Development of a Cost-Effective Treatment Process for Removing Antimicrobials from Agricultural Wastewater

Much of the antimicrobials (AM) used therapeutically and prophylactically pass through the animal and enter the environment through irrigation with beef runoff wastewater (WW).  There are concerns repeated low-level AM loading of soils through irrigation will alter the natural biota resulting in increased resistance; thereby, making AM critical for human and animal health less effective.

Ciprofloxacin residues in biosolids compost do not selectively enrich populations of resistant bacteria

Biosolids and livestock manure are valuable high-carbon soil amendments, but they commonly contain antibiotic residues that might persist after land application. While composting reduces the concentration of extractable antibiotics in these materials, if the starting concentration is sufficiently high then remaining residues could impact microbial communities in the compost and soil to which these materials are applied.…

Antibiotic Losses during Thermophilic Composting

Purpose

Residual antibiotics in land-applied manure and biosolids present a potential threat to public and ecological health, so it is important to determine antibiotic removal efficiencies for manure and biosolids waste management practices and to identify conditions that enhance antibiotic degradation.…

Antibiotic Resistance and Animal Agriculture

This webcast examines the veterinary feed directive and how it impacts animal agriculture as well as discusses the state of the science as it relates to antibiotic resistance. Finally, it busts some myths and reviews “facts” to keep in mind when chatting with livestock producers and the general public.This…
