There’s been a lot of concern about the amount of Glyphosate (Roundup) we are exposed to in foods. There have been many questions raised in recent years about the health consequences of exposure: it is a suspected carcinogen, endocrine disruptor and implicated in infections caused by its antimicrobial action on gut bacteria.
Much more study is needed, as we simply don’t know what the consequences – to human, animal, soil and planetary health – will be of all these years of breathing, eating and drinking this pesticide.
As many people know, Glyphosate is used in GMO “Roundup-Ready” crops. It is also used pre-harvest on conventionally grown grain and cereal crops (allowed in Canada since 1992).
Monsanto’s selling point originally was that it was a ‘safe’ pesticide and claimed that it biodegraded harmlessly after killing weeds, and didn’t remain in the soil. Monsanto was successfully sued by French environmental groups ten years ago for these false claims, and the suit upheld on appeal.
Glyphosate has never simply disappeared after application. It has been found in breast milk, women’s blood, urine, animals’ organs, air, rain, and streams, and has crossed the placental barrier in animals. The Detox Project is doing valuable work in trying to establish how widespread the contamination is in humans by inviting people to participate in its study.
The Canadian Food Inspection Agency has found glyphosate residue in just about one-third of 3,188 food samples tested (fresh produce, processed fruits and vegetables, grain products, juice and other beverages, bean-pea-lentil products, soy products and baby food). Nearly half of the pea/bean/lentil samples contained glyphosate residue; grain products and soy were also high; safety levels were exceeded in 4% of grain and 1.3% of all foods tested. One-third of the baby foods tested contained glyphosate, although none scored above the levels considered safe.
This of course doesn’t address the toxic load we all carry in this contaminated world. A safe level of one toxin may accumulate over time and possibly interact with other toxins we ingest. And we don’t know what else is in Roundup as the adjuvants (other ingredients) in patented formulae don’t have to be disclosed in the interests of protecting the profit margins of the manufacturer. And the CFIA has decided not to disclose the details of the foods they tested – brands, varieties, anything we might want to use to make better food choices – “for confidentiality reasons”.
So for me, certified organic food continues to be the best choice, wherever I can afford it.
