RED DEER, Alta. — Alberta Health Services says it is responding directly to a COVID-19 outbreak that has infected hundreds at a hog slaughterhouse where almost two-thirds of workers have at least one other job outside the plant. Spokeswoman Heather Kipling said Tuesday nurses and contact tracers with experience in communicable disease control are helping manage the outbreak at Olymel's pork plant in Red Deer, Alta. The health agency is also arranging for ongoing testing to monitor for asymptomatic spread. Alberta Health has been notified of 343 cases linked to this outbreak. Of these, 200 are active, 142 recovered. One worker has died. Olymel said late Monday it was shutting down the hog slaughtering, cutting and deboning plant indefinitely because it believed it could no longer be operated safely and efficiently.
