In this study, Spanish researchers examined 76 samples of organic and conventional beef, chicken, and lamb for 33 carcinogenic pollutants that are commonly found in non-organic meat. As expected, pesticides were found in the non-organic samples.
The surprising finding came from the organic samples – not only were none of the samples free from contaminants, but the difference in levels of pollutants between the organic and conventional samples was very minimal.
Of the samples, they found that lamb – both non-organic and organic – had the highest level of pesticides of all the samples. In fact, the organic samples actually containing more pollutants than the non-organic!
