A customer shops in an aisle stocked with Nutricia milk powder products in a supermarket in Auckland August 6, 2013. Nutricia, a Danone subsidiary which manufactures the Karicare brand, announced a blanket ban on two of its infant products in New Zealand late on Monday. Nutricia is supplied by dairy giant Fonterra, which is at the centre of a widening contamination scare involving whey protein products containing a bacteria which can potentially cause botulism.
