The fast-food outlet has shutdown 12 restaurants for deep cleaning after a truck driver tested positive for coronavirus.
The external service provider had made deliveries to the restaurants and interacted with a small number of employees.
A spokesperson for the company said the driver was asymptomatic and unaware they had contracted COVID-19.
They said the restaurants had been closed in an “abundance of caution”.
“The Department of Health has identified the truck driver as a workplace close contact of the previously announced Craigieburn COVID-19 case,” they said.
“McDonald’s Australia has taken this significant action in the best interests of the health and safety of our employees and our customers.
“We will open each of the restaurants following completion of the deep clean and pending the availability of replacement crew.”
Potential close contacts and employees who worked shifts during and after the truck drivers’ delivery have been told not to return to work for 14 days and advised to be tested.
No other employees have tested positive so far.
