A comprehensive carcinogenicity study on the world's most used herbicide, glyphosate, involving scientists from Europe and the U.S., has found that low doses of the controversial weed killer cause multiple types of cancer in rats.
In this long-term study, glyphosate alone and two commercial glyphosate-based formulations, Roundup BioFlow used in the EU and Ranger Pro used in the U.S., were administered to rats via drinking water beginning in prenatal life, at doses of 0.5, 5, and 50 mg/kg body weight/day for 2 years.
These doses are currently considered safe by regulatory agencies and correspond to the EU Acceptable Daily Intake (ADI) and the EU's No Observed Adverse Effect Level (NOAEL) for glyphosate.
In all three treatment groups, increased incidences of benign and malignant tumors at multiple anatomic sites were observed compared to controls. These tumors arose in hemolymphoreticular tissues (leukemia), skin, liver, thyroid, nervous system, ovary, mammary gland, adrenal glands, kidney, urinary bladder, bone, endocrine pancreas, uterus and spleen (hemangiosarcoma).
Increased incidences occurred in both sexes. Most of these involved tumors that are rare in Sprague Dawley rats (background incidence < 1%) with 40% of leukemias deaths in the treated groups occurring in early life and increased early deaths were also observed for other solid tumors.
"We observed early onset and early mortality for a number of rare malignant cancers, including leukemia, liver, ovary and nervous system tumors. Notably, approximately half of the deaths from leukemia seen in the glyphosate and GBHs treatment groups occurred at less than one year of age, comparable to less than 35–40 years of age in humans.
"By contrast, no case of leukemia was observed in the first year of age in more than 1,600 Sprague Dawley historical controls in carcinogenicity studies conducted by the National Toxicology Program (NTP)," stated Dr. Daniele Mandrioli.

The freon game I knew about.
Interesting post.
Unfortunately all the alternatives suck if you want to kill weeds for a long time.
Also,
Whatever we substitute is likely to have similar health risks.
The bottom line is that we “want” (convenience) and in part “need” (prevent crop destruction at an affordable cost point) some of these substances.
To me, these articles serve as a precaution when using (where, how much, avoid skin contact or inhalation), use only when necessary, as little as needed to get the job done, wash vegetables and fruit from the grocery store before consuming... At home substitute safer options when possible.
I don’t freak out about it, but I also avoid unnecessary exposure.
But who am I to talk, I’ve had cancer twice. I might not be the best to give advice. LOL
That's because it's a lot more work: huge monoculture fields must be broken up into strips interspersed with bug resistant crops, crop rotation instead of fertilizers, etc.
A pre-modern agriculture can only support a pre-modern population. A return to pre-industrial methods would mean a return to working class Americans paying 40-50% of income for food, as was common in the early 20th century.
That’s a good point.
However, I was thinking along the lines of your house garden when I made my comment. Many people spray instead using natural remedies where they can.
For example, I was reading some time ago that you can create the richest garden imaginable if you dig up your garden and remove the dirt. Then interlace carbon and dirt when you put it all back.
I carefully follow ALL the application rules and keep meticulous records of when, where and how much I applied.
I have a 5 acre “Gentleman’s farm” in Hawaii. lots of animals and things live here.
The generic roundup, I use works great. Outlaw that chemical and I’d use Diesel.
My grandfather built a couple of raised beds behind his house in upstate NY: 8 foot tall trellises full of tomatoes, squash, etc. The whole family would go to collect the surplus and can every summer. It was incredible, but very labor intensive.
The current refrigerant transition is a long-running train wreck over the last couple years. The industry and most especially the regulators have not handled it well at all.
No dioxin in roundup.. it’s the big nasty in agent orange.
My grandfather was quite the gardener as well. He was known for leaving baskets of garden vegetables at the end of his driveway for people to take at will.
One of his tricks was, each spring, he would get in a little rowboat on Lac La Nonne and fish up a catfish. He would then rototill into the soil before he started planting his garden.
He was one of the few farmers in his area that was able to protect his farm from drought during the Great Depression.
Up to 50 mg/ kg is considered safe? 2500 to 5000 mg, 2.5 to 5 grams per day is safe ( adult size)?
Maybe this has something to do with the rise in bowel cancer in the young. The widespread use of glyphosate as grain crop dessicants. Spray right before harvest.
So how do they grow crops in Europe?
Everything has it’s costs. Use that vinegar based weed killer recipe and you’ll start turning your soil more acidic. Mine in my garden is too acidic for many veggies to to begin with, so then I have to do even more correction.
