Does that mean 125% of the gm maize rats got cancer?

I'll just file this report with the others showing deformities in Belarus children and using shock photos blaming fallout from Chernobyl.
In other words, in my voluminous Bull Shyte folder.

Act against what? The pesticide or that strain of GM corn?

Something's not quite right with this study. Hundreds of millions of thousands of animals have been fed GM produce by farmers with no ill effect so far.

The genuine point of concern is how this paper got through peer review.

It shows some of the criticism of this study comng from the scientific community.

Some include that this rate line has a tendencey to develop tumors anyway, no adequate control, and poor use of statistics.

Moreover the rats in the study were being fed Roundup pesticide in adition to the GM maize.

The same scientific community that is telling us that drinking fluorinated water is good for our health. :rolleyes:

As opposed to the CT community who tell us the world is controlled by Jewish lizard aliens, yes I'll believe the scientists thanks.

So what were te results for the group that was fed the GM grains without the weedkiller added?
Just out of curiosity, really.

Thanks for posting that, it does provide a good deal more information than the panic-mongering article previously referred to.

I find this bit the most telling :

Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn.

While there certainly are more aspects to this than a layperson such as myself would be able to grasp easily, it does sound a lot like they were mostly poisoned. Which seems to be more likely to be due to the weed killer than due to the genertic alterations of the food.

The paper is behind a paywall so I can't read it. However I'll try and get it.

I'm getting my information from New Scientist. A good article here.

"But didn't the treated rats get sicker than the untreated rats?
Some did, but that's not the fully story. It wasn't that rats fed GM maize or herbicide got tumours, and the control rats did not. Five of the 20 control rats – 25 per cent – got tumours and died, while 60 per cent in "some test groups" that ate GM maize died. Some other test groups, however, were healthier than the controls."

If by bias you mean that peer review should ensure that only well wriiten papers with sound, repeatable experimental methodologies are published than yes. Yes, it "doesn't fit into [my] bias".

According to this, there was no control group who got fed GM maize without weed killer residue.

So, all that study does show is that in sufficiently high concentration, weed killer isn't healthy for rats.

Well, paint me pink and call me surprised! Who'd have thought?

"find this bit the most telling"

That "weed killer" are two Bt toxins used as insecticides produced by the maize itself due to genetic manipulation by Monsanto. Maybe you read the study before you're citing it and drawing false conclusions.

What? Why would the plant produce a weed killer? The plant is resistant to the weed killer. They are used in combination.

"NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation."

Have you actually read it? Be honest now.
Roundup is a weedkiller you can buy in B&Q.

Are you just stupid or are you intentionally lying here?

Please READ:

"Furthermore, groups of animals were also fed with diets containing one of six other normal (non-GM) reference maize lines"

2.2. Plants, diets and chemicals

The varieties of maize used in this study were the R-tolerant NK603 (Monsanto Corp., USA), and its nearest isogenic non-transgenic control. These two types of maize were grown under similar normal conditions, in the same location, spaced at a sufficient distance to avoid cross-contamination. The genetic nature, as well as the purity of the GM seeds and harvested material, was confirmed by qPCR analysis of DNA samples. One field of NK603 was treated with R at 3 L ha−1 (WeatherMAX, 540 g/L of glyphosate, EPA Reg. 524-537), and another field of NK603 was not treated with R. Corns were harvested when the moisture content was less than 30% and were dried at a temperature below 30 °C. From these three cultivations of maize, laboratory rat chow was made based on the standard diet A04 (Safe, France). The dry rat feed was made to contain 11, 22 or 33% of GM maize, cultivated either with or without R, or 33% of the non-transgenic control line. The concentrations of the transgene were confirmed in the three doses of each diet by qPCR. All feed formulations consisted in balanced diets, chemically measured as substantially equivalent except for the transgene, with no contaminating pesticides over standard limits. All secondary metabolites cannot be known and measured in the composition. However we have measured isoflavones and phenolic acids including ferulic acid by standard HPLC-UV. All reagents used were of analytical grade. The herbicide diluted in the drinking water was the commercial formulation of R (GT Plus, 450 g/L of glyphosate, approval 2020448, Monsanto, Belgium). Herbicides levels were assessed by glyphosate measurements in the different dilutions by mass spectrometry.
2.3. Animals and treatments

Virgin albino Sprague-Dawley rats at 5 weeks of age were obtained from Harlan (Gannat, France). All animals were kept in polycarbonate cages (820 cm2, Genestil, France) with two animals of the same sex per cage. The litter (Toplit classic, Safe, France) was replaced twice weekly. The animals were maintained at 22 ± 3 °C under controlled humidity (45–65%) and air purity with a 12 h-light/dark cycle, with free access to food and water. The location of each cage within the experimental room was regularly moved. This 2 year life-long experiment was conducted in a GPL environment according to OECD guidelines. After 20 days of acclimatization, 100 male and 100 female animals were randomly assigned on a weight basis into 10 equivalent groups. For each sex, one control group had access to plain water and standard diet from the closest isogenic non-transgenic maize control; six groups were fed with 11, 22 and 33% of GM NK603 maize either treated or not with R. The final three groups were fed with the control diet and had access to water supplemented with respectively 1.1 × 10−8% of R (0.1 ppb of R or 50 ng/L of glyphosate, the contaminating level of some regular tap waters), 0.09% of R (400 mg/kg, US MRL of glyphosate in some GM feed) and 0.5% of R (2.25 g/L, half of the minimal agricultural working dilution). This was changed weekly. Twice weekly monitoring allowed careful observation and palpation of animals, recording of clinical signs, measurement of any tumors that may arise, food and water consumption, and individual body weights.
