The new Ministry for Primary Industries milk cooling standards that came into effect on 1 June 2018 state that milk must:
Where there is continuous or extended milking, such as automated milking systems, the milk must enter the bulk milk tank at 6°C or below. (Continuous milking is defined as milking for six hours or longer from the time that milk first enters any bulk milk tanks).
|Milking time duration - hours||Milk Temperature at completion of milking||Time you have after the completion of milking to reach 6°C|
|Time - Hours||Temp - °C|
|1.0 to 4||N/A||2.0||6|
We recommend you use this 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 you will meet the standards for 365 days of the year.
|Y/N||Temperature at time of assessment|
|If you milk for less than 4 hours|
|Is the milk temperature two hours after milking less than 6°C?|
|Does the milk temperature stay below 10°C during the next milking? (Measure this by taking a temperature reading at the completion of the second milking into the vat)|
|If you milk for 4-6 hours|
|Is the milk temperature less than 10°C four hours into milking?|
|Is the milk temperature less than 6°C six hours from the beginning of milking?|
|Does the milk temperature stay below 10°C during the next milking?|
|If you milk for 6+ hours|
|Does the milk enter the vat at less than 6°C?|
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.
