The Purpose of our study was really to answer the question: what are the health benefits and harms of organic versus conventional foods? There are many reasons why someone might choose to buy organic foods or not , and if, if they are making that decision based principally on a belief about the health benefits, I would say that there is not a robust evidence base to suggest that that would be the case. But that doesn't mean that they might not choose to buy organic foods for other reasons, like concerns about the environment, pesticide use in general, the way that animals are cared for. We found 30% lower risk of contamination with pesticides in organic produce compared to conventional fruits and vegetables; however, the levels of pesticide residues in those foods were well below the national safety limits. We found no differences in bacterial contamination between organic and conventional foods. However, we did find that the bacteria contaminating chicken and pork were 33% less likely to be resistant to multiple antibiotics. Certainly, I do buy organic produce, and I do so on the basis of some of my other concerns, but certainly, now after this study, really, you know, I don't do it because of any, sort of personal health concerns.
