Westland's acting chief executive, Hugh Little was "future-proofing" itself against any perception that A1 milk can damage the health of some people.

Lincoln University Professor, Keith Woodford, published the book, ‘Devil in the Milk’ last year. The book claims that the general milk supply in most western countries carries an A1 beta-casein, releasing a protein fragment which is a powerful opioid and should be avoided.

A2 milk does not have the protein fragment.

Westland Milk is New Zealand's second-biggest dairy cooperative after Fonterra.
