Poison Fruit    Dow Chemical Wants Farmers to Keep Using a Pesticide Linked to Autism and ADHD (The Intercept, 14 January 2017) A fascinating article reviewing the history of the organophosphate chlorpyrifos regulation in the United States. Reviews the research directly linking it to autism and several other disorders, the need for suing the US EPA to get action and Dow's constant efforts to keep chlorpyrifos on the market including bad studies, threats to sue the EPA, and success in changing the law. Long and lots of links." While the US nationwide autism rate is now one in 68, for women who lived near fields where chlorpyrifos was sprayed during their second trimester, the chance of having a child with autism was closer to one in 21." Effects on children's brains occur at levels 20 times below the EPA’s safety level. In spite of the evidence linking autism to environmental causes, the National Institute of Health (NIH) is only funding studies on environmental causes at 1/20th of the genetic ones. Dow's latest efforts: "Instead, the chemical industry has renewed its efforts to derail the proposed regulation. On November 29, (2016)  CropLife America launched a Hail Mary effort to stop the ban. The business group petitioned the head of the office of pesticide programs to “cease regulatory decision making” on chlorpyrifos until it has developed standards “for acceptance of epidemiologic studies in human health risk assessment,”" a process that could easily take several years.". However, there are still several potential ways it (Dow) could circumvent the regulation without technically defying the law.

SNAP comment: Here we have it from the mouth of industry: there is currently no process “for acceptance of epidemiologic studies in human health risk assessment.That is why it is so easy for regulatory agencies to ignore or set aside epidemiological studies in their pesticide re-evaluations, especially when the committees consist of several 'regulatory' scientists or others deriving their income from the pesticide industry. I don' t believe there is much of a mechanism or standard for regulatory agencies to evaluate anything but the studies mandated for registration. As of 16 January 2017, there are still 29 chlorpyrifos products registered for use in Canada.

Glyphosate testing

Press Release: New Study: Glyphosate persists! And European top soils are contaminated with it. (PAN Europe, October 13, 2017)  "45% of Europe’s top soil contains glyphosate residues, demonstrating the over-reliance of the EU agricultural model on this harmful herbicide chemical. In contrast to what its manufactures2 purport, glyphosate persists in soils affecting not only soil fertility and crop quality, but also human and environmental health."   "The concentrations of glyphosate and AMPA found in the study have been shown to be toxic to soil organisms such as earthworms3, beneficial bacteria4 and fungi5 , as glyphosate weakens down plants’ natural defences making them susceptible to pathogens6." 

Glyphosate on feed affects livestock: vet (Western Producer, 19 October 2017)  A veterinarian in Shaunavon, Sask., believes feed with glyphosate residue adversely affects cattle health. Dr. Ted Dupmeier, who operates his own practice at Shaunavon, told about 50 people at a recent event he called an awareness seminar that he began investigating after being unable to diagnose problems in a dairy herd in which cows were inexplicably dying. He said after removing feed that had been sprayed with glyphosate the problems were resolved. SNAP Comment: Positive that this story was actually worth an article in the Western Producer. This "anecdote" supports the facts presented in the video Poisoned Fields - Glyphosate, the underrated risk? (HD 1080p)  (Jan 25, 2016)

Poisoned Fields - Glyphosate, the underrated risk? (HD 1080p)  (Jan 25, 2016)  Glyphosate is the world’s most widely used weed killer. Some claim it is completely harmless, others say it is a serious health hazard for man and animals. A topical investigation into a controversial substance.

Sustained Glyphosate Use Reveals Risks to Soil and Environmental Health  (Beyond Pesticides, July 21, 2017)   Researchers have found that, after years of consistent application to agricultural crops, the chemical accumulates and persists in area soil, particularly at the root zone and in the top few millimeters. In part, the accumulation is due to the fact that only 5% of any applied dose tends to reach the weed it is intended to kill, while the rest lands on the soil. In addition, the chemical is likely released in soil from the roots of plants that have absorbed the compound, as well as from decomposing plants that have been exposed to it. This finding of persistence belies the common assumption that the chemical rapidly degrades in soil.

Agricultural Uses of Antibiotics Escalate Bacterial Resistance. Organic Leads in Prohibiting Antibiotic Use. (Pesticides and You, winter 2016-17)    Presents information on antibiotic use in animal and fish production as well as in agriculture for the control of bligh and other bacterial crop diseases. Discusses residued in food and water. The use of glyphosate, a registered antibiotic, in crop production dwarfs knows uses of all other antibiotics by at least 3 times. Gives some of the organic alternatives. Unfortunately only US data with few international for contaminated fish. 

