Fresh or Frozen Milk Samples for Cultures
USU Dairy Extension Newsletter
Collecting milk samples for culturing so that problem organisms can be identified is critical to proper treatment of cows with mastitis. It is common practice on many dairies to collect the sample, then store it in the refrigerator or freeze it until it can either be taken or shipped to the laboratory. Most laboratories have protocols for collection and handling of samples, but the question sometimes is what is appropriate handling for a sample if I am interested in bacteria X, Y or Z? A recent article attempted to address this question for Mycoplasma and its findings are relevant to other bacterial species.
