The term "hygiene" refers to the maintenance of health and healthy living. Proper washing of our hands, a form of hygiene, is the most effective overall way to prevent the spread of infectious disease.
The purpose of food and cooking hygiene is to prevent food contamination, the transmission of disease, and to prevent food poisoning. Food and cooking hygiene protocols specify safe ways to handle and prepare food, and safe methods of serving and eating it.
Such protocols include:
• Washing of hands thoroughly before touching any food.
• Proper disposal of uneaten food and packaging.
• Washing of hands after touching uncooked food when preparing meals.
• Proper bandaging and dressing of injuries.
• Use of protective clothing, such as gloves and masks
• Sterilisation of instruments used in surgical procedures.
• Safe disposal of medical waste.
Excessive hygiene practices may cause allergic diseases. Some parts of the body, like the ear canal or vagina should not be interfered with but left to the body's cleaning systems. Excessive application of soaps, creams, and ointments can have a bad effect on the body's natural processes. Soaps and ointments can deplete the skin of natural protective oils, and some substances like solvents can be absorbed and, even in trace amounts, disturb natural hormonal balances.
