Agriculture committee begins hearings on biosecurity

Government officials say Canada is prepared for potential animal disease outbreaks, even though there were delays in dealing with some cases of avian influenza.

Speaking to MPs during the standing agriculture committee’s first meeting on animal biosecurity, chief veterinary officer Dr. Mary Jane Ireland said stringent safeguards are in place, including science-based import controls at the international border, to keep diseases out of the country.

Avian flu, however, likely arrived with migratory birds before domestic commercial flocks were affected.

Conservative agriculture critic John Barlow said he heard from farmers saying they were frustrated because the Canadian Food Inspection Agency was slow to respond. He said Canada had avian flu outbreaks in 2004 and 2014.

“You’re supposed to be on farms within 48 hours (and) we were hearing within 10 days in some cases,” he said. “Do you have the resources necessary to handle these outbreaks? Was there something that was unexpected with the most recent flu outbreak?”

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