Continued Use of Glyphosate Herbicide in EU Called into Question by Renowned Toxicologist  (Beyond Pesticides, June 5, 2017)  Dr. Portier asks that the evaluations by EFSA and EChA be “repeated for all toxicological endpoints and the data underlying these evaluations be publicly released.” Based on these failures in data analysis, the final assessments conducted by the EU agencies are insufficient to allow for glyphosate’s license extension, he said...In 2015, Dr. Portier presented at a scientific briefing in London and stated, “Glyphosate is definitely genotoxic. There is no doubt in my mind.” Genotoxicity is the ability of a chemical agent to damage the genetic information within a cell, causing mutations that may lead to cancer. According to Dr. Portier’s presentation, there is strong evidence that glyphosate and its formulated products are genotoxic and an oxidative stressor. Several links.

Monsanto Sued for Misleading Labeling of Popular Herbicide Roundup  (Beyond Pesticides, April 10, 2017) Two nonprofit organizations on Friday filed a lawsuit against Monsanto for misleading the public by labeling its popular weedkiller Roundup as “targeting an enzyme found in plants but not in people or pets.” This lawsuit charges that this statement is false, deceptive, and misleading, because the enzyme targeted by glyphosate, the active ingredient in Roundup, is, in fact, found in people and pets.

Nearly a third of food samples in CFIA testing contain glyphosate residues (CBC News. Apr 13, 2017) The Canadian Food Inspection Agency's report on testing of glyphosate is titled "Safeguarding with Science: Glyphosate Testing in 2015-2016, and was published on its website this week. more under food 

Why Is Glyphosate Sprayed on Crops Right Before Harvest? (EcoWatch, 5 March 2016) ...The pre-harvest use of glyphosate allows farmers to harvest crops as much as two weeks earlier than they normally would, an advantage in northern, colder regions...The practice spread to wheat-growing areas of North America such as the upper Midwestern U.S. and Canadian provinces such as Saskatchewan and Manitoba...“It does help hasten dry down and controls grain weeds and other material that slows down the threshing practice," Ransom said. “It has an important role in areas where it's wet." SNAP Comment: This article calls the use of glyphosate prior to harvest dessicationIn Canada, glyphosate is not registered for dessication (or as a dessicant), but for "pre-harvest spraying", which amounts to the same thing without saying the word...For instance the Vantage label indicates to apply at "30% or less grain moisture content. This stage typically occurs 7 to 14 days before harvest." "For control of quackgrass, Canada thistle, common milkweed, toadflax and dandelion; and season-long control of perennial sow thistle, Vantage can be applied prior to harvest of wheat, barley (including malting barley), oats, canola (rapeseed), flax (including low linolenic acid varieties), lentils, peas, dry beans, soybeans and forages. DO NOT apply to crops if grown for seed production." 

Roundup Proven to Cause Liver Disease - Recall Must be Enacted  (Moms Across America, Zen Honeycutt,  January 09, 2017)   January 9, 2016 a new study reveals that the weedkiller Roundup causes liver disease in rats after being exposed to doses lower than allowed by the EPA to be present on American food and feed crops. The story was published by Claire Robinson of GMWatch.

Monsanto Supporters Admit Massive Fail over Glyphosate Report Criticism (Sustainable Pulse, Nov 28 2016)  Read ful article for links and details. Fail #1: Criticism of testing methodsFolta was forced to withdraw his criticism, which he had already fed to a selection of journalists across the U.S. Fail #2: Misinformation regarding the safety of low levels of glyphosate. Modern independent science has discovered that many toxic chemicals have as much or more of an influence on our health at low doses– these chemicals are known as hormone hackers (endocrine disruptors). Glyphosate is likely to be one of these. Fail #3: Peer Review needed for food testing results? Dr. Folta and colleagues have now taken to stating that they cannot trust the results because they are not peer-reviewed, even though they are all clearly aware of the difference between University studies and commercial laboratory reports.This is a ridiculous line of attack as millions of food samples in the U.S. are tested and reported by FDA-registered laboratories, such as Anresco Laboratories, every single year with no peer-review. SNAP Comments: We may think they have failed but, as long as there are no obligatory endocrine effects for pesticide registration and people believe their BS, they are winning...

