The herd share is committed to regular testing to ensure the safety of us all.   The Oregon State University Veterinary Laboratory is close enough that the testing can be done without mailing the samples.  Herd shares in Oregon are not required to test.  The testing is a significant cost built into the herd share fee.  Inexpensive milk is likely not tested.  Since there are no specifications in Oregon for raw milk the standard adopted for the herd share comes from the Raw Milk Institute (http://www.rawmilkinstitute.org/).  

Our repeated tests in April 2016 were for the purpose of establishing a base line before we took our first customer.  

The Raw Milk Institute Specification includes:

  1. Total Standard Plate Count of 15,000 colony forming Units per milliliter (CFU/ml).
  2. Coloforms of a rolling three‐ month average of less than 25 CFU/ml. of raw milk

All data reported below is in the units of CFU/ml

Date                               Standard Plate Count    Coloforms

May 30, 2017                         990                          None detected

February 25, 2017               500                            none detected

The test results on January 27 triggered the two samples below.  The coloforms indicate bacteria from a non milk source which increase the probability of a pathogen being consumed by the herd share members.

In May of 2016 the herd was tested for Tuberculosis (TB), Caprine Arthritis and Encephalitis (CAE), Johne’s, Brucellosis and Caseous Lymphoma (CL).  All tests were clean Some of these can pass through milk to humans and others are important to ensuring clean kids to sell every year. 

In May of 2015 the herd was tested for Caprine Arthritis and Encephalitis (CAE), Johne’s, Brucellosis and Caseous Lymphoma (CL).  All tests were clean.
