without washing or sanitizing it — to slice cooked sandwiches for the buffet line. By the end of the shift, six guests report symptoms of food poisoning.

Which unsafe practice caused this? Cross-contamination. Raw chicken contains pathogens (like Salmonella) that were transferred to the ready-to-eat sandwiches via the unwashed cutting board. The fix: clean and sanitize all food-contact surfaces between each type of food.

Proper Handwashing — 5 Steps

  1. Wet hands with running water as hot as you can comfortably stand
  2. Apply enough soap to build up a good lather
  3. Scrub for 10–15 seconds — clean under fingernails and between fingers
  4. Rinse with running warm water
  5. Dry with a single-use paper towel or hand dryer (use the towel to turn off the faucet)
🚫 Hand Antiseptic ≠ HandwashingHand sanitizer is used AFTER washing — never instead of it. Wait for it to dry before touching food or putting on gloves.

When to Wash Hands (Key Moments)

  • Before starting work and before putting on gloves
  • After using the restroom
  • After handling raw meat, poultry, or seafood (before and after)
  • After touching your hair, face, or body
  • After taking out garbage, handling money, smoking, eating, or using a phone

Gloves — Rules to Follow

  • DO NOT touch ready-to-eat food with bare hands — use single-use gloves, tongs, or deli sheets
  • NEVER rinse, wash, or reuse gloves. NEVER blow into gloves.
  • Change gloves when dirty/torn, between different tasks, before allergen orders, and after handling raw proteins

Illness Reporting

Tell your manager if you have: vomiting, diarrhea, jaundice (yellowing of skin/eyes), or a sore throat with a fever. You could spread pathogens to food and coworkers while sick.

🙌 Handwash = 10–15 sec scrub

5 steps: Hot water → Soap → Scrub 10–15 sec → Rinse → Dry with paper towel. Use towel to turn off faucet.

🧤 Bare Hands = No RTE Food

Never touch ready-to-eat food with bare hands. Use gloves, tongs, or deli tissue. Single-use only — never rewash or reuse.

💊 Report Illness

Vomiting, diarrhea, jaundice, or sore throat with fever — always tell your manager before handling food.

👗 Appearance Rules

Clean hair covering (hat/hairnet), clean clothes daily, no jewelry except plain band, no nail polish or false nails.

📖 Scenario

Jasmine has been feeling ill since last night with stomach cramps and diarrhea. She comes in to her morning shift anyway because she doesn't want to miss hours. Her manager doesn't ask about her health. During the shift she makes sandwiches for the lunch rush.

What went wrong — and what should have happened? Jasmine should have reported her symptoms to her manager before starting. Diarrhea is an illness exclusion symptom — she should not be handling food at all. The manager should ask food handlers about their health at the start of each shift, and Jasmine should have stayed home or been sent home immediately.

2. You must tell your manager if you experience any of these symptoms EXCEPT:

TCS food (Temperature Control for Safety) allows bacteria to grow if not kept at safe temperatures. Common examples: milk & dairy, poultry, meat (beef, pork, lamb), fish, shellfish, shell eggs, baked potatoes, cooked rice/beans, sliced melons, cut tomatoes, and tofu.

Temperature Danger Zone: 41°F – 135°F

Pathogens grow rapidly in this range. Keep TCS food OUT of the danger zone. If food is at an incorrect temperature, tell your manager — you may need to cook, reheat, or throw it out.

Minimum Internal Cook Temperatures

FoodTempTime
Poultry (whole, ground, duck)165°F<1 second
Ground meat (beef, pork, other)155°F17 seconds
Seafood, steaks/chops of pork/beef/veal/lamb145°F15 seconds
Roasts of pork, beef, veal, lamb145°F4 minutes
Fruit, vegetables, grains, beans (for hot holding)135°FInstant

Cooling, Holding & Reheating

  • Hot holding: 135°F or higher
  • Cold holding / receiving cold TCS food: 41°F or lower
  • Cooling Step 1: 135°F → 70°F within 2 hours
  • Cooling Step 2: 70°F → 41°F within 4 more hours (6 hours total)
  • Reheating for hot holding: 165°F within 2 hours
  • NEVER cool food at room temperature or in large batches — use ice baths, ice paddles, or blast chillers

Safe Thawing Methods (4 Approved Ways)

  1. In the refrigerator at 41°F or lower
  2. Under running drinkable water at 70°F or lower
  3. In the microwave — only if cooking immediately after
  4. As part of the cooking process
⚠️ NEVER Thaw at Room TemperatureThis is time-temperature abuse. TCS food thawed on the counter can reach unsafe temperatures for hours.

🌡️ Danger Zone = 41–135°F

Pathogens multiply rapidly in this range. Keep TCS food out. Check temps in the thickest part of the food.

🐔 Poultry = 165°F

All poultry (whole, ground, duck) must reach 165°F for less than 1 second. Highest cook temp required.

🥩 Ground Meat = 155°F / 17 sec

Ground beef, pork, and other ground meats. Note: Food Handler standard uses 17 seconds (not 15).

❄️ Cool in 6 Hours Total

135→70°F in 2 hrs, then 70→41°F in 4 more hrs. Use ice baths, ice paddles, or blast chiller.

📖 Scenario

After the dinner rush, Marcus puts a full pot of beef chili (still at 135°F) directly into the walk-in cooler without dividing it. The next morning, the center of the pot is still at 80°F — more than 6 hours later.

