Epidemiology of VTEC 0157 and other VTECs likely to be pathogenic to man in farm wastes - OZ0709

Description

Objectives
• To review current waste management systems used on cattle farms in the context of the epidemiology of VTEC O157
• To develop validated laboratory and on-farm environmental sampling protocols to enable the recovery and enumeration of VTEC from various environmental samples
• To conduct field studies on cattle farms to determine the relative roles of different farm waste pools to the maintenance of VTEC within the farm environment
• To use the quantitative field data in farm simulation and risk-based models to evaluate the relative roles of different farm wastes in the maintenance and transmission of VTEC on farms
• To identify control points designed to reduce the environmental contamination by VTEC and to recommend interventions to be evaluated

Policy relevance
• Zoonotic potential of VTEC O157 and protection of public health
• Recent identification of the relative importance of VTEC O157 infection from the environment
• The need for field data on which to base advice for farm waste management

Intended use of results
• Results will be used to guide policy and to identify control points at which farm waste management methods may be adapted to reduce the environmental load of VTEC. These will require testing by intervention study to determine their efficacy

Objective
01 Review of cattle farm waste management practices in the context of the epidemiology of VTEC O157 (31 July 2002)
02 Design environmental sampling strategy for the recovery of VTEC from cattle farm wastes (28 February 2003)
03 Environmental farm-based longitudinal study of VTEC in cattle farm wastes (30 October 2004)
04 Development of mathematical and risk models to evaluate the role of different farm wastes in the maintenance and epidemiology of VTEC on cattle farms (31 December 2004)
05 Recommendations to reduce environmental contamination with VTEC (31 March 2005)
