Lesson 5 explains why cleanliness is essential in commercial food service, linking sick employees, unsafe hygiene, and contaminated surfaces to foodborne-disease outbreaks. It defines key sanitation terms, chlorine and sanitizer concepts, and clarifies proper cleaning before sanitizing. The lesson includes activities to teach effective hand-washing with UV light and germ-simulating products, demonstrates correct glove use, and covers safe handling of garbage, waste, and bodily fluids. It also describes restrictions for workers with infected wounds.

GOAL OBJECTIVES TEACHER BACKGROUND INFORMATION LESSON 5 Clean: Do You Want to Eliminate a Million…Bacteria? To understand the importance of cleanliness, healthy workers, and proper handling of garbage, waste, and bodily fluids in commercial food service. • To understand the need for equipment and personal cleanliness when preparing food for others. • To demonstrate proper hand-washing techniques. • To identify times when hands should be washed when preparing food for others. • To demonstrate proper use of gloves. • To make an approved sanitizing solution and to know when and how to use it. • To list proper handling procedures for garbage, waste products, and bodily fluids. • To recognize when sick employees should not handle food. Lesson 5 covers 1. Personal hygiene, especially proper hand washing 2. Food-contact surface cleaning and sanitizing 3. Correct garbage/waste/bodily fluid (vomit, blood, excrement) handling 4. Restrictions and exclusions for sick employees Approximate time to teach lesson: 25–50 min. Definitions chlorine—One of the chemical elements that forms hypochlorite. Hypochlorites are used in sanitizing solutions. Chlorine compounds deodorize, control a wide range of microorganisms, and are economical to use. They are colorless and nontoxic to humans when used in the recommended concentrations. Chlorine bleach should NEVER be mixed with other chemicals, especially ammonia-based cleaners, unless specifically stated on the chemical label. clean—Free of visible soil, including food particles and dirt. Refers to outward appearance. cleaner—Soap or detergent that loosens soil and food so they can be rinsed away. food-contact surface—Any surface of equipment, utensils, containers, and wrappings that come in direct contact with food. ppm—Parts per million. A measurement used to define sanitizer concentrations. One ppm = 1 mg per liter = mg/L. sanitary—Clean and free of harmful microorganisms and other contaminants. To be effective, sanitizing must follow a thorough cleaning. 72 READY, SET FOOD SAFE ● LESSON 5 sanitation—The act of reducing microbial organisms to a safe level on cleaned food-contact surfaces. sanitizer—An approved substance to use when sanitizing food service equipment and utensils. sterile—The absence of all living microorganisms. ware washing—The process of cleaning and sanitizing equipment, utensils, pots, pans, and dishes. Food Safety Implications Sick employees, poor hygienic practices, and contaminated equipment are major causes of foodborne-disease outbreaks. Therefore, maintaining a clean and sanitary facility and clean employees can greatly enhance the safety of food prepared in a food establishment. Hand washing is recognized by the Centers for Disease Control and Prevention (CDC) as the most important means of preventing germs from spreading. People can carry disease-causing microorganisms and pass them onto others through food. In some cases, they don’t show any signs of illness themselves. For example, people can infect food with Hepatitis A for 15 to 50 days before any symptoms of the illness emerge. A major key to controlling foodborne illness in commercial food service is clean hands and the use of frequently changed, single-use, disposable gloves when handling food. Workers often handle both raw and cooked food. Washing hands and changing gloves is required when changing tasks from handling raw to handling cooked or readyto-eat food to prevent harmful bacteria from contaminating foods. Hand-Washing Activity A UV (black) light and GlitterBug Potion or Glo Germ Gel (fluorescing hand lotions) are useful in demonstrating how well students wash their hands. Students put the lotion on their hands, rub it in well, and inspect their hands for the presence of germs under a black light in a darkened room. The GlitterBug Potion or Glo Germ Gel, which simulates germs, is invisible under regular light but glows under a black ligh

FAQs

Why is cleanliness critical in commercial food service?

Sick employees, poor hygiene, and contaminated equipment drive foodborne-disease outbreaks. Clean facilities and clean employees reduce the risk of germs spreading through food.

How do the lesson’s hand-washing activities show whether students wash effectively?

Students apply a fluorescent lotion or gel, then inspect hands under a black light to find germ-simulating residue. They wash thoroughly for about 20 seconds with soap and warm water and check again under the black light.

When must gloves be used and changed?

Bare-hand contact with ready-to-eat foods is prohibited. Food workers must use barriers or single-use gloves, and gloves must be changed whenever hand washing is required.
