Under the new standards, raw milk must: Be cooled to 10ºC or below within four hours of the commencement of milking; and Be cooled to 6ºC or below within either:
Be held at or below 6ºC without freezing until collection or the next milking;and
Not exceed 10ºC during subsequent milkings.
We recommend you use a checklist to assess whether your farm cooling system is likely to meet the proposed new cooling regulations.
By completing this assessment you are taking a snapshot of your cooling performance, which only provides an indication of current temperature. It does not necessarily mean that you will meet the standards for 365 days of the year.
If you remove milk from the milking system to determine its temperature, do not return it to the vat.
Use an accurate temperature gauge suitable for use in the farm dairy (i.e. no glass thermometers).
If you answer No to any of the questions that apply to your situation, contact your refrigeration specialist to review your vat refrigeration and discuss changes needed to meet the new standards.
