A simple guide to milk cooling regulations

Effective from June 1, 2018, the Ministry of Primary Industries has made changes to the current milk cooling regulations to keep New Zealand in line with global market requirements.

The rules state that raw milk must:

  • Be cooled to 10°C or below within four hours of the commencement of milking; and
  • Be cooled to 6°C or below within the sooner of:
    • Six hours from the commencement of milking, or
    • Two hours from the completion of milking; and
  • Be held at or below 6°C without freezing until collection or the next milking; and
  • Must not exceed 10°C during subsequent milkings.

The best way to find out if you’re going to be compliant is to have your local DTS On-Farm Solutions specialist carry out a Milk Cooling Assessment. If you need to make changes they can work with you to determine the best solution for your business.
