While the legal limit for total bacteria in farm raw milk is 100,000/ml, milk with counts of 10,000 or less is considered desirable and achievable by most farms. Like somatic cells, bacteria produce enzymes that degrade proteins, fats, and other components, resulting in reduced product quality when counts are high.

Coliform detection in milk is usually an indication of poor plant hygiene. Coliform bacteria are usually killed by the hot water used to clean the plant, however, incorrect cleaning can lead to rapid growth of the bacteria. The test for coliforms involves aliquoting a sample of milk onto an agar plate. The plate is incubated for 24 hours and ...

When identifying milk quality issues, a standard plate count (SPC) test isn't enough. Elevated SPC could indicate dirty equipment, poor cooling, contaminants from the environment or a variety of other issues. While an SPC test can tell you when bacteria levels are high in raw milk, it can be difficult to identify where the problem is coming from.

This is an overall count of bacteria that can grow in the presence of oxygen in order to assess the overall bacterial load in the milk. Higher counts generally indicate improper sanitization, improper cooling or handling of the milk, older milk or diseased animals. The lower limit of detection for this test is 20 colony forming units (cfu)/mL.
