The generally accepted threshold for a healthy cow is up to 100,000 somatic cells/mL of milk. The generally accepted indicator of mastitis is 200,000 cells/mL of milk, with higher cell counts used as an indicator of the severity of infection.
What is a good somatic cell count?
Ideally, an individual cow cell count should be between 100,000 and 150,000. With a count below 50,000, there is some evidence that cows respond more slowly to infection.
Why is somatic cell count important?
Somatic cell counts are used to predict the health status of mammary glands. … Therefore, the risk of mastitis is significantly higher in herds with cell counts of several hundreds of thousands of cells per ml compared to herds with a bulk milk cell count of less than 200,000 or 100,000 cells/ml.
What does somatic cell count mean?
Somatic cell count (SCC) is the total number of cells per milliliter in milk. Primarily, SCC is composed of leukocytes, or white blood cells, that are produced by the cow’s immune system to fight an inflammation in the mammary gland, or mastitis.
How many somatic cells are allowed in milk?
The somatic cell count shall be not more than one million (1,000,000) cells per milliliter. The milk shall not contain drug residues.
How can I lower my somatic cell count?

Does milk have somatic cells?
Somatic cells are cells from the cow (predominantly white blood cells, otherwise known as leukocytes) that are normally present in milk. During most mastitis infections, the number of somatic cells present in the udder increases to help the cow fight the infection.
What causes high somatic cell count?
What Causes a High Somatic Cell Count? The somatic cell count of milk increases when a cow’s immune cells are released into the milk to fight against pathogenic bacteria like Staphylococcus aureus, which causes mastitis. Generally, the higher the somatic cell count, the worse the infection is.
How big is a somatic cell?
For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes. In humans, this is 23 unpaired chromosomes.
Are somatic cells pus?
Somatic Cell Counts in U.S Milk
Somatic cell count, according to the industry’s own National Mastitis Council, “reflects the levels of infection and resultant inflammation in the mammary gland of dairy cows,” but somatic cells are not synonymous with pus cells, as has sometimes been misleadingly suggested.
How do you test for somatic cell count?
A reliable direct method of measuring SCC is by using an automatic cell counter; either by using a portable cell counter at the farm, or by sending milk samples to a laboratory for measurement in, for example, a Fossomatic cell counter. The advantage with an automatic cell counter is that it is objective and accurate.
Does milk contain white blood cells?
There is not pus in your milk; just, normal white blood cells. While high levels of white blood cells can be unsafe, dairy farmers -and SO many others in the industry- work hard to ensure that the only milk reaching your dinner table is safe and quality tested.
What is Bactoscan milk?
The Bactoscan is a measurement of the number of bacteria present in milk (usually expressed as e.g. 20, meaning 20,000 bacteria/ml). High bacteria levels reduces the shelf life of liquid milk and may affect the ability to produce good quality cheese.
How do you calculate somatic cells in milk?
Somatic Cell Count, an indicator of milk quality
- An individual cow SCC of 100,000 or less indicates an ‘uninfected’ cow, where there are no significant production losses due to subclinical mastitis.
- A threshold SCC of 200,000 would determine whether a cow is infected with mastitis. …
- Cows infected with significant pathogens have an SCC of 300,000 or greater.
Why is milk bad for you?
Milk and other dairy products are the top source of saturated fat in the American diet, contributing to heart disease, type 2 diabetes, and Alzheimer’s disease. Studies have also linked dairy to an increased risk of breast, ovarian, and prostate cancers.
