In Class 12 Home Science, this topic from Food Quality and Food Safety helps students understand the three major types of hazards that can affect food. They learn how physical hazards such as glass or metal fragments, chemical hazards such as pesticide residues or cleaning agents, and biological hazards such as bacteria, viruses, and parasites enter food and threaten health. The topic also explains common sources of contamination, safe handling and storage practices, personal hygiene, and basic measures for preventing or controlling these risks.

Food contamination means that harmful biological agents such as bacteria, viruses and parasites, chemical substances such as pesticides or cleaning residues, or physical objects enter food.
