What are the main types of food contaminants?

• A. Viral, bacterial, and chemical
• B. Biological, chemical, and physical
• C. Organic, inorganic, and artificial
• D. Surfactant, emulsion, and suspension

Answer: (B)

The main types of food contaminants are classified into biological, chemical, and physical categories. Biological contaminants include pathogens such as bacteria, viruses, and mold, which can be harmful to health when ingested. Chemical contaminants encompass substances that may unintentionally enter food, such as pesticides, heavy metals, and food additives that could pose health risks if consumed inappropriately.

Physical contaminants are foreign objects that may inadvertently be present in food, such as pieces of glass, metal, or plastic, which can cause choking or injury when consumed. This comprehensive approach to categorization helps food safety professionals identify the potential risks associated with food and implement appropriate controls to minimize contamination during processing, handling, and preparation.

Other answer choices either focus on specific types of contaminants that fall under the broader categories or include terms that are not directly related to food safety, further validating that biological, chemical, and physical contaminants are the most relevant and recognized classifications in food safety practices.
