    Food spoilage and food poisoning are two distinct terms that should be treated differently

    However both affect the safety of food when consumed. Food spoilage is a natural process, sometimes enhanced by microbial or chemical contaminants, resulting in inedible food that has deteriorated past a point for safe human consumption. The resulting contaminants, microorganisms or pathogens, are a cause of food poisoning. 

     



  • Factors influencing growth of food spoiling micro-organisms

    There are several factors which influence the growth of food spoiling microorganisms. The external environment has a huge influence on their ability to grow. The humidity level in a food storage area plays its part, with high humidity areas encouraging rapid bacterial growth due to the presence of large amounts of moisture in the air. The temperature of a storage area also affects micro-organism growth, where growth is well served in warm conditions.

    Micro organisms tend to be attracted to food that is high in energy sources, rich in nutrients and contains moisture. The amount of water content in food will influence the rate at which micro-organisms can grow on the food. They also tend to thrive on foods with a lower acidity.

    • Diarrhoea
    • Abdominal pains and cramps
    • A fever or chill
    • Extreme vomiting containing blood
    • Stools containing blood
    • An inability to keep any type of liquid 'down' (in a stomach)
    • Excessive thirst, sweating, little or no urination, drowsiness
    • Blurred vision and giddiness
    • High body temperature

  • Treating food poisoning

    One of the major side effects of food poisoning is dehydration (loss of fluids through vomiting, diarrhoea) so it is vitally important to keep hydrated. It is also advised to avoid solid food until vomiting ceases and only then ingest light and bland foods. It is recommended that greasy or oily foods are avoided along with dairy and caffeinated drinks. In an effort to replace lost liquids and minerals, oral rehydration solutions can be taken during longer periods of diarrhoea and vomiting (+24 hours). However, self medication is highly discouraged. Taking anti-diarrheal or anti-nausea medication for prolonged periods of time is not recommended.

    Food poisoning can be fatal so it is advised that medical attention be sought immediately; especially when symptoms persist or get worse and if the individual is vulnerable (very young, very old). If in doubt, contact a qualified doctor immediately.
