I'll endeavour to answer your question.
Although I'm not the expert for disease control and animal health, certainly with the outbreak of PED in Ontario and other provinces, the CFIA has worked very closely with provincial partners, with the United States authorities as well, to investigate the source of the disease, including possible linkages to feed supply.
Our work with partners is continuing. We are working with other experts in Canada and around the world to get a better understanding of the disease and how it affects livestock, and what type of remedial measures and corrective actions would be required in the future. It is a work in progress.
