AccuMast is an on-farm diagnostic kit developed by FERA Diagnostics & Biologicals that allows for the accurate differentiation of more than 11 different mastitis pathogens.

AccuMast can accurately detect the following bacteria:

• E. coli
• Klebsiella
• Enterobacter
• Pseudomonas
• Serratia
• S. uberis
• Streptococcus spp.
• Enterococcus
• Lactococcus
• Staphylococcus spp.
• Staphylococcus aureus

AccuMast Plus can distinguish Streptococcus agalactiae (S. agalactiae) from other Streptococcus species.

AccuMast delivers rapid results. Most bacterial organisms grow within 16 hours, and in many cases the causative organism can be identified in as little as 8–10 hours after incubation.

AccuMast has been scientifically proven to be highly accurate, with overall accuracy greater than 98%. In an independent University of Illinois evaluation (Ferreira et al., 2018) of four on‑farm culture systems, AccuMast was identified as the most accurate system for detecting mastitis‑associated pathogens.

AccuMast is the only on-farm diagnostic test that can detect S. aureus with an accuracy of nearly 100%.

AccuMast Plus can distinguish Streptococcus agalactiae (S. agalactiae) from other Streptococcus species.

AccuMast Plus provides the same precision and convenience as AccuMast, with an added advantage: it can distinguish Streptococcus agalactiae (S. agalactiae) from other Streptococcus.

Identifying the cause of mastitis is critical for effective treatment and prevention. Research shows that only 3–4 out of 10 mastitis cases benefit from antimicrobial therapy, meaning many mild E. coli or culture‑negative cases do not require antibiotics. By adopting pathogen‑based mastitis management, farmers can save significantly on labor, drug costs, and milk discard (ROI up to 10:1). Knowing the specific pathogen also guides prevention strategies—for example, if Staphylococcus aureus is the primary cause, culling infected animals and improving milking routines can reduce the spread of this contagious disease.

Accurate identification matters because treatment outcomes differ. Research shows intramammary antibiotic therapy does not improve cure rates for E. coli mastitis (97% vs. 98%). In contrast, cows with Klebsiella mastitis respond much better to antibiotics, with cure rates of 74% compared to only 18% in untreated animals (Fuenzalida & Ruegg, 2019). AccuMast is the only on‑farm culture system that can reliably distinguish E. coli from Klebsiella, helping farmers make informed treatment decisions.

AccuMast uses patented color‑coding technology to identify mastitis pathogens. Each culture medium contains chromogens bound to enzymatic substrates. When bacteria grow, their unique enzymes release the chromogens, which crystallize around the colony to create a distinct color pattern. This signature coloration makes it easy to distinguish different mastitis‑causing bacteria.

AccuMast and AccuMast Plus cost $7 per milk sample, providing accurate mastitis diagnostics at a cost‑effective rate for herd screening.

AccuMast and AccuMast Plus are manufactured in an ISO 5 environmentally controlled clean room and packaged using proprietary technology. This process ensures a 12‑month shelf life at room temperature. In contrast, other on‑farm culture systems typically last only 2–3 weeks and often spoil before they can be used.

AccuStaph is an on-farm diagnostic kit developed by FERA Diagnostics & Biologicals that detects Staphylococcus aureus mastitis infections in dairy cows. It is proven to be 100% accurate, cost‑effective, and allows testing of up to four milk samples per kit. AccuStaph helps farmers and veterinarians identify this contagious pathogen early, supporting better herd health and mastitis control.

AccuStaph has been scientifically proven to be 100% accurate in detecting Staphylococcus aureus infections in dairy cows.

Each AccuStaph kit can test up to four different milk samples.

Staphylococcus aureus is the most relevant contagious mastitis pathogen. Testing postpartum cows helps control its spread in dairy herds.

Yes. AccuStaph can differentiate fresh Staphylococcus aureus infections from chronic cows, helping farmers make better herd management decisions.

AccuStaph is highly affordable at $1.75 per milk sample, making herd screening cost‑effective.

AccuStaph's shelf life is 12-months from the date of manufacture.

AccuTreat is an on-farm diagnostic kit developed by FERA Diagnostics & Biologicals that detects and differentiates Gram‑positive pathogens causing clinical and sub‑clinical mastitis in dairy cows. It is accurate, practical, and affordable, and each package includes four quadplates, with each quadplate capable of testing up to four milk samples. AccuTreat helps farmers and veterinarians adopt pathogen‑based dry cow therapy, guiding antibiotic use only when necessary and supporting better herd health, mastitis control, and cost‑effective management.

AccuTreat is designed to detect Gram‑positive pathogens including Streptococcus, Lactococcus, and Enterococcus, as well as Staphylococcus aureus, Staphylococcus chromogenes, Staphylococcus haemolyticus, and other coagulase‑negative Staphylococci (CNS).

AccuTreat uses proprietary chromogenic media technology to differentiate Gram‑positive pathogens. Each quad‑plate contains selective media with chromogens linked to biochemical substrates and organism‑specific markers. When bacteria grow, their enzymes release the chromogens, producing distinct colony colors.

AccuTreat media uses a four‑section quad‑plate system that enables veterinarians and farmers to accurately diagnose the most important Gram‑positive mastitis pathogens that may require antibiotic therapy. Each quad‑plate can test up to four different milk samples, making it efficient and cost‑effective for herd management.

Dry cow therapy is a mastitis control strategy used during the dry period to protect udder health. In the United States, more than 90% of dairy operations practice blanket dry cow therapy, where all cows receive treatment at dry‑off to reduce new intra‑mammary infections. Farms with high milk quality and lower mastitis incidence may adopt selective dry cow therapy, treating only cows that show infection risk. With AccuTreat, farmers can accurately identify Gram‑positive pathogens and apply therapy only to cows or quarters that need it, supporting targeted treatment, reduced antibiotic use, and better herd health outcomes.

AccuTreat may be shipped and stored briefly at room temperature, but upon receipt it should be kept refrigerated at 2–8ºC and away from direct light. The media is light and temperature sensitive, so protect it from heat, moisture, freezing, and contamination. Once opened, refrigeration is recommended.

AccuTreat costs $3.50 per milk sample, offering accurate mastitis treatment guidance at an affordable price for herd management.

AccuTreat's shelf life is 12-months from the date of manufacture.
