Glyphosate and Cancer: What does the data say?

Guest Author: Andrew Kniss
In March, 2015 the International Agency for Research on Cancer (IARC) announced that glyphosate would be added to their list of agents that are “probably carcinogenic to humans.” Glyphosate wasn’t the only pesticide added to the list, but as Nathanael Johnson noted at Grist, glyphosate tends to be something of a lightning rod due to its association with genetically engineered (Roundup Ready) crops. Let me start by pointing out I’m pretty late to the party writing about this.

17 of 17 – Can Glyphosate Research Be Trusted?

GUEST AUTHOR: Iida Ruishalme
In my series 17 Questions about Glyphosate, last but not least comes a post about the integrity of research, how funding may influence research results, and what corporate involvement with scientists may entail. And if scientists mostly are not influenced by industry, why are there so many conflicting study results?

14-16 of 17 – Glyphosate and Field Ecosystems

GUEST AUTHOR: Iida Ruishalme
In my series 17 Questions about Glyphosate, question 14. deals with glyphosate-resistant weeds: whether they pose a problem, and why campaigners against glyphosate should be the last ones to worry about this particular issue. Question 15. looks at the soil ecosystems: what do we know about the effects of glyphosate on soil micro-organisms? Does it affect nutrient balance and mineral uptake? Plus comments on what one troubled study found out about earthworms. Question 16. delves into whether there is a relationship between glyphosate and the situation of Monarch butterflies or bees.

In my series 17 Questions about Glyphosate, question 13. looks at glyphosate and its impacts on farming methods and the environment.

Even if glyphosate poses no risk for the consumers, perhaps its problems lie in the effects on the environment? Let’s look at some of the details.

7-12 of 17 – Glyphosate in Wind, Rain; Down the Drain?

Guest Author: Iida Ruishalme
Series 17 Questions about Glyphosate! In questions 7-11 I go through the evidence for whether glyphosate can be detected, and if so then in which quantities, in each of the following: air and rainwater, urine, breastmilk, wine, and wheat. I have also added extra sections on glyphosate in honey, vaccines, and tampons.

Question 12. delves into the common verbal images of farmers ‘drenching’ their fields in pesticides, and how much farmers actually use.

5 of 17 – Could Glyphosate be another case like DDT or Thalidomide?

Hearing science-speak conclusions like “failure to show adverse effects”, or “no correlation found”, or “not likely to pose risk” often leaves a layman out cold in the mists of the inherent scientific uncertainty. For our everyday logic, there is a threshold of such little perceived risk, where we simply declare something safe. But science holds fast to the humble intellectual honesty of saying “despite all our best efforts, there is still a very slim chance of an effect that could become evident in some unknown context in the future”. That may make our everyday brains feel uneasy.

GUEST AUTHOR: Iida Ruishalme
In my series 17 Questions about Glyphosate, question 4. looks at glyphosate and its potential to affect our gut bacteria. This is one of the favourite returning points for many who find the newness of the field of microbiome research a reason be extra cautious, and in the process, sometimes jump into some rather hasty conclusions.

GUEST AUTHOR: Iida Ruishalme
Much media and public attention on glyphosate followed after World Health Organisation subgroup, International Agency for Research on Cancer (IARC) declared that according to their classification, glyphosate falls under substances 2a – “probably carcinogenic”. What the media attention often failed to report is that IARC does not actually look at risk – how big is the risk for said carcinogenic effects? What levels are safe and what aren’t?

17 Questions About Glyphosate

Many worry about pesticides for health or environmental reasons and the most common target of general concern is undoubtedly glyphosate, the active ingredient in the famous weedkiller RoundUp. I find that the best thing to do when something worries me is to find out more about it.

“I don’t want to eat food that makes insects stomachs explode! / I don’t want to eat food that’s been bred to withstand being drenched in toxic herbicides”

How often have you heard some version of:

“I don’t want to eat food that makes insects stomachs explode! / I don’t want to eat food that’s been bred to withstand being drenched in toxic herbicides”

This may be the most common misconception out there. Let’s try to reconnect it with reality a little bit.
