M03022: Review of current slaughtering methods for cattle and sheep that avoid risk of dissemination of brain particles into blood and carcass, and maintain good welfare and operator safety standards
Wednesday 25 June 2003
This research project aims to evaluate existing and novel stunning methods used for stunning cattle and sheep with regard to animal welfare, public health and operator safety.
Background
One aim of the Agency's TSE programme is to establish the extent and risk of carcass contamination at slaughter and during carcass dressing. Since the confirmation of a link between BSE and vCJD there has been concern about the current stunning methods in cattle. This study will investigate the current situation and the alternative possibilities for stunning cattle and sheep.
Research Approach
A critical review will be conducted of existing and novel stunning methods, including published and unpublished evidence, on the efficacy of non-penetrating equipment used for stunning cattle and sheep with regard to animal welfare, public health and operator safety. There will also be a Technical Seminar organised for representatives of all stakeholders to facilitate discussion and reach conclusions on recommended practices and possible requirements for improvements.
Results and findings
A critical review of existing and novel stunning methods was carried out. This review considered the efficacy of non-penetrating captive bolt and other non-invasive techniques. A Technical Seminar was held at which representatives of all stakeholders met and discussed their recommendations of stunning practices and possible requirements for improvements. Preliminary conclusions suggest that non-penetrating bolts can present animal welfare and food hygiene problems. Electrical stunning of cattle and sheep can be effective but is also expensive. There are also some novel approaches that might offer potential after further research and development.
