CFPM Cleaning & Sanitizing 2

Question 1

Which factor most directly affects the effectiveness of a chemical sanitizer?

Accepted Answer

Concentration of the solution

Answer

Concentration is the most critical factor — too low won't sanitize, too high can be unsafe or leave harmful residues.

Question 2

What is the correct order of steps in a manual three-compartment sink?

Accepted Answer

Wash, rinse, sanitize, air dry

Answer

The correct sequence is wash to remove soil, rinse to remove detergent, sanitize to kill pathogens, then air dry.

Question 3

At what minimum temperature must water be maintained in the wash compartment of a three-compartment sink?

Accepted Answer

110°F (43°C)

Answer

The wash water must be at least 110°F (43°C) to effectively loosen grease and food soil from surfaces.

Question 4

Why must food-contact surfaces be rinsed after washing and before sanitizing?

Accepted Answer

To remove detergent that could neutralize the sanitizer

Answer

Detergent residue can react with and neutralize chemical sanitizers, reducing their effectiveness.

Question 5

What does the term 'sanitizing' mean in a food safety context?

Accepted Answer

Reducing pathogens on a surface to safe levels

Answer

Sanitizing reduces the number of microorganisms to levels considered safe by public health standards, but does not sterilize.
