Food borne diseases often referred to as FBD, are defined by the World Health Organization as “diseases of infectious or toxic nature caused by, or thought to be caused by the consumption of food or water”. Food poisoning occurs when we swallow liquids or ingest foods, contaminated by certain bacteria, parasites, viruses or toxins from germs. The main culprits of FBD’s are disease causing pathogens that contaminate the food, poisonous chemicals or harmful substances present in the food and the most common bacteria of FBD are Salmonella, Staphylococcus, E-Coli and botulism.
Food poisoning is a fairly common problem, easily managed if basic precautionary measures are in place, but a small lapse can rapidly escalate out of control, even become life threatening. Food poisoning most often has been found to be a result of laxity in basic hygiene. Contaminants find their way into the food in different ways:
- Person-to-person transmission of salmonella occurs when an infected person's feces, from unwashed hands, contaminates food during preparation or storage or infects a person directly through hand shakes etc.
- Eggs contaminated through feed or passed from one bird to the next.
- During preservation or preparation of poultry, fish and meat, contaminated by machinery used to cut and package foods.
- Contaminated water used for growing, cleaning and storing the food. (manure or human waste)
