Size‐based regulation and water quality: Evidence from the Iowa hog industry

American Journal of Agricultural Economics, EarlyView.
Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...

Stored swine manure and swine faeces as reservoirs of antibiotic resistance genes [PDF]

Letters in Applied Microbiology, 2013
Inclusion of low levels of antibiotics in the feed of domestic food animals promotes improved growth, animal performance and overall health benefits. However, this practice has come under scrutiny due to concerns over such feeding on bacterial antibiotic resistance (AR) and potential impact on human health.
