Formaldehyde (as formalin solution) is primarily used for: 1. Preserving biological specimens in labs and medical institutions 2. Fixation of tissues for histological studies It is not permitted for food preservation because: • Highly toxic and carcinogenic (Class 1 carcinogen as per IARC) • Banned under FSSAI regulations for any food applications • Can cause severe health effects (respiratory distress, cancer) Key Regulatory Points: 1. FSSAI prohibits formaldehyde use in all food products (Fish/Meat/Milk) 2. Allowed only for non-food applications like laboratory preservation 3. Detection in food items constitutes adulteration punishable under PFA Act Why other options are wrong: • (A) & (C): Though sometimes illegally used by vendors, it's prohibited for fish/meat • (D): Never used in milk preservation - milk adulteration typically involves urea or detergents Safety Note: Food businesses using formaldehyde are subject to legal action under FSS Act, 2006. Consumers should report such adulteration to FSSAI.
