Mexico has revoked US-based multinational agrichemical company Monsanto’s permit to commercialise its genetically modified soyabeans in seven Mexican states after allegations that the beans were found in unsanctioned areas.

According to Mexican news reports, the country’s agricultural sanitation authority SENASICA blocked sales of transgenic Monsanto soya in the states of Tamaulipas, San Luis Potosi, Veracruz, Chiapas, Campeche, Yucatan and Quintana Roo, Reuters wrote on 24 November.

The revocation, brought on by detection of modified soya in areas where it was not authorised, followed a 2016 suspension of the same license.

Monsanto rejected SENASICA’s claim, saying that the authority had not carried out an analysis of how the soya on which the decision was based was sown.

The company said its permit had been withdrawn on unwarranted legal and technical grounds and it would take the “necessary steps to safeguard its rights and those of farmers using its technology”.
