Food is an essential part of human life, providing us with the necessary nutrients to survive and thrive. However, food contamination is a serious issue that can lead to foodborne illnesses, which can have severe consequences for public health. Contamination can happen at any stage of food production, from the farm to the table. In this training module, we will define food contamination, discuss the main sources and pathways of contamination, and identify ways to detect contaminated food.
