EPA allows toxic levels of glyphosate in food.

US EPA hikes glyphosate limits in food and feed - again
GMWatch, 3 May 2013

In obedience to a demand from Monsanto, the US EPA is proposing to hike the allowed residue limits -- yet again -- of the herbicide glyphosate in various food and feed crops. The allowed level in teff animal feed will be 100 parts per million (ppm); and in oilseed crops, 40 ppm. Allowed levels in some fruits and vegetables eaten by humans will also rise.

As a comparison, malformations in frog and chicken embryos were documented by Prof Andres Carrasco's team at 2.03 ppm glyphosate, when injected into the embryos.

EPA is accepting comments on its latest move until 1 July.

The EPA's move comes shortly after the release of a study showing that glyphosate inhibits the growth of beneficial gut bacteria and leads to the overgrowth of pathogenic bacteria. Glyphosate concentrations at 0.1 mg/ml were found to inhibit growth of E. faecalis bacteria. E faecalis suppresses a bacterium called C. botulinum, which is responsible for botulism in cattle. The same concentration of glyphosate did not inhibit growth of C. botulinum. Some poultry and cattle feed samples in Germany were found to have 0.4–0.9 mg glyphosate/kg.

The findings suggest that glyphosate residues in feed may explain the increase in botulism seen in cattle in recent years.

Conclusion: there's never been a better time to eat organic - and to object on animal welfare grounds to the UK supermarkets' decision to allow GM animal feed into their supply chains.

TAKE ACTION: Tell the supermarkets what you think
