The main objective of the research is to assess the costs and other consequences of potential measures to control pathogens associated with all stages of livestock manure management. Pathogen control measures in place or under consideration in the UK and other countries will be reviewed, and their pathogen reduction potential will be assessed. The possible effects of implementing these measures will be determined for different livestock productions systems (i.e. dairy, beef, pigs, poultry, sheep and organic), for both liquid and solid manures, throughtout the wholl manure management continuum. The range of effects considered will include: implications of changes to manure management systems, changes in soil fertility and cropping patterns, knock-on effects for other sectors, environmental impacts, including interactions with other government policies on the environment (e.g. NVZs and IPPC). For each pathogen control measure and livestock production system combionation, the costs to the farming industry will be estimated, and the practicality and applicability of implementing the measurements assessed. The results will be presented as a ranking matrix taking into account their cost-effectiveness, practicality, applicability and environmental impact. Gaps in knowledge and priorities for further research will also be identified.
Results of the research will provide scientific underpining to MAFF policies that promote the recycling of livestock manures to agricultural land as the most economic, practical and environmentally beneficial mangement option in most cases, whilst protecting public health in relation to food and to animal disease transmission to humans.
