The aims of this project were to support the hay export industry by shortening the turnaround time for soaking the hay and testing extracts and by refining the standardisation of the ARGT ELISA, enabling us to revise the upper detection limit (cut-off) for hay that has tested negative for R. toxicus.
The results of this research have already benefited the hay export industry. The revised cut-off for hay that has tested ‘negative’ and the shortened extraction time have been approved by the Australian Quarantine and Inspection Service (AQIS) and were applied by the laboratories and the producers in the 2006 hay season. These improvements streamlined the extraction process at the hay producers’ premises and in the laboratories and the amended cut-off for negative hay allowed for the export of additional hay for the 2006 season to the value of approximately 1 million dollars.
