question
Sanitizing
answer
reduces pathogens on a surface to a safe levels
question
Chemical Sanitizing
answer
Tableware, utensils, & equipment can be sanitized by soaking in sanitized solution or spraying them.
question
3 common types of Chemical Sanitizers:
answer
Chlorine (bleach) , Iodine, Quats -Room temperature water is best for use with sanitizers.
question
Sanitizer Effectiveness is based on:
answer
-Water Temperature -Water pH -Water Hardness -Concentration -Contact Time -Selecting the correct sanitizer
question
Chlorine guidelines:
answer
Water temp= 75-115ºF *adversely affected by temp over 115ºF pH= ≤ 8 Concentration= 50-99 ppm Contact Time= ≥ 7 seconds
question
Iodine guidelines:
answer
Water Temp= 68ºF pH= ≤5 Concentration= 12.5-25 ppm Contact Time= ≥30 seconds
question
Quats Guidelines:
answer
Water Temperature= 75ºF pH= manufacturer's recommendation Water Hardness= ≤500 ppm Contact Time= ≥30 seconds
question
When checking sanitizer pH make sure
answer
you are using strips specific to each sanitizer
question
How to Clean & Sanitize a Surface:
answer
1.) Scrape or remove food bits from the surface. 2.) Wash surface w/ correct cleaning tool & solution. 3.)Rinse surface w/clean water & correct cleaning tool. 4.) Sanitize ENTIRE surface w/correct solution,pH,tool 5.) Air dry.
question
When to Clean & Sanitize:
answer
-After they are USED -BEFORE food handlers start working w/DIFFERENT type of food. -Any time food handlers are interrupted during a task & the items being used MAY have been contaminated -After FOUR hours if items are in constant contact

question
A Three-Compartment Sink:
answer
- Clean and sanitize each sink and drain board - Fill the First sink with Detergent and water at least 110°F - Fill the Second sink with Clean Water - Fill the Third sink with Water and Sanitizer to the correct concentration - Provide a Clock with a second hand to let food handlers know how long items have been in the sanitizer
question
High Temp Machines to clean & sanitize
answer
- Water temperature is critical - Final Rinse must be 180° F - Water temps that are too high will bake on food making it harder to clean - May need a hot water booster
question
Chemical Sanitizing Machines
answer
Wash at a much lower temperature- no less than 120°F "Wet Nesting" - stacking and storing wet plates is acceptable but drain them
question
Dishwashing Machine Operation Guidelines:
answer
-Cleanliness: clean as often as needed -Preparation: scrape,rinse, or soak items before washing -Loading: load so that all areas are reached -Air-drying: Never use towel to dry -Monitor: check water temps, pressure, and sanitizing levels.
question
Implementing a Cleaning Plan
answer
• Walk through every area of the facility • Look at the way cleaning is currently being done • Estimate the amount of time & what skills are needed for each task • Create a master cleaning schedule
question
MASTER CLEANING SCHEDULE
answer
• What should be cleaned • Who should clean it • When should it be cleaned • How should it be cleaned • Monitor the program
question
Which thermometer should be used to monitor the temperature of the sanitizing rinse in a dishwashing machine?
answer
Maximum Registering
question
What is sanitizing ?
answer
Reducing pathogens to safe levels
question
If food-contact surfaces are in constant use, how often must they be cleaned & sanitized?
answer
Every 4 hours
question
What must food handlers do to make sure sanitizing solution for use on food-contact surfaces has been made correctly?
answer
Test the solution with a sanitizer kit.
question
A food handler was assigned to clean a slicer that was too difficult to move. The slicer was unplugged. Then the removable parts were taken off the slicer & cleaned and sanitized in a three-compartment sink. Food bits on the slicer were removed. After the machine was wiped down w/detergent and water, it was sanitized and allowed to air-dry. Then the food handler put the machine back together. What mistake did the food handler make?
answer
Failed to rinse the machine after wiping it down with detergent and water.
