Clean Milk production

General Information

Milk is the main product from a dairy enterprise, produced basically as food for human consumption. A dairy farmer must therefore aim at maximising on milk output from his/her dairy herd. At the same time the farmer must ensure that milk is produced in clean and hygienic conditions so that it is fit for human consumption.

From public’s health point of view, milk is a very good media for bacterial and other micro-organisms development. As such, disease hazard in public can easily be predisposed by infected milk during production, handling and marketing.

As business, milk which is not available for human and economical use is a loss to the producing farmer. The following reasons will justify why ever farmer should strive to produce clean and wholesome milk:

  • Farmers are not paid for the milk which is rejected in the market. As such, they lose in labour and other inputs used in producing this milk.
  • Dirty milk will have keeping period and if it cannot be used quickly, then it is thrown away and lost as useless food.
  • Rejected milk due to dirt means a total loss as a source of food for the nation. The nation will therefore spend money to import such food and that money spent could have been used for other development projects.
