Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -14 Questions and Answers

-Format: Multiple-choice / Flashcard

Question 1: Abrasive cleaners

Answer:

Cleaners containing scouring agents used to scrub off hard to remove dirt. They may scratch some surfaces

Question 2: Iodine sanitizer

Answer:

Iodine based compounds that are less active than hypochlorites but are effective sanitizers and disinfectants. Iodophors attach to the sulfurs of proteins such as cysteine, causing inactivation and cell wall damage. Carriers with iodophor solutions allow a sustained-release effect, resulting in continuous microbial mortality.

Question 3: Detergents

Answer:

Cleaners designed to penetrate and soften dirt to help remove it from a surface.

Question 4: Water activity

Answer:

Amount of moisture available in food for microorganisms to grow (FAT TOM). Water activity is measured on a scale from 0.0 to 1.0 with water itself having a water activity of 1.0. TCS food typically has a water activity value of 0.85 or highe

Question 5: Sanitizing

Answer:

Process of REDUCING the number of microorganisms on a clean surface to safe levels. Food service operations generally use sanitizers instead of disinfectants on food contact surfaces since the total kill characteristics of disinfectants can potentially also cause harm to human life

Question 6: Cleaning

Answer:

Process of removing food and other types of dirt from a surface, such as a countertop or plate

Question 7: Degreasers

Answer:

Alkaline detergents. Often called de-greasers, that contain a grease dissolving agent

Question 8: Concentration

Answer:

The amount of sanitizer to water measured in parts per million (ppm). The concentration of sanitizer affects the effectiveness of the sanitizer solution

Question 9: Water hardness

Answer:

The amount of minerals in water. Water hardness affects how well a sanitizer works. Generally, the harder the water (the more minerals the water has), the harder the sanitizer needs to work and is required in the concentration of sanitizer and water.

Question 10: Chlorine sanitizer

Answer:

A solution containing 3-8% sodium hypochlorite and 0.01-0.05% sodium hydroxide (bleach) added to water at a usual ratio of 1 teaspoon to 1 gallon of water in order to reduce microorganisms of public health importance to levels considered safe, based on established parameters, without adversely affecting either the quality of the product or its safety

Question 11: Disinfecting

Answer:

Process of DESTROYING the number of microorganisms on a clean surface to safe levels.

Question 12: Material Safety Data Sheets (MSDS)

Answer:

): (Name being changed to Safety Data Sheets (SDS) to comply with global standards.) Sheets supplied by the chemical manufacturer listing the chemical and its composition, its common names, its potential physical and health hazards, first aid information, safe handling practices, long term effects of using the chemical and other important and pertinent information. All commercial establishments are required by federal OSHA laws to have and have readily accessible (without asking) Material Safety Data Sheets (or SDS) for the staff to access at any time. MSDS (or SDS) are required for every chemical used or stored in the establishment from glass cleaner, detergents to the chemicals used for exterminating

Question 13: Delimers

Answer:

Used on mineral deposits and other soils that alkaline cleaners cannot remove

Question 14: Quaternary sanitizer

Answer:

Also called quats. A quaternary based sanitized reflecting fairly complex chemical composition in which nitrogen is bound to four organic groups. The positively charged cations in the compounds bind with the acidic phospholipids in the microbial cell wall. This action blocks the uptake of nutrients into the microbial cell and prevents the discharge of waste. In general, quats are effective against a wide range of microbes, although the spore phase is unaffected.
