Disinfecting kills most germs on surfaces and objects. Disinfecting is done with stronger bleach solutions or chemicals. Clean surfaces before you disinfect them.
Disinfection describes a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects (Tables 1 and 2). In health-care settings, objects usually are disinfected by liquid chemicals or wet pasteurization.
Cleaning removes debris, dust, and dirt from surfaces, but it doesn't necessarily kill germs. Sanitizing is the process of removing germs either by cleaning or by disinfecting surfaces. Disinfecting refers specifically to killing germs through the use of chemicals.
The Correct Answer is Option 1 i.e Sterilization. Sterilization: The process of killing the pathogenic bacteria of waterborne diseases to make it safe for hospital use is known as Sterilization.
Sterilization is defined as a process that eliminates all forms of microorganisms, spores, and viruses through physical or chemical means.
Disinfecting kills most germs on surfaces and objects. Disinfecting is done with stronger bleach solutions or chemicals. Clean surfaces before you disinfect them.
Sterilisation involves the use of high levels of heat, chemicals or other procedures to remove all microorganisms including bacteria, viruses, spores and fungi, from surfaces or objects. Sterilising is rarely required or performed outside of healthcare setting such as hospital operating rooms.
According to World Health Organization, temperatures of at least 140 degrees Fahrenheit (60 degrees Celsius) are enough to kill most viruses. Boiling water can kill off the bacteria on food and running your dishwasher is enough to sterilize your dishes from germs.
Macrophages and neutrophils (phagocytes) are the front-line defenders in your body's immune system. They seek out, ingest, and destroy pathogens and other debris through a process called phagocytosis.
Disinfection describes the use of a chemical or physical process to inactivate or eliminate microbial organisms on inanimate objects or surfaces. These processes destroy or irreversibly inactive most pathogens, but are generally less effective against bacterial endospores.
GUIDELINES FOR CLEANING AND DISINFECTION
Cover spills with absorbent material (e.g., paper towels), then pour disinfectant on to saturate the area, and allow bleach to soak into spills for at least 30 minutes before cleaning to allow it to kill any virus or other infectious agents that may be present.
The immune system uses white blood cells and antibodies to identify and eliminate organisms that get through the body's natural barriers. (See also Overview of Infectious Disease.)
The major types of sanitizers are heat, radiation, and chemicals. Chemicals are more practical than heat and radiation for food production facilities.
The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes. Phagocytes eventually die. Pus is formed from a collection of dead tissue, dead bacteria, and live and dead phagocytes.
Decontamination is a combination of processes that removes or destroys contamination so that infectious agents or other contaminants cannot reach a susceptible site in sufficient quantities to initiate infection, or other harmful response. The various levels of decontamination are described below.
Disinfection is defined as a procedure, the result of which is transient and that eliminates or kills microorganisms and/or deactivates undesirable viruses that are carried by inert contaminated environments.
Decontamination. Decontamination is a process that removes, inactivates or destroys pathogens so that an item is unable to transmit infection and is safe to use. It always involves cleaning and is followed by disinfection and/or sterilization.
There are two types of leukocytes: phagocytes and lymphocytes. Phagocytes engulf the intruders, break them down and chew them up. Lymphocytes are further broken down into two more types. The B lymphocytes (or B-cells) create antibodies and alert the T lymphocytes (or T-cells) to kill the pathogens.
Hydrogen peroxide.
Hydrogen peroxide (H2O2) is a widely used biocide for disinfection, sterilization, and antisepsis.
You have to remember that cleaning and disinfecting aren't the same thing, and know how, what -- and when -- to do both. “Cleaning removes dirt and impurities from surfaces,” says Khanya Brann, a spokesperson for the Environmental Protection Agency (EPA). “Disinfecting kills germs.”
Explanation: The process that reduces pathogens on a food-contact surface to a safe level is known as sanitizing. Sanitization is a protocol that reduces the microbial load on inanimate surfaces to levels deemed safe for public health.
The top level in this hierarchy of decontamination is sterilization, which kills all microbes and is required for all items coming into contact with sterile body cavities.
If you need to kill germs on household surfaces, use a disinfectant such as hydrogen peroxide (3%) or diluted household bleach. Hydrogen peroxide (3%) can be applied to surfaces.
