Dr Pat Tuohy, chief adviser of health from the Ministry of Health, said parents could reassure themselves of the safety of formula. Ms Hart said despite this, and supermarkets tightening security, any risk was not worth it. "They are innocent kids. It's a child, it's a life, it's not worth it," she said.
Ms Hart said because of Zoey's age she would be switching her to alternative milk such as rice or cow's milk. However she said some parents weren't able to do the same. "I work at a daycare and we've got it [information] at the front so parents can see, and quite a lot of them are like well 'what are we going to do?' I feel sorry for people who can't switch their kids because of their age and some parents aren't able to breastfeed."
Ms Hart said she was frustrated the public was not informed earlier. " ... it would have been better if they let people know earlier even if there's only a slight risk."
Mr Tuohy encouraged parents with concerns to check products for tampering. Security has also been stepped up at Fonterra's milk powder plants at Kauri and Maungaturoto. Parents with any concerns can call Plunketline on 0800 933 922 or Healthline on 0800 611 116 for advice.
