The interest in veterinary pharmaceuticals as potential emerging contaminants has stemmed from the proliferation of large-scale animal feeding operations (AFOs) during the last decade. The large number of animals produced creates a proportionately large volume of animal waste and associated emerging contaminants; initial efforts for this study have focused on veterinary antibiotics. In a reconnaissance study of liquid waste at swine AFOs in Iowa and North Carolina, multiple classes of antibiotics were detected ranging from ppb to ppm concentrations. Compilation of data from liquid waste from swine operations between 1998 to 2002 found one or more antibiotics present in all of the samples. Antibiotics also have been detected in poultry litter from the Delmarva Peninsula. The data from these studies demonstrate that veterinary pharmaceuticals are excreted and frequently occur at detectable levels ranging from ppb to ppm concentrations in liquid and solid waste. Some of this research has been conducted in collaboration with the Centers for Disease Control.
