Sample Questions

Question 1

What does the term 'sanitize' mean in a food service context?

Answer: Sanitizing means reducing the number of harmful microorganisms on a surface to safe levels as defined by public health standards. It does not necessarily kill all microorganisms.

Question 2

What are the two methods used to sanitize food contact surfaces?

Answer: The two methods are heat sanitizing (using hot water) and chemical sanitizing (using approved sanitizing chemicals). Both must achieve the required reduction in pathogens.

Question 3

Why must a surface be cleaned BEFORE it is sanitized?

Answer: Dirt and organic matter block sanitizers from reaching and killing pathogens, making the sanitizer ineffective. A sanitizer can only work properly on a clean surface.

Question 4

What is the difference between cleaning and sanitizing?

Answer: Cleaning removes visible dirt and food residue, while sanitizing reduces harmful microorganisms to safe levels. Both steps are necessary — sanitizing alone is ineffective on a dirty surface.

Question 5

Which surfaces in a food establishment MUST be sanitized?

Answer: All food contact surfaces — including cutting boards, knives, prep tables, equipment, and utensils — must be cleaned and sanitized. Non-food contact surfaces only need to be cleaned.