EPA Postpones Glyphosate Cancer Review Meeting after Letter from CropLife America (Beyond Pesticides, October 21, 2016)  Last week, the U.S. Environmental Protection Agency (EPA) postponed a long-planned Scientific Advisory Panel (SAP) on the carcinogenicity of the widely used herbicide glyphosate due to “recent changes in the availability of experts for the peer review panel.”  However, as veteran journalist, formerly with Reuters, Carey Gillam reports in the Huffington Post, the move was likely the result of a letter industry front group CropLife America sent to EPA just days before the postponement, challenging the bias of certain experts on the panel. Croplife America is a national trade association that represents manufacturers, formulators, and distributors of pesticides, and has a vested interest in tamping down consumer concerns over glyphosate’s carcinogenicity. SNAP comments: We should all be complaining about the perennial use of industry-sponsored experts on panels. CropLife, both in Canada and the US, acts like if their studies, mosty unpublished, are the only objective one,s while evidence has shown over and over again the industry-bias of industry-sponsored studies. 

Glyphosate: New monograph published  (GM watch,11 October 2016) 'PAN International says, "Adverse human impacts detailed in the review include acute poisoning, kidney and liver damage, imbalances in the intestinal microbiome and intestinal functioning, cancer, genotoxicity, endocrine disruption, reproductive and development reduction, neurological damage and immune system dysfunction.”' 'Glyphosate is sprayed on over 80% of GM crops and is used to “desiccate” other crops to make them easier to harvest.'The new review can be accessed here: http://pan-international.org/wp-content/uploads/Glyphosate-monograph.pdf

Another reason to NOT use gyphosate!

Glyphosate in Childhood Vaccines (Moms Across America, Sep 6, 2016)  DTap Adacel (Sanofi Pasteur) vaccine had 0.123 ppb, Influenza Fluvirin (Novaris)  0.331 ppb and HepB Energix-B (Glaxo Smith Kline) 0.325 and Pneumonoccal Vax Polyvalent Pneumovax 23, (Merck) had 0.107 ppb of glyphosate.The MMR II (Merck) vaccine, which CDC whistle blower Dr.William Thomas has linked to autism, had levels up to 25 times higher than the other vaccines, at 2.671ppb. Subsequently, multiple rounds of additional independent tests have confirmed these findings at or above the same levelsSNAP NOTE: Small amounts but injected, not eaten. Furthermore glyphosate is know to have negative health effects at low dose.

Glyphosate Causes Changes to DNA Function Resulting in Chronic Disease, According to Study (Global Justice Ecology Project, July 20, 2016 by GJEP staff}Another study on effects of glyphosate (RoundUp) this time looking at the mechanism of action. It is used instead of glycine in molecules in DNA, therefore preventing it from assuming the right shape for being used. I guess it prevents the puzzle pieces from fitting properly..."However, EPA indicated that much of the information provided may not impact their current risk assessment for glyphosate, which is expected sometime in 2017." SNAP note: Why not? It does not help that 'industry experts'... usually form the majority (or close to) of any risk assessment committee, it also seems that they EPA's main concern is not public health. I don't think the EPA or the Canadian PMRA have any ideas on how to handle questions outside the very inadequate 'regulatory testing'.

Glyphosate Sprayed on GMO Crops Linked to Lake Erie’s Toxic Algae Bloom (EcoWatch, Lorraine Chow, 5 July 2016)  "Through his own and others' research, Spiese found that depending on the types of metal in the soil, glyphosate does release phosphorus", and phosphorus is a known link to algi blooms. RoundUp ​is a phosphonoglycine type of chemical, meaning that it contains phosphorus (P). A lot of RoundUp used in the watershed is being detected in adjacent waterways particularly in the spring, 'The researchers also found that the blue-green algae (cyanobacteria) in the lake are capable of using phosophonates.'"It turns out that many cyanobacteria present in Lake Erie have the genes allowing the uptake of phosphonates, and these cyanobacteria can grow using glyphosate and other phosphonates as a sole source of phosphorus," Bullerjahn said.Also filed under water 

The Last Roundup: How the world's best-selling pesticide is heading for a fall (National ObserverBy Warren Bell in Opinion | July 4th 2016}  "Monsanto, like other large corporations, has had a special department established for this purpose (to ferociously attack any study, researcher or organization that threatens the corporation's products) for a long time." I always wondered how the scientific journal could retract the Seralinini study here it is ( with links): "By some as yet undisclosed means, a veteran Monsanto researcher, Richard E. Goodman – with a background in dairy science and immunology, but not plant science or pesticides – suddenly appeared out of nowhere on the senior editorial board of the journal that had published the Séralini paper, in a newly created position called “Associate Editor for biotechnology”."  Very well researched and great links. Warren Bell is a family physician who is Past Founding President of Canadian Association of Physicians for the Environment. also filed under  industry shenanigans.

