3 - Compartment Sink: Water Temperature - ✔✔110 F
3 - Compartment Sink: Sanitation: Concentrations - ✔✔Chlorine: 50-200 ppm
Quaternary ammonium: 200 ppm
Iodine: 12.5-25 ppm
Why do I need to sanitize utensils or equipment if I will be using it for cooking? -
✔✔There is no guarantee that the heat involved in cooking will heat all parts of the
utensils or equipment to a temperature that will kill the harmful microorganisms. Also,
the utensils or equipment may not be used for cooking. instead, the utensils or
equipment may be used for mixing with no heat involved.
What are the common types of sanitizers to use? - ✔✔Hot water
Chlorine
Iodine
Quaternary Ammonium Compound (QUATS)

, What are the advantages of hot water sanitizer? - ✔✔Mainly used in mechanical
dishwasher; clean in place; easy to measure temperature with built-in thermometer
What are the advantages of chlorine sanitizer? - ✔✔Relatively inexpensive; kills most
microorganisms; does not form film; easy to measure with test strips
What are the advantages of iodine sanitizer? - ✔✔Stable, long shelf life; non-corrosive;
kills most organisms including yeasts and molds; color gives indication or strength
What are the advantages of QUATS sanitizer? - ✔✔Non-corrosive; less affected by
organic matter; can be applied as a foam for visual control; effective odor control;
effective against Listeria monocytogenes, a resistant type of bacteria able to grow at
lower temperatures
What are the disadvantages of hot water sanitizer? - ✔✔May cause burns; may need
large hot water heater and booster
What are the disadvantages of chlorine sanitizer? - ✔✔Corrodes metal and weakens
rubber; breaks down quickly (need to add more chlorine often); irritant to skin, eyes
and nose; effective only for water below pH 10; may leave water spots
What are the disadvantages of iodine sanitizer? - ✔✔Expensive; may stain plastics and
porous materials; does not work above 120F
What are the disadvantages of QUATS sanitizer? - ✔✔Inactivated by most detergents;
may be ineffective for certain microorganisms; may be ineffective in hard water (lots of
minerals); relatively expensive
Why must I test the concentration of the sanitizer with test strips? - ✔✔The amount of
sanitizer added to the water (concentration) is critical. Too little sanitizer will not be
effective and may cause food poisoning. Too much sanitizer may cause taste/odor
problems, toxicity, and waste of money. Test strips must be used to test the strength of
