CAFOs and Public Health

There are several chemical and biological compounds found in livestock manure that can be toxic to humans in high concentrations. As such, there are concerns that the manure generated by CAFOs could have a negative impact on the public health of the surrounding community.  Specific concerns include: the effects of unabsorbed antibiotics and hormones, the development of antibiotic resistance associated with including antibiotics in the feed, the effects of emissions on the health of neighbors, and the fate of pathogenic microorganisms such as E. coli and Salmonella. You can learn more about each of these issues by following the links below. You can also submit to us any question that you feel is not already addressed through the “Ask an Expert” link to the left and we will have it answered by a well-informed professional.