Then again, almost no veggies (seeds or starter plants) that I can obtain are resistant to ANY weed killer besides me pulling up the weeds without disrupting the desired plants.
Obviously that latter does not apply to modern (ie., cost effective) farming techniques.
Well, at least one of the opossums that has been digging up the garden got a lead pellet in the head earlier tonight. (He made the mistake of going over by the chicken house and alarming them, which alerted me...) I’ll behead and gut him tomorrow, boil him in mild salt water, and turn him back over to the chickens. This will make them very happy.
TANSTAAFL.
if you keep soil covered you have much less weeds for a season or more.
Todays’ problem also is generations of people who bought into the thinking and ways of “farming” big fields. This “on demand” food addiction we live in, is what’s killing many people (obesity, diabetes, cancers etc) and the land (over worked so add lab made fertilizers etc)
Mass production is not normal in nature, it happens slowly, but people want to mess with the natural ways of how the world was designed to run, so we create our selves more problems and disease etc.
All the big farm tilling is the main cause of weeds in their fields. If they didnt till so often or deeply they wouldn’t keep stirring up weed seeds to germinate. Less weeds would deter some insect pests who like those weeds.
For crop loving insect problems they could easily use extra natural things like pheromone traps, repellents etc. hot pepper powder, blood or bone meal, essential oils.
mulch of some sort (leaves, seedless grass and weeds, plastic type weed fabric, cardboard) anything to cover the soil and you have much less weeds.
But these more natural ways don’t make big money for pesticide companies and big machine makers, genetic modifiers of seed etc etc etc
the modifiers have lessened the nutrients of crops, grow shorter/faster to harvest, and other things only to the detriment of the human body consuming them.
suggestion: grow your own or connect with a small scale natural grower and buy from them what’s in season, and thank God for His abundant blessings.
The product sold as “ROUNDUP” has in fact changed its recipe. No more is gylophsphate or however it is spelled, used. I don’t think the stuff works as good anymore. Had to mulch weeds instead. That works two ways- kills weeds AND increases root moisture.
I have a great respect for Joel Salitan’s method of farming... it is actually a method of animal husbandry that does not disrupt the land.
I have a friend who farms and others who garden using permaculture techniques that are chemical free.
Natural strategies, like summer fallow. Which was purposely leaving a crop land dormant for one year where it would be cultivated a couple times for weed control. Crop rotation was important too.
Now it’s plant every square inch with whatever sells the best and use chemicals for fertilizing and weed control.
Long term use of these chemicals will certainly have negative effects down the road.
What’s worse then round-up?
Adults who call vegetables veggies and veg.
We will achieve idiocracy.
In Vitro Testing
Researchers have created “organs-on-chips” that contain human cells grown in a state-of-the-art system to mimic the structure and function of human organs and organ systems. The chips can be used instead of animals in disease research, drug testing, and toxicity testing and have been shown to replicate human physiology, diseases, and drug responses more accurately than crude animal experiments do.
Some companies, such as AlveoliX, MIMETAS, and Emulate, Inc., have already turned these chips into products that other researchers can use in place of animals.
A variety of cell-based tests and tissue models can be used to assess the safety of drugs, chemicals, cosmetics, and consumer products. For example, MatTek Life Sciences’ EpiDerm™ Tissue Model is a 3-dimensional, human cell–derived model that can be used to replace rabbits in painful, prolonged experiments that have traditionally been used to evaluate chemicals for their ability to corrode or irritate the skin.
The PETA International Science Consortium Ltd. helped fund the development of MatTek Life Sciences’ EpiAlveolar, a first-of-its-kind 3-dimensional model of the deepest part of the human lung. The model, composed of human cells, can be used to study the effects of inhaling different kinds of chemicals, pathogens, and (e-)cigarette smoke.
Devices made by German-based manufacturer VITROCELL are used to expose human lung cells in a dish to chemicals in order to test the health effects of inhaled substances. Every day, humans inhale numerous chemicals—some intentionally (such as cigarette smoke) and some inadvertently (such as pesticides). Using the VITROCELL machines, human cells are exposed to the airborne chemical on one side while receiving nutrients from a blood-like liquid on the other—mimicking what actually occurs when a chemical enters a human lung. These devices, as well as EpiAlveolar, can replace the current method of confining rats to tiny tubes and forcing them to inhale toxic substances for hours before they are eventually killed.

Considering how much Round Up is used on so many foods these days, there’s no knowing how close to that toxic threshold any one of us are getting.
That’s one major reason I grow my own, aside from the fact that I enjoy gardening.
