In the past weeks, we have been learning about food. We have learnt about food substances and their uses in the body. We have also learnt about the importance of eating a balanced diet and what it is that makes up a balanced diet.

In this lesson,  we will be learning about contaminated foods and good eating habit.

Harmful foods

Food contamination refers to the presence of harmful chemicals and microorganisms in food, which can cause consumer illness. When food is contaminated it is said to be harmful.

There are various ways that food can become contaminated, they include:

  1. When food is not covered or properly covered, flies and other germs can get in.
  2. When food is not hygienically prepared. Example
  3. When it is prepared in a dirty environment.
  4. When it is prepared with impure water.
  5.  When food is prepared with a lot of chemicals and additives.
  6. When we talk too much while cooking,  our saliva might get into the food.
  7. Sneezing or coughing openly while cooking or eating.

All these will make food contaminated and thus renders it harmful and unsafe for consumption as it will likely affect our health.
