Food Adulteration
Reference: Park's Textbook of Preventive and Social Medicine, p. 755
Definition
According to K. Park, food adulteration is an age-old problem that consists of a large number of practices, including:
- Mixing - adding inferior or foreign substances to a food article
- Substitution - replacing a genuine ingredient with a cheaper or inferior one
- Concealing the quality - hiding defects or inferior nature of a food item
- Putting up decomposed foods for sale
- Misbranding or giving false labels
- Addition of toxicants
Under the Prevention of Food Adulteration (PFA) Act, 1954, any food that does not conform to the minimum prescribed standards set by the "Central Committee for Food Standards" is said to be adulterated. Similarly, any food containing food additives that are not permitted, or where permissible limits are exceeded, is also considered adulterated.
Disadvantages of Adulteration (as per Park)
Adulteration results in two key disadvantages for the consumer:
- The consumer pays more money for a foodstuff of lower quality (economic harm).
- Some forms of adulteration are injurious to health, even resulting in death.
Examples of Food Adulteration in India (Park's Table 37)
| Food Material | Common Adulterants |
|---|---|
| Cereals (wheat, rice) | Mud, grits, soapstone bits |
| Dals | Coal-tar dyes, khesari dal |
| Haldi (Turmeric) powder | Lead chromate powder |
| Dhania (Coriander) powder | Starch, cow dung or horse dung powder |
| Black pepper | Dried seeds of papaya |
| Chilli powder | Sawdust, brick powder |
| Tea dust/leaves | Blackgram husk, tamarind seeds powder, sawdust, used tea dust |
| Coffee powder | Date husk, tamarind husk, Chicory |
| Asafoetida (Hing) | Sand, grit, resins, gums |
| Mustard seeds | Seeds of prickly poppy (Argemone) |
| Edible oils | Mineral oils, argemone oil |
| Butter | Starch, animal fat |
| Ice-cream | Cellulose, starch, non-permitted colours |
| Sweetmeats | Non-permitted colours |
| Fresh green peas (packed) | Green dye |
| Milk | Extraction of fat, addition of starch and water |
| Ghee | Vanaspati |
Notable Examples with Health Consequences
Park specifically highlights two dangerous examples:
- Mustard oil adulterated with Argemone oil - causes Epidemic Dropsy, characterised by oedema, skin rashes, and cardiac failure.
- Edible oils adulterated with Tricresyl Phosphate (TCP) - causes paralysis and death.
Legal Framework: Prevention of Food Adulteration (PFA) Act, 1954
- Enacted by Indian Parliament in 1954; amended in 1964, 1976, and 1986 (made more stringent)
- Objective: To ensure pure and wholesome food and to protect consumers from fraudulent and deceptive trade practices
- Punishment:
- Minimum imprisonment of 6 months + fine of Rs. 1,000 for proven adulteration
- Up to life imprisonment + fine of not less than Rs. 5,000 for adulteration that may cause death or grievous hurt (u/s 320 IPC)
- Implementation is primarily by State Governments and local bodies; the Centre coordinates and monitors
- A chain of food laboratories and four regional appellate Central Food Laboratories (Kolkata, Mysore, Ghaziabad, Pune) have been established; their report is considered final
- In 1986, consumers and voluntary organizations were empowered to take food samples
Food Safety and Standards Act, 2006
Park also notes that the Food Safety and Standards Act (FSSA), 2006 was subsequently enacted to consolidate food laws and lay down science-based standards. The Food Safety and Standards Authority of India (FSSAI) was established in 2008 under this Act and is now implemented by all States/UTs.
Food Adulteration as a Social Evil (Park's View)
Park categorically states: "Food adulteration is a social evil." He identifies three groups responsible for perpetuating it:
- The public - due to lack of awareness and general disinterest
- The traders - driven by greed
- Food Inspectors - who exploit it for personal gain
He emphasizes that voluntary agencies and consumer guidance societies can play a vital role in curbing this evil.
