What is a Food borne Illness?
Food borne illness is an infection or irritation of the gastrointestinal (GI) tract caused by food or beverages that contain harmful bacteria, parasites, fungi, or viruses.
- Food borne illnesses are linked to the deaths of an estimated 2 million people annually.
- Mostly children – and most of these illnesses, including food borne illness, are attributed to contaminated food or water
How do food borne bacteria grow?
- Food borne bacteria are often naturally present in food, and in the right conditions, a single bacterium can grow into more than two million bacteria in just seven hours.
- These bacteria multiply rapidly on foods with lots of protein or carbohydrates when the food temperature is between 5 °C to 60 °C which is often known as the ‘food danger zone’.
Which food is preferred by food borne bacteria?
Bacteria grow and multiply on some types of food more easily than on others. The types of foods which bacteria prefer include:
- Dairy products.
- Cooked rice.
- Prepared fruit.
Who are at risk?
Some people are at a higher risk for developing food borne illness. These include:
- Pregnant women.
- Young children.
