Why serve pasteurized juice to children and the elderly?

Pasteurization kills bacteria that could cause illness in high-risk guests

How does proper cooling keep food safe?

It keeps food out of the temperature danger zone where bacteria grow

More time in the danger zone = more growth

Pathogens multiply quickly when time increases

Pathogens grow fastest between 70°F and 125°F

Control time and temperature to stay safe

Prevents cross-contamination

Thermometers touch many foods

Rice held on a buffet line

Must reach 135°F for safety

Why limit time food spends in the danger zone?

The less time bacteria have to grow, the safer the food

Why use pasteurized eggs in dishes that aren't cooked fully?

Pasteurized eggs are treated to destroy Salmonella

A hamburger patty

Must reach 155°F for 17 seconds

Parasites are prevented mainly through supplier approval and correct cooking

Some seafood must be frozen first if eaten raw

Why use shallow pans for cooling food?

Shallow pans cool food faster than deep pans

Prepping salad before raw chicken

This reduces cross-contamination risk

How does time-temperature abuse cause foodborne illness?

Bacteria grow when food stays too long in the temperature danger zone

What happens if food is left too long in the danger zone?

Bacteria multiply and can cause foodborne illness

Why is allergen cross-contact dangerous?

Even small amounts of an allergen can cause a severe reaction

Chicken salad stored for 10 days

Must be thrown out

Why should thermometers be cleaned and sanitized before use?

To prevent cross-contamination between foods

Parasites need a host to live and reproduce

They are often found in seafood, wild game, and produce washed with unsafe water

Why record temperatures?

To know how long food has spent in the temperature danger zone

Why use special controls for sous vide cooking?

The food is sealed and cooked slowly, so temperature and time must be carefully controlled

Fish and whole cuts need less heat than poultry

Pathogens are usually on the surface

FAT TOM represents the six conditions that bacteria need to grow

You can usually only control time and temperature

Why divide large food into smaller containers for cooling?

To cool it faster, less time in the temperature danger zone

Barriers like glass or metal block readings

Infrared thermometers can’t read through them

Raw chicken juice on a cutting board used for salad

This is an example of cross-contamination

Why separate raw seafood, poultry, and meat during prep?

Each type can carry different pathogens that can spread if mixed

Toxins in fish or shellfish can cause illness quickly

Cooking and freezing do not make toxins safe

Soup at 120°F for 2 hours

Reheat it or throw it out

Why must cooks use separate equipment for allergen orders?

To prevent allergen cross-contact with other foods

Rinsing lettuce leaves before salad prep

Removes dirt and pathogens

Soup stored in deep plastic bins

Slows down cooling

Why discard food that’s been in the danger zone too long?

Because bacteria may have grown to unsafe levels

Bimetalic-stemmed thermometers are good for thick foods, like roasts

Insert stem up to the dimple

Smoking food for preservation

Requires a variance and HACCP plan

Prep ready-to-eat food before raw food

This lowers contamination risk

Grinding meat spreads pathogens inside

Higher cooking temperature required for ground meat

Frozen chicken thawed under running water

Must not exceed 41°F for more than 4 hours

Why calibrate thermometers regularly?

To make sure temperature readings are accurate

Why cool food from 135°F to 70°F within 2 hours?

To limit its time in temperatures that bacteria grow fastest

Check temperatures in the thickest part of food

Center is usually best

Why use approved additives in food?

Unapproved additives can be toxic or illegal

Returning food to the cooler quickly

Prevents time-temperature abuse

Immersion probes only measure surfaces

Do not use for soup or meat interiors

Soup cooling from 135°F to 70°F

Must happen within 2 hours

Microwaved chicken pieces

Must reach 165°F

Poultry and stuffed foods need the highest cooking temperature

It kills Salmonella and other pathogens

A beef roast

Requires longer time at 145°F

Why stir food while cooling?

To release heat and cool food faster

Why cool food from 135°F to 41°F within 6 hours?

To limit its time in the temperature danger zone

Reducing batch sizes lowers time in unsafe temperatures

Helps maintain food safety

A grilled steak

Safe to eat at 145°F for 15 seconds

Probe needed only at the tip

Thermocouples and thermistors are good for thick and thin foods

Cross-contact example: cooking shrimp and chicken in the same fryer oil

Allergen proteins transfer between foods

Abuse occurs anytime food is not handled safely

These mistakes add up

Cutting boards with colors for different foods

Colors help keep raw and ready-to-eat food separate

Why never use glass thermometers in food?

They can break and contaminate food with glass

Why use a thermometer probe for thick food?

It checks the center temperature where bacteria survive longest

Why must staff know the Big Nine food allergens?

So they can prevent serving food that causes allergic reactions

Why use pasteurized eggs in nursing homes or hospitals?

Older adults are at higher risk for Salmonella infection

A sanitized cutting board

Prevents cross-contamination when preparing food

Chili cooled in 7 hours

Must be discarded

Yellow for poultry, red for meat, green for produce

Color coding prevents cross-contamination

Caesar dressing made with eggs

Use pasteurized eggs for safety

Why must food reach its minimum internal cooking temperature?

To kill bacteria and make food safe to eat

Insert thermometer to the dimple

The sensing area runs from tip to dimple

Why keep emergency contact info for allergic reactions?

Staff can respond fast in case of an emergency

Why discard ice used to cool food?

It can contain bacteria or dirt from containers

Chicken breast cooked fully

Must hit 165°F to kill pathogens

Pathogens grow fastest in what range?

Between 70°F and 125°F

Meat sauce cooled in sink of ice water

This speeds up cooling

Precooked chicken breasts or bagged lettuce

These reduce the need for prep steps

Why use color-coded cutting boards?

To stop cross-contamination between raw and ready-to-eat foods

Take readings in multiple spots

Temperature may vary inside food

Plant-based foods can still carry pathogens

Heating makes them safe for hot holding

Reheated soup on buffet line

Must reach 165°F

How can cross-contamination happen during prep?

When the same tools or surfaces touch raw and ready-to-eat food

Microwaves cook unevenly, so food needs higher heat

Stirring and standing time help even cooking

Hot soup held below temp for 2 hours

Can be reheated safely

A prep sink with cold running water

Can be used to thaw TCS food safely

Regular checks protect food throughout flow

Consistency is key

Thawing vacuum-packed salmon

Remove from package for safety

Pasta salad cooling

Must reach 41°F within 4 hours

Buying precooked or prewashed foods reduces handling

Less handling means less contamination risk

Partially cooked chicken wings

Must be finished later

Why wash fruits and vegetables before cutting or cooking?

Dirt or pesticides on the surface can contaminate the inside

Thermocouples and thermistors

Work for thick and thin foods

Soup stirred with ice paddle

Helps food cool faster

Why label packaged foods with allergen information?

Labels warn customers about ingredients that may trigger reactions

Cheese sticks reheated

Only need to reach 135°F

Sneezing on ready-to-eat food

Food must be discarded

Why avoid pooling raw eggs?

Bacteria from one egg can spread to the rest of the batch

Rinsing alone after raw chicken prep

This does not remove pathogens like Salmonella