What went wrong? The chili was never cooled correctly. A large, deep pot holds heat too long. It should have been divided into shallow pans no deeper than 2 inches, placed in an ice water bath, and stirred with an ice paddle to cool quickly. Since it stayed above 41°F for over 6 hours, it must be thrown out — it cannot be safely reheated.

2. Food is being reheated to hold on a steam table. It must reach what temperature?

Cross-contamination is the transfer of pathogens from one surface or food to another. It's one of the leading causes of foodborne illness — and it's almost entirely preventable.

Storage Rules

  • Store food at least 6 inches off the floor in designated storage areas
  • Wrap or cover food before storing it
  • NEVER store food in old chemical containers
  • Store RTE food above raw meat — or use separate storage if possible

Refrigerator Storage Order (Top → Bottom)

  1. Ready-to-eat food (highest)
  2. Whole fish
  3. Whole cuts of beef and pork
  4. Ground meat and ground fish
  5. Whole and ground poultry (lowest)

Prepping Food

  • Wash, rinse, and sanitize cutting boards, knives, and equipment between each product
  • Prep raw meat at a different time than RTE food when using the same table
  • Wash produce in running water slightly warmer than the food

The Big 8 Food Allergens

Milk · Eggs · Fish · Shellfish · Tree nuts (pecans, walnuts, coconut) · Peanuts · Wheat · Soy. Even a tiny amount can cause a reaction or death. Cross-contact (allergen transfer) is different from cross-contamination — allergens are not destroyed by cooking or sanitizing.

🥜 Allergen Special OrdersWash hands and change gloves. Use dedicated equipment. Wash/rinse/sanitize all utensils. Hand-deliver the order directly to the guest. If cross-contact happens — set it aside and tell your manager. If a guest has a severe reaction, call emergency services.

📦 Store 6" Off Floor

All food and non-food items must be stored at least 6 inches off the floor, away from walls, in designated areas.

🥗 RTE Above Raw Proteins

Store ready-to-eat food above raw meat. Lowest shelf = poultry (165°F). Highest shelf = RTE food.

🥜 Big 8 Allergens

Milk, Eggs, Fish, Shellfish, Tree nuts, Peanuts, Wheat, Soy. Cross-contact ≠ cross-contamination. Not destroyed by heat.

🧴 Chemicals = Separate Storage

Store chemicals away from food. Keep in original containers. Transfer containers must be labeled with chemical's common name.

📖 Scenario

A customer tells her server she has a peanut allergy. The server places the order but doesn't mark it as an allergen special order. The cook uses the same unwashed pan that was used for a peanut sauce dish. The customer has a severe allergic reaction.

What should have happened? The server should have clearly identified the allergen order. The cook should have washed hands, changed gloves, and used clean/sanitized equipment. The server should have hand-delivered the dish directly. When in doubt, tell your manager — keeping the guest safe is always the priority.

Cleaning vs. Sanitizing

  • Cleaning — removes food and dirt from a surface. Does NOT make it safe on its own.
  • Sanitizing — reduces pathogens to safe levels. A surface must be CLEAN before sanitizing works.

5-Step Cleaning & Sanitizing Process

  1. Scrape or remove food from the surface
  2. Wash the surface
  3. Rinse the surface
  4. Sanitize the surface
  5. Allow to air-dry

Three-Compartment Sink

  • Sink 1 (Wash): Water at least 110°F + detergent. Scrub with brush or nylon pad. Change water when suds are gone or water is dirty.
  • Sink 2 (Rinse): Clean water (or spray-rinse). Remove all food and detergent.
  • Sink 3 (Sanitize): Water + correct amount of sanitizer — check strength with a test kit. Soak items for the correct time.
  • NEVER rinse items after sanitizing. Air-dry upside down. NEVER towel-dry.

When to Clean & Sanitize

  • After finishing with an item
  • Before starting with a different type of food
  • After any interruption that could have contaminated the surface
  • After every 4 hours if items have been in constant use
🐀 Pest ControlTell your manager immediately if you spot droppings, nests, damage to products or packaging, or cockroach signs (capsule-shaped egg cases, strong oily odor). Remove garbage quickly and keep containers covered.

🧹 Clean FIRST

Cleaning removes dirt. Sanitizing reduces pathogens. You must clean before sanitizing — sanitizing a dirty surface doesn't work.

🚿 3-Comp Sink Order

WASH (110°F+ water + soap) → RINSE (clean water) → SANITIZE (correct concentration) → Air dry upside down.

⏱️ Every 4 Hours

Food-contact surfaces in constant use must be cleaned and sanitized at least every 4 hours — even if they don't look dirty.

🐛 Report Pests

Droppings, nests, damage to packaging, or cockroach signs → tell your manager right away. Never ignore pest signs.

📖 Scenario

During a busy service, a prep cook uses a cutting board to chop raw onions, then garlic, then moves on to slicing cooked chicken without stopping to clean and sanitize. At the end of the shift, she quickly wipes all the boards with a dry towel and calls it done.

What's wrong here? Two problems: (1) Food-contact surfaces must be cleaned and sanitized between different food types — especially before handling ready-to-eat food like cooked chicken. (2) Wiping with a dry towel is not cleaning or sanitizing. The 5-step process must be followed. Towels used for food spills must be stored in sanitizer solution, not used for general wiping.

1. What is the CORRECT order for the three-compartment sink?
2. Food-contact surfaces in constant use must be cleaned and sanitized at minimum every:
