Olymel temporarily closes Alberta pork plant because of COVID-19 outbreak Gil McGowan is making the demand a day after Olymel indefinitely closed its pork plant in central Alberta, which has been linked to hundreds of virus cases and the death of one worker.He says he aims to remind the United Conservative government that its job is to protect the public and not the profits of corporations.A statement from the labour group links to a letter that Alberta Health Services wrote to Olymel last week, which says on-site testing suggests one in five workers may have been infected.The letter also says about 60 per cent of Olymel staff hold at least one other job outside the plant and those other employers must be notified of positive cases.
