A new scientific analysis concludes that the European Food Safety Authority's (EFSA) claim that glyphosate is not genotoxic cannot be justified on the basis of manufacturers’ studies. Of the 53 industry-funded studies used for the EU’s current authorization of glyphosate, 34 were identified as "not reliable", 17 as "partly reliable" and only 2 studies as "reliable" from a methodological point of view.
The results of the first ever long-term organic diet intervention study among pregnant women were published today in Environment International . Researchers found that pregnant women’s exposure to pyrethroid insecticides was significantly reduced by adding organic fruit and vegetables to their conventional diets during the second and third trimesters of pregnancy.
Prenatal exposure to pyrethroid insecticides has been associated with poorer neurological and cognitive development in children. Diet – and in particular, fruits and vegetables – is among the primary sources of exposure to pyrethroid pesticides . Consequently, reducing exposure among pregnant women presents an important prevention opportunity for the healthy development of children, starting in utero.
Genon Jensen, Executive Director at the Health and Environment Alliance (HEAL), said: “This study shows that consuming organic fruits and vegetables during pregnancy can make a big difference in lowering your pesticide exposure. Health professionals like obstetricians, midwives and paediatricians can play a crucial prevention role by advising future mothers during their pregnancy to reduce pesticides exposure by choosing organic fruit and vegetables.”
“Equally important, EU policy makers should address the hidden health costs of the current Common Agriculture Policy and choose to transition to food and agriculture systems that protect public health, future generations and the environment instead, and are accessible and affordable to all.”
The study was conducted with 20 women who previously reported eating exclusively conventionally grown food for a period of 24 weeks. Participants received deliveries of either conventional or organic fruits and vegetables during the study period and collected spot urine samples every week. Samples were analysed for biomarkers of organophosphate (OP) and pyrethroid insecticides.
The difference in biomarkers of pyrethroid insecticides between women consuming conventional or organic food was the most significant:
- Concentrations of biomarker 3-PBA (a nonspeciﬁc metabolite of several pyrethroids) , were 3,5 times higher in samples collected from women receiving conventional food compared to those receiving organic food.
- Biomarker trans-DCCA (a metabolite of permethrin, cypermethrin, and cyﬂuthrin) was detected four times more frequently in women in the conventional compared to the organic produce.
The study results were not statistically significant for biomarkers of organophosphate insecticides.
