Coronavirus: Australian McDonald's franchises close after delivery driver tests positive for COVID-19

McDonald's has closed restaurants across the Australian state of Victoria until further notice, after a delivery driver tested positive for COVID-19.

A dozen restaurants have been shut as the fast-food giant conducts a deep clean of the affected stores.

"The truck driver made deliveries to 12 restaurants and interacted with a small number of restaurant employees on each occasion while asymptomatic and unaware they had contracted COVID-19," a McDonald's spokesperson told 7 News.

McDonald's is assuring that customers are at "very low risk".

Chief executive of McDonald's Australia Andrew Gregory told 3AW radio host Neil Mitchell the franchise decided to close on Sunday.

"We confirmed that he [the truck driver] had tested positive. We then worked out the restaurants that he had made deliveries to, and immediately agreed with the franchisees to close those 12 restaurants," he said.

Gregory said the truck driver was tested after being identified as a close contact of another COVID-19 cluster.

He told 3AW it could be several days before the restaurants are reopened.
