After a month of headlines surrounding Fonterra's botulism recall it emerged today (28 August) that the company's whey protein concentrate was not, in fact, contaminated with a bacteria that can cause botulism. Facing stringent criticism at home, including an inquiry by the New Zealand government, this might seem like "good news" for the dairy giant. However, this fresh revelation is likely to lead to further questions over whether Fonterra's management overreacted to events - and why it took so long to get the all-clear. Katy Askew reports.
