    Abstract

    The use of poultry waste as a fertiliser on arable land is an accepted method of waste treatment. However, run-off from such practices may result in contamination of the watercourse by human pathogens. In this study the effectiveness of using constructed wetlands as an alternative treatment for poultry manure waste was evaluated. Enumeration of Campylobacter spp., Escherichia coli , total coliforms and total aerobes were carried out on influent and effluent samples from reed beds loaded with poultry waste. For both sequential loading and continuous loading there was a statistically significant mean log reduction of 3.56 and 4.25 for E. coli , 3.2 and 3.88 for coliforms, 3.85 and 4.2 for total aerobic counts and 3.13 and 2.96 for Campylobacter spp., respectively. This method, which has been previously recognised as cost-effective and environmentally acceptable, provides an efficient method for reducing numbers of these bacteria in poultry waste and therefore an effective alternative treatment for such waste or waters containing run off from land previously spread with poultry manure.
