Standard Plate Count & Coliform Count (Calf Milk Panel)
Minimum of 6 ml milk each sample in a tube 1/4 to 3/4 full. Freeze samples immediately after collection. Samples must remain cold, preferably frozen. Refer to Best Practice: Milk Samples (link) for detailed instructions on how to collect a bulk milk sample.
This combination of tests is most often used to monitor the adequacy of pasteurization or heat treatment, storage conditions, and feeding equipment hygiene of waste milk or colostrum fed to calves. For more information, see the two Factsheets on Calf Feeding Systems. Results reported: cfu/ml SPC and Coliforms.
