What You Need To Know

When the change is taking effect

All farms must be compliant with new milk cooling regulations by 1 June 2018. New conversions must be compliant at installation.

What the new milk cooling regulations are

A Ministry of Primary Industries directive, the revised 1 June 2018 milk cooling regulations, can be downloaded here.


What's actually required to be compliant?

Compliance is determined by the vat milk temperature at the end of the stated timeframes. Not the temperature of milk going in. It's also meeting the stated temperatures at the end of your milking cycle whether that's single or blended.

Are you milking under or over 4 hours?

Under 4: Ensure your milk is down to 6°C within 2 hours of milking and that your blended temperature is no more than 10°C at the end of any additional milkings.

Over 4: You need to have your milk down to 10°C wihtin 4 hours of the commencement of milking. It must be then be down to 6°C wihtin 6 hours.

Snap chilling: This is only required if milking longer than 6 hours or using a robotic milker.

New cooling regulation confusion potentially costing farmers

Te Awamutu dairy farmer, Brian Chick, thought the new regulations were based on the milk temperature going into the vat, and so doubted his compliance.

He contacted his local supplier whose assessment indicated he needed to install one of 2 options, ranging in cost from $25k – $40k. Seeking another quote, Brian contacted Tru-Test whose assessment showed he was already compliant.
