Glyphosate is a broad-spectrum
herbicide, currently with the highest
production volumes of all herbicides.
It is used in more than 750 diff erent
products for agriculture, forestry,
urban, and home applications. Its
use has increased sharply with the
development of genetically modifi ed
glyphosate-resistant crop varieties.
Glyphosate has been detected in air
during spraying, in water, and in food.
There was limited evidence in humans
for the carcinogenicity of glyphosate.
Case-control studies of occupational
exposure in the USA,14 Canada,6 and
Sweden7 reported increased risks
for non-Hodgkin lymphoma that
persisted after adjustment for other
pesticides. The AHS cohort did not
show a signifi cantly increased risk
of non-Hodgkin lymphoma. In male
CD-1 mice, glyphosate induced a
positive trend in the incidence of a
rare tumour, renal tubule carcinoma. A
second study reported a positive trend
for haemangiosarcoma in male mice.15
Glyphosate increased pancreatic
islet-cell adenoma in male rats in two
studies. A glyphosate formulation
promoted skin tumours in an
initiation-promotion study in mice.
Glyphosate has been detected in
the blood and urine of agricultural
workers, indicating absorption.
Soil microbes degrade glyphosate
to aminomethylphosphoric acid
(AMPA). Blood AMPA detection
after poisonings suggests intestinal
micro bial metabolism in humans.
Glyphosate and glyphosate formulations
induced DNA and chromosomal
damage in mammals, and in human
and animal cells in vitro. One study
reported increases in blood markers of
chromosomal damage (micronuclei) in
residents of several communities after
spraying of glyphosate formulations.16
Bacterial mutagenesis tests were
negative. Glyphosate, glyphosate
formulations, and AMPA induced
oxidative stress in rodents and in
vitro. The Working Group classifi ed
glyphosate as “probably carcinogenic
to humans” (Group 2A).
We declare no competing interests.

Glyphosate is a broad-spectrum
There’s growing concern about the use of antibiotics in the animal industry and agriculture.
Australia imports about 7 hundred tonnes of antibiotics annually. More than half of that goes into stock-feed, about 8% is for veterinary use, leaving only one-third for human use.
Antibiotics are used widely in food animals as growth promoters and to prevent and treat infection. Avoparcin, a glycopeptide related to the human last line drug Vancomycin, is used in Australia as a growth promotant in pigs, chickens and feedlot cattle. Virginiamycin is used as a growth promotant but also for treating resistant human bacteria.
As well as oral administration and injection of antibiotics, small amounts are mixed into animal feed for weeks or months at a time. Feed dosing provides ripe conditions for the emergence of resistant strains.
Antibiotics are also sprayed onto fruit trees to prevent and treat infection. Traces of antibiotics that remain after the initial spraying may encourage emergence of resistant strains of bacteria. During spraying the wind can spread low concentrations of the antibiotic further afield, possibly increasing the risk of resistant bacteria. In both cases, it is possible for antibiotic resistant bacteria to enter the food chain, ultimately reaching humans.
Antibiotic-resistant bacteria are slated to become a more common cause of death than cancer by 2050 worldwide, according to a new study sponsored by the British government.
“Antimicrobial Resistance: Tackling a Crisis for the Health and Wealth of Nations”was issued by the Review on Antimicrobial Resistance on Thursday. It combines data from two models that mostly concern stats on E. coli, malaria, and TB infections. It also notes that areas with high malaria, HIV, and TB rates are likely to suffer the most from the effects of these bacteria. India, Nigeria, Indonesia, and Russia are probably the countries most at risk, the report said.
According to a statement from Jim O’Neill, the economist who is chairing the review, “Drug-resistant infections already kill hundreds of thousands a year globally, and by 2050 that figure could be more than 10 million.” Cancer killed 8.2 million people in 2012, the most recent year with complete data. It’s worth noting that cancer deaths, at least in the United States, have declined by 20 percent since 1991 according to the American Cancer Society.

