What type of contamination is primarily caused by pathogens?

The correct answer is microbial contamination, which is primarily caused by pathogens such as bacteria, viruses, and parasites. These microorganisms can lead to foodborne illnesses when they are present in food or water. Pathogens can multiply in food that is stored at improper temperatures or left out for too long, making it essential for food handlers to follow safe food handling practices to minimize their risk.

Chemical contamination typically involves harmful substances like pesticides or cleaning agents reaching food, while physical contamination refers to foreign objects such as hair or glass being found in food. Allergenic contamination involves specific proteins that trigger allergic reactions in sensitive individuals, such as nuts or seafood. Understanding the types of contamination helps in implementing proper safety measures in food preparation and handling, with a strong focus on preventing microbial contamination to safeguard public health.
