Lyall Thurston, long-time folate campaigner and parent of son with spina bifida; and Katherine Rich, CEO of the NZ Food and amp; Grocery Council and former National MP - says if any government decides to mass-medicate every bread-buying New Zealander with a certain additive, it has to be very sure that the costs to the community don't outweigh any health benefits, and that there are no long-term ill-effects on the population.
