The Soil Association warns that up to 30% of UK bread tested contained glyphosate, the main ingredient in most commercial weedkillers.  Only certified organic bread can guarantee it does not contain glyphosate.

Glyphosate is the most widely sold weedkiller in the world. You may recognise it as the active ingredient in Roundup. The big chemical companies advise farmers to spray their wheat crops with glyphosate a few weeks before harvest – to kill the crop and remove weeds to make it easier for them to harvest.

There are no safe levels of glyphosate in food.
