A campaign by UK charity the Soil Association is calling on bread manufacturers and retailers to stop using wheat that has been sprayed with glyphosate.
Glyphosate, the world’s most used herbicide, is commonly sprayed on wheat crops just before harvest to kill weeds and make harvesting easier, and government testing has shown the chemical to be present in up to 30 per cent of UK bread, the Soil Association says.
The bread industry says the levels are very low and the association is unfairly targeting bread. However, the Soil Association points out that the European Union’s maximum residue limits were set before April this year, when the United Nations International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans”.

Recently, Australian Herbicide Resistance Initiative (AHRI) researchers in Western Australia detected the nation’s first glyphosate resistant wild radish (Raphanus Raphanistrum L.) population.
This discovery is big news in Australia and should serve as another warning – if we rely exclusively on herbicides they will eventually fail.
Glyphosate resistance is a global issue
This issue is not limited to Australia. The USA is now the world leader in glyphosate resistant weeds and Australia may soon follow suit, unless we incorporate more diversity into our weed control programs.
Professor Stephen Powles, AHRI Director, says that the introduction of glyphosate resistant crops in the US was so effective that there was almost universal adoption and then exclusive use of glyphosate for weed control.
“Initially the weed control was outstanding, encouraging even more overreliance on glyphosate. However, the economic savings experienced are now being eroded by the evolution of glyphosate resistant weeds.
“Nearly all the US corn, soybean and cotton crops are glyphosate resistant and many of these fields are starting to show glyphosate resistant weeds. This problem will only double, triple and quadruple in the coming years due to over-reliance on glyphosate,” Professor Powles
