Large U.S. farm study finds no cancer link to Monsanto weedkiller

LONDON (Reuters) - A large long-term study on the use of the big-selling weedkiller glyphosate by agricultural workers in the United States has found no firm link between exposure to the pesticide and cancer, scientists said on Thursday.

Published in the Journal of the National Cancer Institute (JNCI), the study found there was no association between glyphosate, the main ingredient in Monsanto’s popular herbicide RoundUp, “and any solid tumors or lymphoid malignancies overall, including non-Hogkin Lymphoma (NHL) and its subtypes”.

It said there was “some evidence of increased risk of acute myeloid leukemia (AML) among the highest exposed group”, but added this association was “not statistically significant”.

The findings are likely to impact legal proceedings in the United States against Monsanto, in which more than 180 plaintiffs are claiming exposure to RoundUp gave them cancer - allegations that Monsanto denies.

The findings may also influence a crucial decision due by the end of the year on whether glyphosate should be re-licensed for sale across the European Union.

EU countries had been due to vote on the issue on Thursday, but again failed to agree to a proposal for a five-year extension.

The EU decision has been delayed for more than a year after the World Health Organization’s International Agency for Research on Cancer (IARC) reviewed glyphosate in 2015 and concluded it was “probably carcinogenic” to humans. Other bodies, such as the European Food Safety Authority, have concluded glyphosate is safe to use.

The research is part of a large and important project known as the Agricultural Health Study (AHS), which has been tracking the health of tens of thousands of agricultural workers, farmers and their families in Iowa and North Carolina.

Since the early 1990s, it has gathered and analyzed detailed information on the health of participants and their families, and their use of pesticides, including glyphosate.

David Spiegelhalter, a professor of the Public Understanding of Risk at Britain’s Cambridge University who has no link to the research, said Thursday’s findings were from a “large and careful study” and showed “no significant relationship between glyphosate use and any cancer”.

He added that the possible association with AML “is no more than one would expect by chance”.

Reuters reported in June how an influential scientist was aware of new AHS data while he was chairing a panel of experts reviewing evidence on glyphosate for the International Agency for Research on Cancer (IARC) in early 2015.

But since it had not at that time been published, he did not tell the expert panel about it and IARC’s review did not take it into account.

The publication of the study on Thursday comes more than four years since drafts based on the AHS data on glyphosate and other pesticides were circulating in February and March 2013.

In a summary of the results, the researchers, led by Laura Beane Freeman, principal investigator of the AHS at the U.S. National Cancer Institute, said that among 54,251 (pesticide) applicators studied, 44,932, or 82.9 percent, used glyphosate.

“Glyphosate was not statistically significantly associated with cancer at any site,” the summary said.

Scott Partridge, Monsanto’s vice president of strategy, said the study results clearly showed the weedkiller was safe.

“This is the largest study of agricultural workers in history, over the longest period of time,” he told Reuters. “It is the gold standard,... and it definitively demonstrates in a real-world environment that glyphosate doesn’t cause cancer.”

And Roundup is still killing off bees. Ban the stuff and put people to work pulling weeds. That's what I do at my place !

"And Roundup is still killing off bees"... Right - I agree that Roundup is doing a lot of things and should be banned; the problem is that the chemical at issue is glyphosate, and as dsert says, Roundup is more than glyphosate.  

The problem is that everyone is focused on glyphosate, which Monsanto is arguing to be "safe" and no one really seems to be looking at the other chemicals.  Until they do, I think Roundup is here to stay, since it's Monsanto's number 1 money maker...

Pull weeds?? What's that??  LOL

Actually, if I have weeds that prove more to be more than I handle, I use a solution of vinegar and epsom salt.

How far do you have to go look and find that Monsanto contributed to this study "financially"?

It's been known for a couple years that glyphosate, by itself, is not immediately carcinogenic. But Round Up is more than just glyphosate, and, like fracking fluid, you've got other chemicals in there that are 'proprietary information' and may be carcinogenic on their own or in combination with glyphosate. Also, the mechanism by which glyphosate kills broadleaf plants also kills the good gut bacteria in your body. So go ahead and use it for salad dressing - you can always get a fecal implant. Personally, I worry more about what Neo-nic' pesticides are doing to our pollinators. There are plenty of other things more likely to lead to our extinction than Round Up.

We all know that money talks and if there's enough of it, it can, literally, scream.  We, also, know that study results can be skewed to say whatever the money wants them to say...
