There is no evidence that any particular cell count per se has any significant effect on human health. Normal Milk Mastitis is defined as an inflammation of the mammary gland. This is based on twice daily milking at regular intervals. The macrophages are involved in immune recognition and are the predominant cell type present in milk from uninfected quarters.
Lymphocytes are responsible for immune memory.
Milk from healthy, uninfected mammary glands has a white to white-yellow appearance and is free of flakes, clots, or other gross alterations in appearance. Such abnormalities are indicators of milk that is unsuitable for human consumption. The vast majority of these abnormalities appear as a result of bacterial infection of the mammary gland. In general, the more severe the infection, the greater the abnormal appearance of the secretion from the infected quarter. Implications for Cow, Herd, and Regulatory SCC Composite milk is the result of the commingling of milk from a cow s four independent mammary quarters.
