Replacing culture with molecular diagnostics

Mastitis causes an estimated loss of $40 billion in economic value annually.

The current diagnostic method, culture, is outdated and ripe for disruption

Valuable time is lost waiting for results

It currently takes 1-5 days for positive milk cultures and up to 7 days for negative calls



Culture can be inaccurate

40–50% of clinically abnormal milk samples tested with traditional culture will come back with a “no growth"

About Safeguard Biosystems - DairyGuard's Parents Company

Safeguard Biosystems is a molecular diagnostics platform  which has developed a product to identify an extensive menu of the most prevalent bacterial and fungal analytes. Our product identifies the organisms present directly from the sample, without the need for culture. Our product uses a proprietary multiplexed PCR and MicroArray that delivers reliable and accurate results within hours directly from the sample matrices

The DairyGuard assay offers a more comprehensive and accurate approach to milk quality assessment. By analyzing DNA from a single sample, DairyGuard can identify a wide range of bacteria, including mastitis pathogens, biofilm-forming bacteria, and spoilage organisms. This detailed analysis empowers dairy farmers to pinpoint the exact source of milk quality problems, whether it's related to herd health, milking equipment, or environmental factors.

The Benefits of DairyGuard include:

Safeguard’s technology has also been validated for human blood samples as a Laboratory Developed Test (LDT) by New York State's Department of Health, and is ISO 13485 certified. 


"I find very high correlation between the results obtained via DairyGuard and our more traditional culture methods…promising both for quality control, accuracy and surveillance of pooled samples such as pens and tanks…we will get quicker and more actionable results than sending samples to a referral laboratory." - DairyGuard Veterinary Customer
