A somatic cell count (SCC) is a cell count of somatic cells in a fluid specimen, usually milk. In dairying, the SCC is an indicator of the quality of milk—specifically, its low likeliness to contain harmful bacteria, and thus its high food safety. White blood cells (leukocytes) constitute
After allowing to dry, it is colored and performs counting. For this, the average of existing cells is performed in the field of the microscope, dividing total somatic cells from microscopic factor (MF) which corresponds to the number of fields in one inch, i.e. 100 mm, obtaining in this way the number of somatic cells per milliliter of milk.

The California mastitis test (CMT) is a simple cow-side indicator of the somatic cell count of milk. It operates by disrupting the cell membrane of any cells present in the milk sample, allowing the DNA in those cells to react with the test reagent, forming a gel. [1] It provides a useful technique for detecting subclinical cases of mastitis.
The milk protein continues to undergo further deterioration during processing and storage. [9] Milk from cows with mastitis also has a higher somatic cell count. [10] Generally speaking, the higher the somatic cell count, the lower the milk quality. It also has a high microbial count. This reduces its yield. [11]

The somatic cell count shall be not more than one million (1,000,000) cfu cells per milliliter. The milk shall not contain drug residues. Milk not meeting these standards shall be designated as undergrade. Undergrade milk may not be sold for human consumption or processing into products for human consumption.
As reported by the USDA, the US pattern for milk BTSCC declined steadily from 316,000 cells per mL of milk in 2001 to 224,000 cells/mL in 2010 and 206,000 cells/mL in 2011 (USDA, 2013). Mammary health in the animals themselves has improved over this time period as well as the overall health of the dairy herd in general.
