Verified step by step guidance1
Understand the types of contamination that can affect food: Chemical contamination involves harmful chemicals, Radiological contamination involves radioactive substances, Physical contamination involves foreign objects like glass or metal, and Biological contamination involves living organisms such as bacteria, fungi, or viruses.
Identify the key phrase in the question: 'contamination of food by other living organisms such as bacteria, fungi, or viruses.' This indicates the contamination is caused by living entities.
Recall that bacteria, fungi, and viruses are all biological agents, meaning they are living or once-living organisms that can cause contamination.
