254 Controlling Bugs & Drugs

Oral Session
ASA Section: Environmental Quality
Manure-borne pharmaceuticals, pathogenic microorganisms and antibiotic-resistant bacteria are an ongoing challenge in animal production.  The microbial and chemical composition of manure, dynamics of contaminants during manure storage or treatment, and subsequent fate in the agricultural environment depend upon numerous production, environmental and soil management factors.  This session will consider recent and future developments in animal production and manure treatment practices that will help mitigate the environmental and human health risk from the ‘Bugs & Drugs’ carried in manure.
