Industrialized Animal Production—A Major Source of Nutrient and Microbial Pollution to Aquatic Ecosystems

  author={Michael A. Mallin and Lawrence B. Cahoon},
  journal={Population and Environment},
Livestock production has undergone massive industrialization in recent decades. Nationwide, millions of swine, poultry, and cattle are raised and fed in concentrated animal feeding operations (CAFOs) owned by large, vertically integrated producer corporations. The amount of nutrients (nitrogen and phosphorus) in animal manure produced by CAFOs is enormous. For example, on the North Carolina Coastal Plain alone an estimated 124,000 metric tons of nitrogen and 29,000 metric tons of phosphorus are… Expand

Industrial Swine and Poultry Production Causes Chronic Nutrient and Fecal Microbial Stream Pollution
Concentrated animal feeding operations (CAFOs) are the principal means of livestock production in the USA and Europe, and these industrial-scale facilities have a high potential to pollute nearbyExpand

How nutrient inputs—from fertilizer and CAFOs—as well as atmospheric NH3 and greenhouse gas emissions, are changing regionally within the US and how these changes compare with nutrient inputs from human wastewater is provided. Expand
Tracing nutrient pollution from industrialized animal production in a large coastal watershed
One of the highest concentrations of swine and poultry concentrated animal feeding operations (CAFOs) in North America is located on the Coastal Plain of North Carolina, in which the Cape Fear RiverExpand
Waste from livestock and poultry breeding and its potential assessment of biogas energy in rural China
Abstract Global livestock and poultry industry is growing continuously, with large amounts of excreta produced. These wastes could be either important anaerobic fermentation materials of biogasExpand
Waste nutrients from U.S. animal feeding operations: Regulations are inconsistent across states and inadequately assess nutrient export risk.
The federal guidelines for AFO nutrient management, focusing on swine, are summarized, and the regulations of four AFO-rich states in different regions of the USA are compared to identify inconsistencies among regulations and regulatory gaps. Expand
Manure Spills and Remediation Methods to Improve Water Quality
Within the last 2 decades the transition in livestock production technology and intensity has resulted in an increase in annual livestock production and a drastic decrease in the number of livestockExpand
Stimulation of fecal bacteria in ambient waters by experimental inputs of organic and inorganic phosphorus.
The finding of significant phosphorus stimulation of feces indicates that extraneous nutrient loading can, at times, augment the impacts of fecal microbial pollution of shellfishing and human contact waters. Expand
Agro-Industrial Wastewater Pollution in Greek River Ecosystems
In this chapter, the characteristics and environmental impacts of wastewaters from the major agricultural industries on the river ecosystems of Greece are reviewed and discussed, focusing especiallyExpand
Season matters when sampling streams for swine CAFO waste pollution impacts.
Seasonal data showed significantly higher concentrations of conductivity, nitrate, total nitrogen, total organic carbon, and fecal bacteria in summer as opposed to early spring, so sampling performed only in winter-early spring would significantly underestimate impacts from swine CAFO spray fields on nearby waterways.

Potential geographic distribution of atmospheric nitrogen deposition from intensive livestock production in North Carolina, USA.
Observed regional patterns of reduced nitrogen deposition can be largely explained by two factors: limited atmospheric transport distance, and spatial aggregation of CAFOs. Expand


Management and utilization of poultry wastes.
Waste by-products such as excreta or bedding material that are generated by the worldwide annual production of poultry meat and 600 billion eggs are generally land applied as the final step of a producer's waste management strategy. Expand
Nitrogen and Phosphorus Imports to the Cape Fear and Neuse River Basins To Support Intensive Livestock Production
Feeds imported to support rapidly expanding intensive livestock operations (ILOs) in North Carolina represent significant quantities and proportions of “new” nutrients in local watersheds. The CapeExpand
Agriculture and urban activities are major sources of phosphorus and nitrogen to aquatic ecosystems. Atmospheric deposition further contributes as a source of N. These nonpoint inputs of nutrientsExpand

Tracing nitrate transport and environmental impact from intensive swine farming using delta nitrogen-15.
This study shows that riparian buffers are not always adequate to prevent discharge of concentrated nitrate in ground water from commercial swine farms in the Mid-Atlantic Coastal Plain, and that additional measures are required to ensure non-discharge conditions. Expand
Bacterial Pollution from Agricultural Sources: A Review
T potential for environmental contamination through the indiscriminate handling of agricultural wastes has been a topic of intensive research during the past two decades. The potential for diseaseExpand
Regulation of estuarine primary production by watershed rainfall and river flow
Enhanced phytoplankton production and algal blooms, symptoms of eutrophication, are frequently caused by elevated nutrient loading, usually a s nitrogen, to coastal waters. This nitrogen is derivedExpand
Pathogens in livestock waste, their potential for movement through soil and environmental pollution
This review highlights some of the many factors that are likely to influence the degree of pollution by their effect on both the vertical and horizontal transport of microorganisms through soil. Expand