Study Finds Low Levels of Roundup Cause Adverse Effects to Soil Health (Beyond Pesticides, May 13, 2016)  A study published last month shows that the chemical is toxic to soil fungus at doses well below levels which are recommended for agricultural use. The commercial formulation of Roundup is more toxic than technical active ingredient, glyphosatehighlighting the need to evaluate full formulation effects, including so-called inert ingredients. Not only does RoundUP kill some essential soil fungi at doses well below recommended application rates, but at lower concentration affects the soil fungus’ ability to break down nutrients for energy use. Inert ingredients are called formulants n Canada and are mostlystill secret.

The Real Reason Wheat Is Toxic (it’s Not The Gluten) Gluten may still be a problem as I think modern wheats contain a lot more than old wheats.I was made aware of RoundUp's use for 'pre-harvest' weed control several years ago. In Canada, this is legal, even though RoundUP is not registered as a dessicant. I have also noted many 'dessicated' wheat fields over the years. The tables are interesting. For health, buy organic. Warning if you are a wheat weaver from a friend who said you should avoid dessicated wheat because it breaks rather than weave properly. I have not tested this myself.

Long-term yield trends of insect-pollinated crops vary regionally and are linked to neonicotinoid use, landscape complexity, and availability of pollinators (Heikki M. T. Hokkanen et al,  Arthropod-Plant Interactions, June 2017, Volume 11, Issue 3, pp 449–461, First Online: 21 April 2017) a Finnish study. 'It appears that only the uptake of neonicotinoid insecticide seed dressing about 15 years ago can explain the crop yield declines in several provinces, and at the national level for turnip rapeseed, most likely via disruption of pollination services by wild pollinators.' 

A worldwide survey of neonicotinoids in honey   E. A. D. Mitchell1,2,* et al  (Science  06 Oct 2017: Vol. 358, Issue 6359, pp. 109-111)   We assessed the global exposure of pollinators to neonicotinoids by analyzing 198 honey samples from across the world. We found at least one of five tested compounds (acetamiprid, clothianidin, imidacloprid, thiacloprid, and thiamethoxam) in 75% of all samples, 45% of samples contained two or more of these compounds, and 10% contained four or five. 

Neonicotinoid Seed Coatings Create Exposure Hazards for Honey Bees and Fail to Increase Yields  (Beyond Pesticides, May 31, 2017) This article deals with corn and soy. In Saskatchewan, most of our canola is treated with neonics and U of S studies have shown widespread contamination of sloughs. “There was a misconception that any bees not living near corn were likely to be fine. But that’s not true, and it’s clear that these insecticides are reaching into the places bees forage and putting them at risk.” The research team set up neonic dust collection traps at 12 corn fields around Indiana and collected samples over two years to determine the levels of pesticide dust at increasing distances from the corn field edges. The data demonstrate the movement of neonic residues outside the borders of planted fields, and the researchers estimate that residues on non-target lands and waterways will be deposited on over 42% of the state of Indiana during the corn planting season." 

Common pesticide damages honey bee's ability to fly  (phys.org. April 26, 2017) 

Common pesticide damages honey bee's ability to fly (phys.org.

"Our results provide the first demonstration that field-realistic exposure to this pesticide alone, in otherwise healthy colonies, can alter the ability of bees to fly, specifically impairing flight distance, duration and velocity" said Tosi. "Honey bee survival depends on its ability to fly, because that's the only way they can collect food.

Report Documents Threats to Aquatic Life, Calls for Phase-Out of Neonicotinoid Use  (Beyond Pesticides, April 14, 2017) – As pollinators nationwide suffer severe declines tied to widespread exposure to pesticides, particularly a family of insecticides known as neonicotinoids, a new report details the chemicals’ dramatic impacts on aquatic ecosystems and biodiversity. This report coincides with findings of neonicotinoids in drinking water.The new report, Poisoned Waterwaysdocuments the persistence of neonicotinoids in U.S. waterbodies and the danger they cause to aquatic organisms, resulting in complex cascading impacts on aquatic food web. The report supports previous calls for the restriction of neonicotinoid pesticides, given their high toxicity to bees, and now aquatic life. Poisoned Waterways reviews the current scientific literature on the effects of neonicotinoids in waterways and the life they support. The report also highlights current regulatory failures of EPA aquatic standards, which continue to underestimate risks to sensitive species due to a reliance on test protocols that do not reflect real-world exposures or susceptibilities. Further, the impacts of chemical mixtures and synergistic interactions are not considered.

