Opinion:CFIA should heed science, as it always claims to do

The Canadian Food Inspection Agency’s livestock transport regulations appear to be a compromise between science and popular opinion.

In fact, the agency has said as much.

CFIA’s new policy requires the offloading of cattle for eight hours after 36 hours of travel. But another federal government department has research that contradicts the need for weaned or fat calves — the ones most likely to see longer rides — to be unloaded, fed, watered, rested and reloaded.

Three scientific studies by Agriculture Canada have concluded that the above-noted CFIA regulation brings no benefit. The science suggests that offloading and reloading delays arrival with little to no benefit for the cattle, potentially increasing the risk of injury and threatening biosecurity.

Domestically, cattle moving to and from Alberta or Saskatchewan and Ontario would be the most likely loads affected by the new rules. Stops in Thunder Bay are now required to meet regulations and investments have been made there to accommodate the added livestock traffic.

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.
