Having given the green light to the National Foods bid for Dairy Farmers, the Australian Competition and Consumer Commission has now turned its attention to the rival takeover proposal from Parmalat SpA and the Murray Goulburn Cooperative.

The ACCC is calling for public comment on their bid.

The ACCC has identified a number of preliminary concerns about the proposed acquisition of DF by Parmalat and MG, and is seeking further information from the two companies.

The ACCC's decision to accept submissions from the market until August 7 has resulted in the body deferring its final decision on the bid until September 21.
