खाद्य सुरक्षा: विषाक्तता और जोखिम
This Class 12 Home Science topic, from the chapter Food Quality and Food Safety, explains how food can become unsafe through natural toxins, chemical contaminants, harmful microorganisms, allergens, and unsafe handling practices. Students learn to distinguish a food hazard from toxicity, understand how contamination affects health, identify common sources of risk during processing, storage, and preparation, and apply basic principles of prevention, hygiene, safe storage, and responsible food selection.
Correct answer: B. To know safety and usable period
Explanation: The expiry or use-by date tells consumers the period during which a packaged food is expected to remain suitable and safe when stored as directed. Eating food beyond that date can increase safety risks, although appearance alone cannot prove safety. Labels, storage instructions, and package condition should all be checked.
