Trang 3Let’s Look at Cleaning and Sanitation
Cleaning removes the visible soil and food particles
from a surface.
What is the difference between cleaning and sanitizing?
Sanitizing reduces the number of microorganisms
(bacteria, viruses, etc.)
20140630
Trang 4Something that looks clean does not mean it is sanitary Billions of microorganisms may be present even though they are not visible to the naked eye
Both cleaning and sanitizing are essential in preventing foodborne illness
Just because…
Trang 5When should I clean and sanitize materials?
20140630
∗ Each time there is a change from working with raw
foods to working with ready-to-eat foods
∗ Between uses with raw fruits and vegetables and
with potentially hazardous foods
∗ Before using or storing food thermometers (after
each use)
∗ Any time contamination may have occurred
∗ Before each use with different types of raw animal food, except in contact with a succession of different raw animal foods, in which the second food requires a higher cooking temperature than the first food

Trang 7∗ You should clean surfaces and equipment at least every 24 hours or any time
contamination may occur.
dispensers
nozzles & syrup dispenser tubes, cooking oil storage tanks & distribution lines, coffee
bean grinders, and water vending equipment, as specified by the manufacturer or as
necessary to preclude accumulation of soil or mud
20140630
When should I clean and sanitize surfaces and equipment that contacts non-potentially
hazardous foods?
Trang 8∗ Make sure that you can’t contaminate food during and with the use of cleaners and sanitizers
Be careful…
Trang 9∗ Always store chemicals safely away from all food.
20140630
Proper Chemical/Cleaning Storage
Trang 10∗ Don’t use chemical if you haven’t properly been trained
∗ Always put food and packaging away before chemical usage
∗ Use only approved chemicals for the task you are doing
∗ Use only according to the manufacturer label
∗ Always make sure there is a proper label attached to the container
∗ Know where to locate the Material Safety Data Sheets (MSDS) for all chemicals

Cleaning and Sanitizing Using a 3 Compartment Sink.
20140630
There are five steps to correctly utilize a 3 compartment sink
Trang 12Step 1: Pre-scrape
- Rinse, scrape, or soak all items before washing
- Have a waste receptacle near the 3 compartment sink if necessary
Step 2: Wash
- Wash in hot water, at least 110° F, with detergent.
3 Compartment Sink Process
Trang 13Step 3: Rinse
20140630
Rinse off soap residue using clear, warm water.
Step 4: Sanitize
Sanitize in warm water, at least 75° F*, with:
- 50 ppm chlorine, immersed for 1 minute;
or
- 12.5 ppm iodine, immersed for 1 minute;
or
- 200 ppm QAC, immersed for 1 minute
*Sanitizing instructions differ per product, be sure to
check the manufacturer’s directions.
3 Compartment Sink Process
Trang 14Key Tip to Sanitizing!
It is important to monitor the sanitizing solution
to ensure the correct amount is added to the
water:
- too much sanitizer is toxic
- too little is unsanitary
Use test strips to monitor the pH of your sanitizer solution
Trang 15Step 5: Air Dry
20140630
Air dry all equipment and utensils before stacking to eliminate the growth of microbes

Trang 16Let’s look at:
Dish Machine Washing and Sanitizing
There are two kinds of commercial dish machines: chemical sanitizing machines and hot-water sanitizing machines
Chemical Sanitizing
These machines use chlorine-based chemicals dispensed during the final rinse to sanitize equipment The chemical level should be 50 ppm in the final rinse water As with manual dish washing, sanitizer strength should be monitored using test-strips
Hot Water Sanitizing
These machines use very hot water during the final rinse to sanitize equipment This water should be 180° F to effectively
Trang 17Dish machines should be monitored for:
20140630
- food debris and grease residue.
- proper soap amount dispensed during wash cycle.
- sanitizer strength (chemical, sanitizing only).
- wash and final rinse temperatures.
