Biotech giant Monsanto Philippines has asked government policy makers to look more closely at proposals for the mandatory labelling of products with genetically modified (GM) ingredients. The company's product development manager, Arnold Estrada, told BusinessWorld that while GM labelling is essential, policy makers have also got to consider the effects of such requirements on the food industry in the Philippines. Increased product analysis will inevitably prompt a rise in prices, "a substantial part of which would ultimately be shouldered by the consumers".
