• When food or drinks are contaminated, food-borne diseases will occur. Food-borne diseases are also known as food poisoning.
• Food-borne diseases are caused by the presence of harmful bacteria in the contaminated food or drinks.
• Bacteria can cause infection directly in the intestine or release toxin (poisonous substances) in the bloodstream to cause infections.
• When a person suffers food-borne diseases, he or she will show one or more of the following symptoms:

1. fever
2. diarrhoea
3. vomiting
4. dehydration
5. stomach aches/cramps

The symptoms of food-borne diseases may take several hours or days to develop because bacteria need to reproduce to sufficient numbers before they can induce serious infections.

• Some of the measures to prevent food-borne diseases:

1. Keep the foodstuff in the refrigerators to slow down the reproduction of bacteria
2. Practice good personal hygiene
3. Wash the food before eating
