Our Milk Testing Protocols

First thing’s first: I need to apologize for the delay in making this post. Earlier this year I wrote about the importance of sanitation and testing when it comes to raw milk, and then I never got around to writing about what we do on our farm.

Let’s talk about sanitation!

  • We use a closed milking system to prevent dirt, hair, feces, and insects from contaminating our milk. 
  • During milking, we wear gloves, use teat dip, and use a clean towel to wipe each goat’s teats.
  • After milking, we bottle and chill milk immediately. Milk is poured into glass bottles that have been sanitized with diluted bleach.
  • We wash all of our milking equipment with soap and hot water, followed by an acid rinse, after every use.
  • We soak all of the critical components of our milking system in a chlorine sanitizer solution before every use.
  • We regularly clean our goat’s pens so that they’re always laying on clean bedding. This helps to prevent mastitis as well as fecal contamination from dirty animals.

I’ve spent the past few months brainstorming the best ways to aggregate and present all of our milk test data. We run standard plate counts and Coliform/E. coli tests on a bi-weekly basis. I decided that, for simplicity’s sake, I am going to make available the averages for each test that we run. The numbers for the current year are a rolling average, updated in real time: Milk Test Averages

So what do these numbers mean?

The standard plate count (or aerobic plate count) is a quantifies the amount of bacteria in our milk. This test counts both beneficial and potentially harmful bacteria. Although the state limit is 30,000/mL, we aim to keep the overall bacteria level of our milk under 1,000 cfu/mL to reduce the likelihood that harmful bacteria may be present.

A Coliform count lower than 10 cfu/mL is indicative of excellent sanitation. While we always strive for excellence, our average may not fall below 10 this year, as we had a few slightly elevated Coliform counts at the beginning of the milking season. We’ve since made adjustments to our sanitation procedures to meet our goal. 2020 is our first year testing and selling milk, so we are still learning!

We also use a weekly CMT (California Mastitis Test) to monitor the SCC (somatic cell count) of each of our does throughout her lactation. An elevated SCC indicates the presence of mastitis (an infection of the mammary glands). If one of our goats tests positive, we can immediately begin milking her separately and discarding her milk until we are certain that the infection has cleared.

It is possible to test for specific pathogens, such as Salmonella, Campylobacter, and Listeria. However, doing so is usually unnecessary so long as the APC and Coliform counts are consistently low.

Baby Goat Care

It’s the most wonderful time of the year: kidding season! While our does aren’t due until mid-April, we’ve noticed a lot of babies being posted for sale by farms throughout NY, VT, and PA. As breeders, we believe that we have a duty to educate future goat owners about the best practices for raising happy, healthy kids. For this reason, I spent the winter creating a comprehensive kid care guide (PDF download) that I’d like to share with you, covering the following topics:

  • Housing (Fencing, Shelter, Toys)
  • Feeding (Bottle-Feeding, Grain, Forages, Minerals)
  • Health (Vaccination, Hoof Trimming, Disbudding, Castration, Detecting Illness)
  • Socialization & Companionship

I referenced a few helpful resources at the end of the guide, but I’d like to take this opportunity to list several more that I consult regularly.

I wanted to keep this guide short and simple, while still touching on all of the critical aspects of kid care. I am by no means a goat expert; our family began raising goats in 2018, prior to then I worked with dairy cattle, and I studied animal health while completing my Agribusiness degree. If any more seasoned herdsmen have any changes to suggest, I would welcome them to share their insight and I will certainly take it into consideration as I revise the guide in the future.
