This is because the production costs of GM foods will increase drastically in order to comply with the requirements of the mandatory labeling. According to the study done by Oregon State in 2002, the estimated annual costs of complying with the requirements of mandatory labeling GM foods in the US are in the range of $770 million to $2.8 billion (qtd. “Labeling of Genetically Modified (GM) Foods” 7).

However, the opponents’ arguments regarding the mandatory labeling of GM foods are incorrect. According to the article “Labeling of Genetically Modified (GM) Foods”, there was a study done by the European Commission-funded in 2006 and 2007 showing that 80% of consumers did not actively avoid buying the labelled GM food products while shopping at the supermarkets (qtd. in “Labeling of Genetically Modified (GM) Foods” 7). In fact, the second generation of GM foods may be positively accepted by consumers, although they are labelled. According to a survey conducted by the University of Otago Marketing Commerce in New Zealand in 2007, more than 50% of surveyed consumers rated GM foods positively regarding environmentally friendly and consumer benefits.
