Which of the following does NOT represent a type of chemical contamination?

Chemical contamination refers to the presence of harmful substances in food that can pose risks to health. This type of contamination can be categorized into various types based on intent and occurrence.

Intentional chemical contamination involves deliberate actions, such as the addition of toxins or substances to harm consumers. Accidental chemical contamination occurs without intent, often arising from improper handling or mixing of chemicals in food preparation.

Dealing with specific substances, metal contamination is another form of chemical contamination where metals, often from equipment or processing, inadvertently find their way into food.

Physical contamination, on the other hand, refers to the incorporation of foreign objects—like hair, plastic, or glass—into food, which poses a different type of risk and is not categorized under chemical contamination. Therefore, physical contamination does not represent a type of chemical contamination.
