Some consumers pay more for organic food because they believe it is safer than conventionally grown produce. But according to an article by Marc Morano of CNS News.com, a new study shows that organic foods may contain a significantly higher risk of fecal contamination. The study, conducted at the University of Minnesota, found organic produce had nearly 10% positive samples of E. coli bacteria, compared to only one and a half percent for conventional produce. In addition, salmonella was found only on organic samples. But this only makes sense, since organic farms often rely on composted animal manure, instead of chemical fertilizers.
