The Seralini glyphosate study republished

Study republished in Environmental Sciences Europe. Critics of the study claimed the rats Seralini used were a special rat already prone to tumors. 'The known high incidence of tumours in the Sprague–Dawley strain of rat ”cannot be excluded as the cause of the higher mortality and incidence observed in the treated groups”, [statement from Elsevier] added.' It's common in research to have special rats or mice with certain weaknesses, to study how things affect them. But in this case, the choice of rat strain was probably inappropriate.(Search for info on Sprague Dawley rats.)

The journal that originally published the paper³, Food and Chemical Toxicology (FCT), retracted it in a storm of criticism in November 2013 after Séralini’s team refused to withdraw it (see ‘Study linking GM maize to rat tumours is retracted’). A post-publication review of the paper found that “the data were inconclusive, and therefore the conclusions described in the article were unreliable.” However FCT found “no evidence of fraud or intentional misrepresentation of the data”, according to the journal's publisher, Elsevier in Amsterdam.

Séralini's team had found that rats fed for two years with a glyphosate-resistant type of maize (corn) made by Monsanto developed many more tumours and died earlier than did control animals. It also found that the rats developed tumours when Roundup was added to their drinking water.

The issue with Roundup-resistant foods is that the Roundup label says the foods can be harvested 2 days after spraying. Surely this means some Roundup gets into foods. Roundup booklet pdf here.

If Roundup is so safe

1. Why do they require you to wear shoes and socks? (Booklet PDF page 1, right column, under Precautionary Statements, then Personal Protective Equipment).
2. Why does the Roundup booklet from Monsanto say this: "Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet." (PDF page 1)
3. And why this? "Remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing."
4. Why this warning? "Keep and wash PPE (Personal Protective Equipment) separately from other clothing." 
5. And on page 2: "Do not apply directly to water, or in areas where water is present, to intertidal areas below the high water mark. Do not contaminate water when cleaning equipment or disposing of equipment wash waters." But studies showed it was safe in water!
6. Still on page 2, left column, right below Non Agricultural Use Requirements: "Potatoes grown for seed are very sensitive to glyphosphate at extremely low concentrations. Exposure of the seed potato crop can cause germination failure or deformities."
