The unique composition of milk (water and other nutrients) makes it a highly perishable commodity. It is an ideal medium for growth of microorganisms and, therefore, highly susceptible to microbial spoilage. If not produced and handled in a proper hygienic manner, various types of spoilage and disease-producing organisms can grow in milk and milk products and make these unfit/unsafe for human consumption. Therefore, it is very important that milk particularly after production is handled in a hygienic manner and processed properly so that it not only retains its quality and but also remains good for a longer period before consumption. Consumers have a right to good quality and safe milk and milk products.
