Milk Cooling Regulations

The Ministry for Primary Industries (MPI) New Zealand Code of Practice for the design and operation of Farm Dairies has new milk cooling standards.

In reference to http://www.foodsafety.govt.nz/elibrary/industry/dairy-nzcp1-design-code-of-practice/amdt-2.pdf, the following applies:

New Milk Cooling Standards

Raw milk must:
a) be cooled to 10ºC or below within four hours of the commencement of milking; and

b) be cooled to 6ºC or below within the sooner of:

i) six hours from the commencement of milking, or

ii) two hours from the completion of milking; and

c) be held at or below 6ºC without freezing until collection or the next milking; and

d) must not exceed 10ºC during subsequent milkings.

In situations 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 or extended milking” is defined as milking for six hours or longer from the time that milk first enters any bulk milk tank.

Implementation Date

From 1 August 2016 farm dairies that are:

a) new; or

b) undergoing any significant change to the secondary milk cooling system must meet the milk cooling requirements set out above

From 1 June 2018, all farm dairies must meet the milk cooling requirements set out above
