When a second case was confirmed on Sunday, the restaurant closed and the Health Department worked with the fast-food franchisee to conduct contact tracing and deep cleaning of the restaurant.
The Health Department said there was no risk customers were exposed to infection through food or food packaging handled by the sick workers but urged customers to get tested if they experienced coronavirus symptoms.
“There is no evidence COVID-19 can be transmitted to people through food or packaging, and the risk of anyone visiting the McDonalds contracting the virus is very low,” a department spokesman said.
Seventeen new cases were recorded in Victoria in the 24 hours to Tuesday afternoon.
Eight of the confirmed cases were linked to a Cedar Meats, including six staff and two close contacts, taking the total number of cases in the cluster to 85.
Three were three cases of community transmission with no known link to another confirmed case.
About 258,000 tests have been completed, with 13,000 of those carried out on Monday. The government is hoping to conduct another 150,000 tests by the end of the month.
