Importance of Consumer Health and Measures to Protect Consumer Health

The consumer society of urban areas and developed parts of the world has been facing many problems along with its development. Protection of Consumer Health is legal provision of punishment on production and distribution of goods and services which have adverse affect and harmful to consumer health. This note provide us the information about importance of consumer health and measures for protection of consumer health.

Summary

The consumer society of urban areas and developed parts of the world has been facing many problems along with its development. Protection of Consumer Health is legal provision of punishment on production and distribution of goods and services which have adverse affect and harmful to consumer health. This note provide us the information about importance of consumer health and measures for protection of consumer health.

  • It gives the knowledge of the existing laws and protection of their consumer rights.
  • Laws for the protection of consumer health was first introduced in the USA on March 15, 1963.
  • There is legal provision of punishment on production and distribution of goods and services which have adverse affect and harmful to consumer health.

Importance of Consumer Health and Measures to Protect Consumer Health

Importance of Consumer Health and Measures to Protect Consumer Health

The process of depending on the produced goods and services is increasing in this world along with the development of human civilization. Now, everything is produced in industries and made available in the market. People are largely dependent on the goods and products available in the market. Therefore, the societies especially of urban areas and developed countries have now become consumer society. If we look at the condition of rural and some primitive societies, people produce almost all the goods required for them and still practice barter system to fulfill their additional requirement. They do not totally depend on the goods and services of the market whereas the situation of urban and developed society is different.

The consumer society of urban areas and developed parts of the world has been facing many problems along with its development. Some of these problems and evils are unemployment, individualistic feelings, and unnatural competition in work performance, bribery, smuggling, etc. These all problems have directly made adverse impacts on consumer health because low quality, adultery and harmful goods are produced and sold in the market. Some people, anyhow, want to earn money and become rich overnight. When they involve in business, they produces low quality and even mix harmful things in good. This is in increasing trend in Nepal due to lack of proper supervision from the government and consumers. If the consumers are not aware, they cannot select right goods and become the victim of adulteration and wrong practices. Therefore, it is a high time for all of us to make consumers aware of the quality of goods that they consume and it is consume health education, which inspires the consumers to be more conscious and united to protect their health.

The importance of consumer health are given below:
  1. It makes people aware of the quality of goods that they purchase.
  2. It helps people to take right service on right time.
  3. It gives the knowledge of the existing laws and protection of their consumer rights.
  4. It helps to encourage consumer to be united and raise collective voice against the practice of adulteration and quackery.

Measure to protect Consumer Health

Consumers should be aware about their health. They should be organized to protest the fraudulent activities of industries in providing harmful goods. Several methods can be adopted for the protection of consumer health. Some of the methods are described below:

Use of Goods and Services:

  • We must be careful while buying goods. We must notice the name of the company, manufacturing date, expiring date etc. Open goods should not be purchased as far as possible. As quality goods, quality health services is equally important. We should not do negligence while choosing doctors. We should be aware of quack doctors in order to protect our health.
  • Storing: Nowadays producers do not bring all their goods in the market as soon as they manufacture or grow them. They keep the food in some safe places. It is known as storing. Storing foods from long time may rot away or may moth-eaten. Using such foods is injurious to health.

Legal Provision On Consumer Health

Laws for the protection of consumer health was first introduced in the USA on March 15, 1963.In Nepal some legal protection of consumer health is implemented.
Consumer Protection Act, 2054 B.S.
Government has brought in force the Consumer Protection Act, 2054 B.S. It has provided the consumers the following rights:
  • Right to be safe from selling harmful goods and services which have adverse effect on body.
  • Right to be informed about the price, quality, quantity etc of the manufacturing goods.
  • Right to choose the best alternatives for competitive price.
  • Right to appeal and compensation for exploitation and loss of consumers from the inappropriate activities.
  • Right to get Consumer Education.
There is legal provision of punishment on production and distribution of goods and services which have adverse affect and harmful to consumer health. The government has released an inspection officer's guidelines 2058 to conserve the consumer health and right. It has mentioned the duties of inspection officers.
  • Help to conserve and promote consumer right.
  • Help to supply and control of low quality foods by regular market monitoring.
  • Make the shopkeeper to put price list clearly.
  • Increase awareness on consumer health.
Essential Goods and Controlling Act 2017 B.S.
This was the first law in Nepal for the protection of the consumers. It explained the price, distribution system, and punishment for deliberate creation of artificial security.
Food Act, 2023 B.S.
It explained the assessment of the quality food-stuff and medicine along with their sale and distribution system.
Standard Measurement Act, 2025 B.S.
This act was passed to bring unifirmity in measurement system under the Mint Department of Nepal Rastra Bank.
Black- marketing and other Social Offence Punishment Act, 2032
Legal action can be taken against black marketing, artificial shortage, adulteration and social offences, according to this act.
Drug Act, 2035 B.S.
It deals with the production and distribution of medicine.
NepalStandardAct, 2037 B.S.
Itconcerned with the examination of products in Nepal and providing quality mark on products.
