- Chemicals that are approved sanitizers are iodine, quaternary ammonium, and chlorine. 8. The steps in the three-sink dishwashing method are scrape, wash, rinse, sanitize, and air dry. 9. Grease should not be poured down into the drain since it could solidify and clog the pipes. 10. In washing dishes by hand, we should work from lightly soiled to heavily soiled dishes.
The Correct Answer and Explanation is:
Here’s a breakdown of the statements you provided:
- Approved Sanitizers:
Iodine, quaternary ammonium compounds, and chlorine are commonly used sanitizers in food handling environments. These chemicals are effective at killing or inactivating microorganisms like bacteria and viruses, ensuring that surfaces, utensils, and equipment are safe to use. Sanitizers need to be used according to manufacturer guidelines for correct concentration and contact time to be effective. For example, chlorine is often used in concentrations ranging from 50 to 100 parts per million (ppm) in food safety applications, while iodine and quaternary ammonium are used at similar concentrations but have different antimicrobial profiles. - Three-Sink Dishwashing Method:
This method is used to ensure that dishes and utensils are thoroughly cleaned and sanitized. The steps are as follows:- Scrape: Remove food debris to prevent contamination of the wash water.
- Wash: Wash the dishes in hot soapy water to remove grease, oils, and food residues.
- Rinse: Rinse the dishes in clean, warm water to remove soap and dirt.
- Sanitize: Immerse the dishes in a sanitizing solution (such as chlorine or quaternary ammonium) to kill any remaining microorganisms.
- Air dry: Allow the dishes to dry naturally in the air to prevent re-contamination.
- Grease Disposal:
Grease should never be poured down the drain because it can solidify as it cools and cause blockages in plumbing. Over time, grease can build up in pipes and form what is called a “fatberg,” which can lead to serious plumbing issues and even environmental pollution if it makes its way into water systems. Grease should be collected in containers and disposed of properly according to local waste management guidelines. - Washing Dishes by Hand:
The correct approach to handwashing dishes is to start with lightly soiled items like glasses and cups, then progress to more heavily soiled items like pots and pans. This method ensures that you don’t contaminate the clean water or detergent with heavy food residues, making the washing process more efficient and sanitary. Starting with less soiled items also helps avoid the buildup of greasy residue in the wash water, which could affect the cleanliness of other dishes.
By following these guidelines, you can maintain a clean and safe kitchen environment, promoting both sanitation and the longevity of plumbing systems.
