Conestoga Meats is closing for a week after seven workers tested positive for COVID-19. There may be more as testing continues.
The Waterloo Region Health Unit and the Ontario Ministry of Labour have launched investigations.
"Employees have expressed concerns regarding COiVID-19 positive cases at the plant," said president Arnold Drung.
"The health, safety and wellbeing of Conestoga Meats employees is our priority."
In the statement, Drung says limited staffing and operations will be maintained. He said employees will be compensated for their time off.
The health unit expects more positive cases will turn up, given the size of the staff which is about 1,000 workers.
