Exposure to Glyphosate-Based Herbicides and Risk for Non-Hodgkin Lymphoma: A Meta-Analysis and Supporting Evidence

Abstract
Glyphosate is the most widely used broad-spectrum systemic herbicide in the world. Recent evaluations of the carcinogenic potential of glyphosate-based herbicides (GBHs) by various regional, national, and international agencies have engendered controversy. We investigated whether there was an association between high cumulative exposures to GBHs and increased risk of non-Hodgkin lymphoma (NHL) in humans. We conducted a new meta-analysis that included the most recent update of the Agricultural Health Study (AHS) cohort published in 2018 along with five case-control studies. Using the highest exposure groups when available in each study, we report the overall meta-relative risk (meta-RR) of NHL in GBH-exposed individuals was increased by 41% (meta-RR = 1.41, 95% CI, confidence interval: 1.13–1.75). For comparison, we also performed a secondary meta-analysis using high-exposure groups with the earlier AHS (2005), and we determined a meta-RR for NHL of 1.45 (95% CI: 1.11–1.91), which was higher than the meta-RRs reported previously. Multiple sensitivity tests conducted to assess the validity of our findings did not reveal meaningful differences from our primary estimated meta-RR. To contextualize our findings of an increased NHL risk in individuals with high GBH exposure, we reviewed available animal and mechanistic studies, which provided supporting evidence for the carcinogenic potential of GBH. We documented further support from studies of malignant lymphoma incidence in mice treated with pure glyphosate, as well as potential links between GBH exposure and immunosuppression, endocrine disruption, and genetic alterations that are commonly associated with NHL. Overall, in accordance with evidence from experimental animal and mechanistic studies, our current meta-analysis of human epidemiological studies suggests a compelling link between exposures to GBHs and increased risk for NHL.

GMO Bt Crops May Not Be as Safe as Advertised

Cornucopia’s Take: Cry toxins are highly active protein toxins originally isolated from the bacterium Bacillus thuringiensis (Bt). They are genetically engineered into some GMO crops to perforate the gut membrane of insects that eat them. Poisoned pests stop eating and eventually die. Unfortunately, non-target animals, including monarch butterflies, swallowtail butterflies, lacewings, caddisflies, bees, water fleas, and mammals, are also susceptible to Cry toxins. Several influential studies used by the industry to show the safety of Cry toxins for non-target organisms are now in question. It appears the researched insects’ feed contained an inexplicably large dose of antibiotics, and antibiotics are known to inhibit the deadly action of Cry toxins.

Petition against Pioneer Hi-Bred’s application for open field trials of RNAi/gene silencing (DP-566113-9) GM maize

Say no to open field trials of new, untested gene silencing technology

Please support the African Centre of Biodiversity’s objection by signing and commenting on this petition against Pioneer Hi-Bred’s application for open field trials of RNAi /gene silencing (DP-566113-9) GM maize.

Once again, the GM industry aims to test a risky product on the SA environment and its citizens, who are being targeted as recipients of an unproven technology that promotes the private seed industry at the cost of our local, small-holder farmers and their seed and food systems.

Just as most people were going on holiday, on 21 December 2018, Pioneer Hi-Bred advertised in the Citizen newspaper its intention to make application to our GMO authorities for permission to conduct open field trials of a genetically modified (GM) maize variety, DP-056113-9, involving gene silencing techniques.

GMO: USDA Imposes the Worst Regulation Ever

In 2018, the overall cost for Americans to comply with regulations issued by U.S. government agencies decreased for the first time since that burden began to be measured in 2005. But that achievement wasn’t an across-the-board success story, because one federal government department bucked the trend by greatly increasing the regulatory burden on American food producers, where the cost of complying with new regulations issued by the U.S. Department of Agriculture (USDA) will ultimately be paid by all Americans whenever and wherever they might shop for food.
(.....)

The USDA’s regulators really believe its new bioengineered (BE) food labeling requirements will provide no measurable value to improving anybody’s health, or their pocketbook, or to the environment, where the only benefit they identify to justify the massive new regulatory burden lies in “eliminating costly inefficiencies of a state-level approach in BE disclosure”, where they single out the state of Vermont’s bioengineered food labeling regulations as even more costly.
