Several studies in 2019 suggest that organic systems are better at suppressing foodborne pathogens like E.coli. For example, research published in the journal Biological Control found that one way organic farms suppress pathogens is by supporting biodiversity that directly prevents pathogens. Researchers surveyed beetle communities in conventional and organic farms, and found that only organic farms fostered the right beetle species that directly suppresses E. coli on farms. Another study in Frontiers in Microbiology looked at bacteria on food once it got to the grocery store and found that organic fruit may harbor fewer bacterial diseases than their conventional counterparts.
