The health ministry is set to amend the Prevention of Food Adulteration Rules, 1955 to introduce the provision of mandatory labelling of genetically modified (GM) foods, likely to be imported or produced in the country. An expert committee set up by the ministry under the chairmanship of the additional director-general of the National Institute of Communicable Diseases, Shiv Lal has recommended mandatory labelling of GM food and food ingredients, without any threshold limit. The committee has defined GM food as those composed of or containing genetically organisms obtained through modern biotechnology. Even the GM processed food would be labelled. The expert panel included representatives from the industry, Indian Council for Medical Research and farmer leader Yudhvir Singh.
