explain why cleanliness in food, water and personal hygiene practices assist in the control of disease
- There are huge numbers of disease causing organisms. Most of them are microscopic and can enter the body through any body opening. The intake of food and water provide an easy way for micro-organisms to enter our bodies. Therefore, minimising the number of such organisms in our food and water reduces the risk of infection. Good personal hygiene ensures that body openings, including broken skin, are clean, so that the number of micro-organisms that might gain entry to our bodies is kept low. Since we cannot see individual micro-organisms we take precautions that we know will help to protect us. Examples of precautions include, washing hands after going to the toilet, cleaning wounds, boiling water and water treatment of water that doesn’t come from a known safe source to make sure untreated sewage does not get into food or water supplies.
