Adulteration of milk

  • F. Harding


When consumers buy milk they have a right to assume that it will be pure and unadulterated. Hence, there is an obligation on the dairy industry to provide adequate quality control systems. Milk may be adulterated on purpose in order to defraud—fortunately a rare occurrence—or accidentally during production or processing. There are many potential adulterants:
  1. (a)

    Extraneous water

  2. (b)

    Detergents/sterilants accidentally finding acess to milk during production

  3. (c)

    Teat dips, udder salves, etc.

  4. (d)

    Neutraliser used to mask developed acidity

  5. (e)

    Skim-milk powder used to elevate milk solids

  6. (f)

    Salt or sugar used to mask extraneous water or to elevate total solids

  7. (g)

    Preservatives such as formalin, hydrogen peroxide, hypochlorite, etc. used to mask poor hygienic quality

  8. (h)

    Foreign fats
