Sediment in milk is generally due to poor pre-milking hygiene procedures that allow soil and other
materials to enter the milking stream. Proper environmental conditions for cow cleanliness are important to reduce
soil on animals so that pre-milking hygiene procedures can be effective. Sediment in milk is measured by filtering
the milk through a fine filter and visually examining it and comparing to a standard. High sediment levels in milk
are associated with filth and the potential for bacterial contaminants that can influence quality.
