NEW YORK - Swiss food group Nestle SA may sell about 10 to 15 per cent of the $11.9 billion baby food business it is buying from Pfizer Inc to address antitrust concerns, Bloomberg News reported on Monday.

Nestle may have to offload divisions in countries including Australia, Thailand and Venezuela, Bloomberg said, citing people with knowledge of the matter.

Bloomberg reported that Nestle spokesman Robin Tickle said it was "premature to comment on and prejudge the decisions of the regulatory authorities".

A spokesman for Nestle could not immediately be reached for comment by Reuters.

Nestle, the world's biggest food company, won a high-stakes fight for Pfizer Nutrition, which makes 85 per cent of its sales in emerging markets.

The acquisition is Nestle's biggest deal to date.

Consumer product companies and private equity funds may be interested in the assets, the report said.
