Contrary to widespread belief, the United States, which is the world’s largest producer of GM crops, does not require any safety testing for GM foods. The US Food and Drug Administration (FDA) merely encourages the developers of GM foods to undergo a voluntary consultation process and to submit a summary of its assessment of the GM food. The FDA does not conduct a comprehensive review of data generated by the developer, despite the fact that it is highly unlikely that a GM food developer is going to highlight any adverse effects of its product.
