Fonterra chief executive Andrew Ferrier has taken a step back in the confusing picture of the trial of former head of the Sanlu dairy company over the contaminated milk scandal in China.
State-run Xinhua news agency said yesterday that Tian Wenhua, 66-year-old former general manager of the now bankrupt Sanlu Group, pleaded guilty to charges of "producing and selling fake or substandard products".
Fonterra had a 43 percent share in Sanlu.
Mr Ferrier said last night he had heard conflicting reports from the trial of Tian's trial, The New Zealand Herald reported.
But another company spokesman later contacted the Herald to say Tian had "absolutely and unequivocally" pleaded not guilty to the charges she faced.
The tainted product resulted in the deaths of six babies and illness of nearly 300,000 others earlier this year.
Tian appeared with three other company executives at a court in Shijiazhuang, capital of northern Hebei province. No verdict was announced, and it was unclear whether they could face the death penalty, or life imprisonment.
Fonterra had been under the impression yesterday that Tian had pleaded not guilty, Mr Ferrier said today.
"However there were other reports that she had pleaded guilty.
"Fonterra was not present at the trial. It is not appropriate for Fonterra to make any further comment while the Chinese court is deliberating its verdict," he said.
Media reported that Tian admitted in court testimony that she had known of problems with the company's products for two months before she told authorities.
She had submitted a written report on the melamine situation on August 2 -- the same date Fonterra was told of the issue.
Mr Ferrier told the Herald any suggestion that Tian knew about it earlier was "absolute news" to his company.
Fonterra was also surprised by charges that Sanlu sold products after it knew they were contaminated.
Mr Ferrier said August 2 was "the absolute first that anybody in Fonterra had ever heard of this and from that moment on we pushed to recall the product".
Chinese authorities had made no attempt to press charges against Fonterra, which has written off its 43 percent shareholding in Sanlu for a loss of $210 million.
