Rounding Up the facts on Glyphosate with the EPA's Dr Shaun Presow

Glyphosate, or 'Round Up' as it commonly known, is one of the world's most widely used herbicides. It’s been approved for use in New Zealand since the 1970's, but in recent years its safety has been called into question here and abroad. Six months ago, the New Zealand’s Environmental Protection Authority (EPA), the authority charged with looking into the safety and efficacy of our agrichemicals, declined to review the approval of Glyphosate saying there are no grounds ornew evidence for a review. Joining the conversation to discuss this decision and the safety of Glyphosate is the EPA's manager for Hazardous Substances Reassessments, Dr Shaun Presow.
