In February 2010, the Indian government placed an indefinite moratorium on the commercial release of Bt brinjal. Prior to this decision, numerous independent scientific experts from India and abroad had pointed out safety concerns regarding Bt (insecticidal) brinjal based on data and reports in the biosafety dossier that Mahyco, the crop developer, had submitted to the regulators.
The then Minister of the Ministry of Environment and Forests Jairam Ramesh had instituted a unique four-month scientific enquiry and public hearings. His decision to reject the commercialisation of Bt brinjal was supported by advice from renowned international scientists. Their collective appraisals demonstrated serious environmental and biosafety concerns, which included issues regarding the toxicity of Bt proteins resulting from their mode of action on the human gut system.
