Glyphosate, an herbicide used in Roundup, was up for renewal of its EU approval. While the EU food safety authority found glyphosate was not carcinogenic, other groups disagreed. This caused political issues for EU member states trying to decide whether to support or oppose glyphosate's approval. The EU granted a temporary extension of approval until 2017. After Brexit, the UK may not have a vote in further discussions and glyphosate's future approval is uncertain, as the EU could restrict UK agricultural imports if it disapproved of glyphosate use.
