FDA (21CFR 131.110) describes milk as "the lacteal secretion, practically free from colostrums, obtained by the complete milking of one or more healthy cows." Milk obtained aseptically from the udders of healthy cows contains a very low number (<1,000/ml) of bacteria. However, since milk is an excellent growth media, microorganisms introduced during production and handling may multiply rapidly under conditions of marginal refrigeration(slow cooling and storage between 40)
