Analysis of Contamination Points of Milk through the Whole Value Chain Process and the Quality of Milk Products in the Dairy Industry

Product value chain is the full range of activities including production, processing, marketing and distribution a product takes until it gets to the consumer. In the dairy world, milk is a very vital food commodity for the growth and development of individuals; it’s a good source of calcium, vitamin B2, vitamin C and D and amino acids. Milk however, goes through a number of very important steps before it can be presented in the markets and stored to be purchased by the consumers. At every stage, there is milk contamination, starting from the health of the animal, the hygiene of the personnel, the safety levels of the animal’s feed, to more advanced levels of contamination such as during transportation, preservation, processing and at the shelves [1,2]. To ensure quality milk, it is necessary to understand the various causes and sources of milk contamination.
