Early Somatic Cell Counting
First Observations in Milk
Researchers began to study the contents of milk in the early 20th century. They noticed that milk contained more than just fat, protein, and water. Scientists observed cells under the microscope and realized that these cells could reveal important information about the health of dairy cows. At first, most laboratories focused on counting bacteria in milk samples. They did not use somatic cell counting as a routine practice because the technology was limited and the process took a lot of time. Early studies showed that high cell counts often appeared in milk from cows with udder infections. This discovery encouraged more research into the role of cells in milk quality.
Note: Early scientists relied on simple tools and careful observation. Their work laid the foundation for modern milk testing.
Direct Microscopic Count
The direct microscopic count became one of the first methods for measuring cells in milk samples. Technicians placed a drop of milk on a glass slide and stained it with methylene blue. This dye helped them see the cells more clearly under the microscope. They counted the cells in several fields and calculated the average number. The process required patience and skill. Methylene blue staining played a key role because it made direct microscopic somatic cell count stand out from other particles in milk. Although this method improved accuracy, it remained slow and labor-intensive. Most dairy laboratories did not use it for routine testing. The need for faster and more reliable techniques led to new developments in somatic cell counting.
- Early methods:
- Used basic microscopes.
- Relied on manual counting.
- Applied methylene blue staining for better visibility.
These early efforts helped scientists understand the link between cell counts and milk quality. They set the stage for future advances in milk testing technology.
Advancements in Somatic Cell Count Methods
Fossomatic Technology
The introduction of Fossomatic technology marked a turning point in somatic cell count analysis. Researchers developed this automated system to address the limitations of manual microscopic methods. Fossomatic devices use flow cytometry, which allows rapid analysis of milk samples. The machine passes milk through a laser beam, and sensors detect somatic cells based on their light scattering properties. This process provides accurate somatic cell count results within minutes.
Dairy laboratories adopted Fossomatic technology because it improved efficiency and reduced human error. Technicians no longer needed to spend hours counting cells under a microscope. The system enabled high-throughput analysis, which helped producers monitor milk quality more effectively. Fossomatic technology also standardized somatic cell count testing, making results more reliable across different laboratories.
Fossomatic technology transformed milk analysis by automating cell detection and reducing variability in results.
Somatic Cell Count Tester

The device combines advanced imaging, nanoparticle-mediated detection, and sophisticated algorithms to deliver fast and precise results. The shift to electronic methods began with the need for real-time analysis of milk samples. Automated testers use image-processing algorithms to analyze thousands of cells in seconds. This approach increases accuracy and repeatability in somatic cell count analysis.
Modern testers often include AVM modules, which facilitate visualization and retention of nanoparticle-cell aggregates. This innovation enables rapid, on-site visualization and real-time results for milk samples. Nanoparticle-mediated detection eliminates the need for fluorescent labeling, streamlining the workflow and overcoming limitations of conventional methods. The integration of these technologies allows dairy producers to perform cmt analysis directly on the farm, reducing delays and improving decision-making.

Impact of Somatic Cell Counts
Milk Quality
Somatic cell counting has transformed how dairy scientists measure milk quality. High somatic cell counts in milk often signal udder infection or inflammation in cows. When the mammary gland faces infection, the number of somatic cells rises. This increase affects both the taste and safety of milk. Producers use the california mastitis test to detect elevated scc levels and identify infected milk before it enters the supply chain. The table below shows how somatic cell count and total plate count (TPC) serve as indicators for milk quality and safety:
| Indicator | Description | Impact on Milk Quality and Safety |
|---|---|---|
| SCC | Measures udder health and subclinical mastitis | High SCC indicates poor udder health, affecting milk quality |
| TPC | Indicates bacterial contamination | High TPC correlates with lower milk quality and safety outcomes |
Routine monitoring of individual cow scc helps producers remove infected milk, protecting consumers and improving overall quality.
Animal Health
Somatic cell counts provide a direct link to mammary health in dairy cows. High counts often point to intra-mammary infection or lactational mastitis. When infection occurs, the mammary gland responds by sending more somatic cells to fight bacteria. The california mastitis test allows early detection of infection, reducing the risk of chronic mammary gland problems. Healthy mammary tissue produces milk with low somatic cell counts. Farmers track individual cow scc to monitor udder health and prevent the spread of infection. Early intervention lowers the chance of severe mammary gland damage and supports long-term animal health. Regular testing also helps identify cows with persistent infection, allowing targeted treatment and better herd management.
Industry Standards
Industry standards now require strict control of somatic cell count in milk. Regulatory agencies set limits to ensure udder health and reduce the risk of infected milk reaching consumers. The california mastitis test and automated systems help producers meet these standards. Economic data shows that poor management of somatic cell counts leads to revenue decline for dairy farms. The table below highlights the financial impact of high somatic cell counts:
| BTSCC Range (cells/mL) | Revenue Decline ($/cow/year) | GM Decline ($/cow/year) | Profit Decline ($/cow/year) |
|---|---|---|---|
| >200 to ≤400 | $228.5 | $155.6 | $138.6 |
| <14 kg/d production | $286.8 | N/A | N/A |
| ≥14 kg/d production | $446.5 (14-19 kg/d) | N/A | N/A |
| ≥19 kg/d production | $601.9 | N/A | N/A |
| Small-scale producers | $1,914.9 | $274.5 | -$224.1 |
| Profit range | $227.0 to -53.1 | N/A | N/A |
Maintaining low somatic cell counts protects both milk quality and farm profitability. By focusing on udder and mammary gland health, producers reduce infection rates and meet industry expectations for safe, high-quality milk.
