Mr. Chair, I'd simply say I did make reference to a couple of studies. My own assessment is that although there have been a couple of important studies done in this field, which have yielded results which would suggest that relative to the general population there is a significant issue in agriculture, my impression of the literature is that this is not an area that has been exhaustively studied and that there very likely is scope for further research to better inform efforts to target resources.
