Milk Lab

Discover the Full Range of Customized tests, including Milk Culture and PCR Services Offered by The Dairy Authority.

In the quest for optimal dairy health management, understanding the microbial profile of your milk is key. At The Dairy Authority, we help you determine the types of mastitis-causing bacteria infecting your herd, the source, and how the infection contaminates your animals. You can also learn how to control the spread of bacteria. These results can help you and your veterinarian work together to improve herd health and mastitis-control measures on your farm.

We offer diverse milk culture services tailored to your unique needs. From bacteria and mycoplasma to contagious pathogens, our comprehensive testing services provide the insights you need to ensure the health of your herd and the quality of your milk.


PCR testing for mastitis-causing pathogens

Mastitis results generated using PCR are completed in three hours or less. The test offers unparalleled Accuracy, which ensures the correct treatment is administered, minimizing the risk of resistance development and improving overall herd health. To learn more about PCR, click here.


Culture-based detection

We offer many different cultures to detect all kinds of mastitis-causing pathogens, including environmental and contagious pathogens. You can choose to culture for search of pathogens such as mycoplasma, Staph Aureus, or any bacteria.


Tank or co-mingled milk

Our comprehensive testing service for tank or co-mingled milk samples is ideal for dairy operations that pool milk from multiple sources, including groups of cows, individual pens, or complete bulk tanks, helping to ensure the safety and quality of your combined milk supply. Here at the Dairy Authority, we can customize these tests by only focusing on contagious pathogens, mycoplasma, or bacterial causes of mastitis, providing valuable insights into the microbial profile of your combined milk supply.

The Power of Comprehensive Milk Quality Testing:

By utilizing a combination of SPC, CC, LPC, and Somatic Cell Counts, The Dairy Authority can provide you with a complete picture of your milk's hygiene, safety, and overall quality. Here's why these four testing methods are crucial for maintaining exceptional milk quality:

Standard Plate Counts (SPC)


SPC is a vital indicator of milk quality, providing a measure of the total bacterial load in your milk. High SPCs can lead to spoilage and decreased shelf-life. By regularly monitoring your SPCs, you can identify and address any potential issues in your milking and storage practices, resulting in fresher, higher-quality milk.

Coliform Counts (CC)


CC measures the presence of coliform bacteria in your milk, which indicates contamination from pathogens that can reduce the quality of your milk. Our CC testing allows you to pinpoint areas of concern and take corrective action to ensure the safety and quality of your milk.

Lab Pasteurized Counts (LPC)


LPC testing determines the number of bacteria in your milk that can survive pasteurization. These bacteria have developed mechanisms to resist heat and other agents, such as sanitizers. They can also create a biofilm making it very tough to kill. LPC can help assess the cleanliness of your milking equipment and the efficiency of your wash cycles. By monitoring LPCs, you can identify and eliminate potential sources of contamination in your parlor, wash system and cooling system which could be preventing your operation from reaching the next level.

Somatic Cell Counts (SCC)


SCC provides a fast and efficient method for assessing milk quality. It is often used monthly on all cows in a herd to detect early mastitis or used in conjunction with culture during mastitis events to assess cure and determine success of treatment. High SCCs indicate mastitis which is a health issue in the udder of the cow. Mastitis can compromise milk quality and lead to animal welfare issues. By regularly conducting SCC testing you can detect and address mastitis earlier ensuring the well being of your herd and milk quality.

Preliminary Incubation Counts (PI)


PI counts can identify bacteria that grow in cold. This specific type of bacteria can damage the milk protein and fat during chilled storage, decreasing the milk’s shelf life. The PI counts can also be utilized to assess the cleanliness of the milking equipment and the cows.

Antimicrobial residue detection

An increase in public concern about antimicrobial residues in the food chain has led to increased pressure from regulatory entities for quality products free from residues. Any residue in the product leaving your farm may result in fines and significant losses from discarded milk. At the Dairy Authority, we utilize an array of tests with unmatched antibiotic residue detection to protect your operation from accidental product contamination leaving your farm. Reduce the risk of antimicrobial residue from improper treatment regimens due to mistakes with record keeping, failure to follow withdrawal times, multiple dosing, contaminated equipment, or short dry periods.

We offer tests that detect flunixins, beta-lactams, tetracyclines, and sulfa in urine and milk samples from animals treated with those medications.
