Milk hygiene practice in India
Rubyta Chanam *
Generally animals are milked at least twice a day worldwide including India, which can influence hygiene quality of milk considerably.
Tropical climate, inadequate cooling facilities, wide spread adulteration, lack of quality consciousness and small scale scattered production are the prevailing conditions in India. In India milk production and distribution are currently being followed in an unorganized way.
However, in a modular system, which is carried out in a highly organized way like ANAND pattern co-operative system operating in Gujarat, the individual milk producer supplies the milk within 1-3 hours of production to a village level society.
This is transported twice-a-day in cans within 3-5 hours to the district level dairy plant under ambient conditions.
In an Indian situation, where the dairy plant is far off, the milk from village society goes to a chilling centre, cooled below 50C and then transported to the district level dairy plant.
Here it is pasteurized and supplied to the consumer. In developed countries, it is a common practice to cool the milk immediately in the farm, and the same is collected by the dairy plants every day or alternate day or twice a week. This practice requires cold storage of milk at collection centres for 2-3 days before it is processed.
In western countries, the problem of milk borne diseases have been solved completely by enforcing strict laws.
Animals are periodically tested for contagious diseases and all measures are taken to produce milk free from pathogens.
Even though these conditions are not strictly followed in our country, the habit of boiling in milk invariably before consumption by the consumer has probably saved them from serious milk borne infections, and Milk Products Order (MMPO). In India, in 1991 as a part of the economic reforms, the dairy sector was delicensed. This effectively opened the industry to private entrepreneurs. The Government of India promulgated the Milk and Milk Products Order (MMPO) in June 1992.
MMPO prescribes certain provisions for the orderly development of the dairy industry. One of the key features include that all plants handling between 10000 and 75000 litres/day or producing milk products containing more than 500 and 3750 tonnes of milk solids per year are required to be registered by the State authorities, while those processing over 75000 litres/day or more than 3750 tonnes per year of milk solids require registration with the central government.
The premise in which milk or any milk product is being handled, processed or manufactured, stored or distributed, by the holder of the registration certificate, and the person handling them shall conform to the sanitary requirement and standards.
o The premises shall be clean, adequately illuminated and ventilated, properly white washed or painted. There shall be proper and adequate arrangements for disinfection and deodorization. There should preferably be space around it on all sides.
