A social media backlash is underway in the United Kingdom with well-known milk brands being poured down drains and people vowing never to buy them again.
What they're up in arms about is a feed additive that is designed to lower the climate impact of cows.
In December, Arla Foods, a Danish-Swedish company which owns the UK's biggest dairy co-operative, announced thirty of its farms would test the additive, named Bovaer (BOW VE AIR).
At the same time Fonterra posted on social media reassuring customers it is not using a feed additive designed to lower the climate impact of cows.
This is despite the product not being used in New Zealand, because it hasn't shown to be very effective in animals who spend their time mainly grazing on pasture.
Studies have shown the additive is safe for humans.
Independent agricultural advisor Julia Jones joins Emile Donovan to explain how New Zealand got caught up in the issue.