By Killing Beneficial Insects, Neonic-Coated Seeds Increase Pesticide Dependency, Just Like Other Insecticide Applications (Beyond Pesticides, December 16, 2016)  A new meta-analysis has challenged the belief that neonicotinoid (neonic) insecticide seed coatings have little to no effect on the health of beneficial predatory insect populations —on the contrary, researchers have found that the seed coatings impact predatory insects as much as broadcast applications of other insecticides...As predicted, the population of predatory insects are reduced in the plots where coated seeds are planted, compared to the plots that are untreated by insecticides. Additionally, the meta-analysis finds that coated seeds affected predatory insect populations similarly to soil and broadcast applications of pyrethroids.

Half of the Total Decline in Wild Bees throughout the UK Linked to Use of Neonics (Beyond Pesticides, August 18, 2016)  Decline of wild bee populations is linked to the use of toxic, systemic neonicotinoid (neonic) pesticides used on oilseed rape (canola), according to new research done by a team of scientists at the Centre for Ecology and Hydrology in the United Kingdom.The study, Impacts of neonicotinoid use on long-term population changes in wild bees in England, published in the journal Nature Communications, analyzed 18 years of UK national wild bee distribution data for 62 different species, and related it to amounts of neonicotinoid use. NOTE: Interesting for Saskatchewan as canola is a major user of neonic seed treatment.

Insecticides Similar to Nicotine Found in about Half of Sampled Streams across the United States 8/18/2015.U.S. Geological Survey.USGS discovered insecticides known as neonicotinoids in a little more than half of both urban and agricultural streams sampled across the United States and Puerto Rico, according to a study by the agency published today in Environmental Chemistry. “In the study, neonicotinoids occurred throughout the year in urban streams while pulses of neonicotinoids were typical in agricultural streams during crop planting season,” said USGS research chemist Michelle Hladik, the report’s lead author.

Neonicotinoids Hinder Bee’s Ability to Smell Flowers (Beyond Pesticides, June 29, 2015)...'a neonicotinoid pesticide, at sublethal doses, harms this odor memory formation,” Chinese Academy of Science’s Ken Tan, who led the study, told CBS News in an email interview.' 'Published in Nature on June 18, 2015, the study finds that “adults that ingested a single imidacloprid dose as low as 0.1 ng/bee had significantly reduced olfactory learning acquisition, which was 1.6-fold higher in control bees. Bees exposed as larvae to a total dose of 0.24 ng/bee had significantly impaired olfactory learning when tested as adults; control bees exhibited up to 4.8-fold better short-term learning acquisition.” Researchers conclude that this sublethal cognitive deficit caused by low dose exposure to neonicotinoids on a broad range of bee species is cause for further study. also published under Bee Die-off.

Sulfoxaflor and flupyradifurone: Neonicotinoids or not ?

view details »

Because of this detailed factsheet, articles about these 2 chemicals will be under the neonicotinoid section of this page from now on. This is an important distinction because, as neonicotinoids are shown to have such a massive effects on pollinators, companies want to keep on  registering insecticides with the same mode of action without the bad press of calling them neonicotinoids. France, which banned many neonicotinoids, has recently approved those two because the regulators have been fooled. There is currently (November 2017) a campaign to ask for France to 'Ban all bee-killing pesticides!' Please consider signing and sharing. 

Sulfoxaflor and flupyradifurone:  Neonicotinoids or not ? (PAN Europe, Sept 2016)

The pesticide industry is trying to hide the reality behind two new chemicals that are similar to the notorious group of neonicotinoids linked to massive bee death all over the world.
Their properties clearly show that they should be classified as neonicotinoids.

General conclusion
This factsheet has demonstrated how pesticide companies make use of pseudo-science to give their new pesticides a more positive image. In the frame of the ever greater interest of the general public in the relation between pesticide use and health damage, including bee health, the fact that pesticide companies themselves decide what category a pesticide belongs to, for mere regulatory or marketing purposes should not be authorised.
Sulfoxaflor and flupyradifurone are neonicotinoid insecticides. They should be treated accordingly by regulator, taking into account their systemicity and the harm they could cause to non-target organisms such as bees.


New Study Exposes Range of Harm from Neonicotinoid Pesticides (Beyond Pesticides, June 18, 2013)   Soil half-life of the most commonly used seed treatments can range from 200- 1000 days. Clothianidin has the potential to remain in soil for 6,931 days (nearly 19 years!) before degrading .“Studies from the US suggest that neonicotinoid seed dressings may be either entirely ineffective or cost more than the benefit in crop yield gained from their use. We seem to be in a situation where farmers are advised primarily by agronomists involved in selling them pesticides.” says Dr Gouslon.

Pesticide Factsheets (NCAP) These fact sheets detail health effects of pesticides. Not all pesticides on the market are coveredbecause so little independent research exists for most of them. The chemicals covered are (or were at the time of the writing) widely used with enough independent research.