Regrowth of ‘jumpseed’, 3 weeks after being sprayed with glyphosate.
The red legged pademelon is now on its way for an autopsy. Now that I have sighted 2 more, with similar skin eruptions, it is vital we learn what is causing this obviously very painful condition.
This little fella came to my feet briefly hours before I found its body- a hard moment or two for me – should I end its suffering ? I remembered the simplified Hippocratic oath a doctor quoted to me once, that he was there to do no harm to me, his patient. Fortunately its suffering ended a short time later.
Attended the land-care meeting. Hubris from the herbicide supporters blurred any meaningful discussion on the concerns from those who have genuine worries as to the safety of glyphosate injection into coral trees on the creeks edge. When a presenter said that the the growing evidence from independent scientists is hocus pocus, when they present peer reviewed evidence in opposition to the chemical labels on herbicides, serious doubt follows as to the motives.
But if the many phone and e-mail response I am having since the meeting is any-thing to go by, serious concern is growing.
Unusual for this time of the year, 3 snakes are moving around the gardens. One quite thin. Keeping the hens in their pen, the two young ones are a nice size snack. The next photo shows the scar along the snake, perhaps a whipper snipper injury ?
A pilot study of American mothers’ milk has found levels of the herbicide glyphosate around 1,000 times higher than allowed in European drinking water. Campaigners are demanding a ban on the use of glyphosate on food crops.
What we are now looking at with glyphosate-based herbicides is a similar situation to what we all faced in the 20th Century with PCBs, DDT and Agent Orange.
In the first ever testing on glyphosate herbicide in the breast milk of American women, Moms Across America and Sustainable Pulse have found ‘high’ levels in three out of the ten samples tested.
The shocking results point to glyphosate levels building up in women’s bodies over a period of time, which has until now been refuted by both global regulatory authorities and the biotech industry.
This alarming article on Round-up was in my gmail box this morning. Thank-you Anette in the US.
The case for the ban on glyphosate.
The carcinogenicity of glyphosate is among the latest avalanche of damning evidence that makes a ban on glyphosate all the more compelling. Sri Lanka is the second country in the world to ban glyphosate after El Salvador.
Having rejected GMOs back in 2003, it has now banned glyphosate on the strength of a study by Sri Lanka’s own scientists implicating glyphosate in an epidemic of deadly chronic kidney disease that has struck Sri Lanka and other poor farming countries (see Sri Lanka Bans Glyphosate for Deadly Kidney Disease Epidemic, SiS 62).
Glyphosate is already implicated in the marked deterioration of the health status of the US population. The incidence of numerous diseases and adverse conditions has gone up in parallel with the increase in GM crops and the use of glyphosate herbicide since 1994 – the first year of commercialization of GM crops.
Perhaps we will be the last country to ban glyphosate, but we will get there.
Brazil’s federal public prosecutor has requested that the Justice Department immediately suspend use of glyphosate, which is the most widely used herbicide in the country and a primary element of Monsanto’s Roundup herbicide brand.

Because our media neglects to report anything other than economic “progress ” out of China, have a look at this article from Vice.
Glyphosate is one of the most widely applied herbicides globally but its persistence in seawater has not been reported. Here we quantify the biodegradation of glyphosate using standard “simulation” flask tests with native bacterial populations and coastal seawater from the Great Barrier Reef. The half-life for glyphosate at 25 °C in low-light was 47 days, extending to 267 days in the dark at 25 °C and 315 days in the dark at 31 °C, which is the longest persistence reported for this herbicide. AMPA, the microbial transformation product of glyphosate, was detected under all conditions, confirming that degradation was mediated by the native microbial community. This study demonstrates glyphosate is moderately persistent in the marine water under low light conditions and is highly persistent in the dark. Little degradation would be expected during flood plumes in the tropics, which could potentially deliver dissolved and sediment-bound glyphosate far from shore.
http://www.globalresearch.ca/index.php?context=va&aid=29684 Most of us, who live close to the ground, know by observation ( and how I wish I had time to closely monitor on paper what I see ) that there is a considerable reduction in numbers within insects, bird and butterflies populations. Climate change will be playing a huge part but the increasing use of round-up in this Shire will also be contributing.
