Hepatitis E virus and coliphages in waters proximal to swine concentrated animal feeding operations.
North Carolina is the second leading state in pork production in the United States, with over 10 million swine. Swine manure in NC is typically collected and stored in open-pit lagoons before the liquid waste is sprayed onto agricultural fields for disposal. Components of this waste may be able to impact surface water quality with the potential for human exposure. This study examined viruses of...
متن کاملAntibiotic-Resistant Enterococci and Fecal Indicators in Surface Water and Groundwater Impacted by a Concentrated Swine Feeding Operation
BACKGROUND The nontherapeutic use of antibiotics in swine feed can select for antibiotic resistance in swine enteric bacteria. Leaking swine waste storage pits and the land-application of swine manure can result in the dispersion of resistant bacteria to water sources. However, there are few data comparing levels of resistant bacteria in swine manure-impacted water sources versus unaffected sou...
متن کاملImpacts of Waste from Concentrated Animal Feeding Operations on Water Quality
Waste from agricultural livestock operations has been a long-standing concern with respect to contamination of water resources, particularly in terms of nutrient pollution. However, the recent growth of concentrated animal feeding operations (CAFOs) presents a greater risk to water quality because of both the increased volume of waste and to contaminants that may be present (e.g., antibiotics a...
متن کاملPigs in Space: Determining the Environmental Justice Landscape of Swine Concentrated Animal Feeding Operations (CAFOs) in Iowa
Given the primacy of Iowa in pork production for the U.S. and global markets, we sought to understand if the same relationship with traditional environmental justice (EJ) variables such as low income and minority populations observed in other concentrated animal feeding operation (CAFO) studies exists in the relationship with swine CAFO densities in Iowa. We examined the potential for spatial c...
متن کاملReducing concentrated animal feeding operations permitting requirements.
Many owners and operators of concentrated animal feeding operations (CAFO) need to secure National Pollutant Discharge Elimination System permits from the federal or state permitting authority. Because of the expense and inconvenience of permit applications, farm groups have challenged revisions to the federal CAFO Rule as well as state regulations claiming selected provisions exceeded the auth...
