Nachman KE, Lam J, Schinasi LH, Smith TC, Feingold BJ, Casey JA. O'Connor et al. systematic review regarding animal feeding operations and public health: critical flaws may compromise conclusions. Syst Rev. 2017;6(1):179.
In this comment, we summarize several scientific concerns with the recently published systematic review from O'Connor and colleagues that examined the relationship between proximity to animal-feeding operations and health of individuals in nearby communities. The authors utilized a bias tool not designed for environmental health research, erroneously excluded important studies, and incorrectly interpreted others. As a result, the conclusions drawn in the review misrepresent the evidence from the published literature, limiting its value to policymakers, researchers, and the public.
