Official documents obtained by Swiss NGO Public Eye show that 37 tonnes of profenofos were exported from Switzerland to Brazil in 2018. Profenofos is an insecticide which is banned in Switzerland due to its effects on health and the environment. According to Public Eye, Syngenta is the only company authorised to sell profenofos-based formulations in Brazil, where the NGO says profenofos residues were found in drinking water.

As criticised by Public Eye, the Swiss Federal Council at present refuses to prohibit the export of pesticides banned in Switzerland. 

Business & Human Rights Resource Centre invited Syngenta to comment on Public Eye's findings. Their response is available below.
