The September 2018 discovery of CWD on a managed operation in Grenville-sur-la-Rouge Quebec prompted a wholesale slaughter of 3500 animals in two months before the enterprise shut its doors for good. The CFIA ordered the cull, as well as the decontamination of 10 inches of soil in certain places on the 1000-acre operation. Post-discovery, each animal was tested for CWD by the CFIA before it was released onto the market. Other Quebec producers lamented the glut of supply. A 400 km quarantine area was declared, in which all hunting and trapping activities were banned. Government massacred hundreds of wild beasts over a two-month period. The routine cull for market was between 70 and 100 animals per week. When the producer was forced to close, the weekly slaughter neared 500 beasts per week. One year later, 750 wild specimens had been culled in the 45 km-radius "enhanced monitoring area", and none tested positive for CWD.
