| Summary: | The production of farm bulk milk with low bacterial counts is a key quality index used by industry to help ensure the production of high-quality dairy products. The primary metrics used to determine the microbiological quality of bulk tank milk on a farm are the total bacteria count (TBC) and thermoduric bacteria count. To maintain TBCs and thermoduric counts at the lowest attainable levels, i.e., TBC ≤ 15,000 cfu/mL and thermoduric bacteria ≤ 200 cfu/mL, it is imperative that milk quality management is treated as a multi-faceted endeavor. Milking equipment cleaning, pre-milking teat preparation, milk filtration, cooling and storage, milking equipment maintenance and management of a cow’s environment and diet must each be managed with best practice in mind if farm bulk milk is to consistently attain low TBCs and thermoduric counts. This is especially important when using chlorine-free cleaning protocols, which are more complex than traditional chlorine-based cleaning methods and if not implemented correctly do not offer the confidence of achieving required hygiene standards. |
