CFPM Cleaning & Sanitizing

Question 1

What is the purpose of cleaning and sanitizing food contact surfaces?

Accepted Answer

To reduce harmful microorganisms.

Answer

Cleaning removes visible dirt, food particles, and grease from surfaces. Sanitizing, which follows cleaning, uses heat or chemicals to reduce the number of harmful microorganisms (pathogens) to a safe level. Both steps are essential to ensure food contact surfaces are hygienic and do not contribute to the spread of foodborne illnesses.

Question 2

What is the recommended concentration of chlorine bleach for sanitizing surfaces?

Accepted Answer

50-100 ppm.

Answer

For effective sanitization of food contact surfaces, chlorine bleach solutions should typically be between 50-100 parts per million (ppm). This concentration is strong enough to kill most harmful bacteria and viruses without leaving excessive chemical residue or being overly corrosive. Always follow manufacturer guidelines and local health codes for specific dilution ratios.

Question 3

Which is more effective: using soap or using a sanitizer?

Accepted Answer

Soap and sanitizer should be used together.

Answer

Soap is a cleaning agent that physically removes dirt, grease, and many microorganisms from surfaces. Sanitizers, on the other hand, are chemical or heat treatments designed to reduce the number of remaining microorganisms to safe levels. Therefore, cleaning with soap first to remove debris, followed by sanitizing, is the most effective two-step process to ensure food contact surfaces are hygienic.

Question 4

What is the correct order for cleaning and sanitizing food contact surfaces?

Accepted Answer

Clean first, then sanitize.

Answer

It is crucial to clean surfaces first to remove visible dirt, food particles, and grease. Sanitizers are most effective on clean surfaces, as organic matter can inactivate them. After cleaning, sanitizing then reduces the number of harmful microorganisms to a safe level, ensuring proper hygiene and preventing the spread of pathogens.

Question 5

How often should food contact surfaces be cleaned and sanitized?

Accepted Answer

After each use or when contamination occurs.

Answer

Food contact surfaces must be cleaned and sanitized frequently to prevent the buildup and transfer of pathogens. This includes after each use, when switching between different types of food (especially raw to ready-to-eat), or whenever contamination is suspected. Regular cleaning and sanitizing are critical to maintaining a safe food preparation environment.
