The rolled OATS product in the picture was not among those tested – it  simply represents the category of oats products.


Lawrenceville, NJ (Dr Simone) – The International Agency for Research on Cancer classifies the active ingredient in Monsanto’s RoundUp, glyphosate, as “probably carcinogenic to humans.”  And the Environmental Working Group (EWG) has found high levels of it in some oat cereals, oatmeal, granola and snack bars.  45 oat foods were tested: 31 had higher than EWG’s acceptable, 12 had lower.  The highest levels were detected in two samples of Quaker Old Fashioned Oats and in Cheerios.  Glyphosate was also found at detectable concentrations in five of 16 organic oat food samples. 1 to 2 year old children have the highest risk.  Hydration is important if you eat oat food often because glyphosate is metabolized very quickly and eliminated in the urine.

Glyphosate is used to kill weeds and also to kill the mature crops of wheat, barley, oats and beans that are not genetically engineered. This forces drying and earlier harvest.

The US Right to Know organization forced the Food and Drug Administration to reveal their assessment.  The FDA found “a fair amount” of glyphosate in several processed foods.
