A burger venue which has not yet opened to the public has been forced to carry out deep cleaning after a staff member tested positive to coronavirus.
Betty's Burgers had been due to open in the Canberra Centre on July 13.
However a staff member was one of the three people in Canberra to test positive to the virus on Wednesday. The staff member was last in the restaurant on Monday.
The restaurant is now undergoing deep cleaning with high-grade disinfectant.
Contact tracing is underway, with ACT Health reaching out to people who may have been exposed to the virus.
A spokeswoman for Betty's Burgers said the opening of the restaurant would be delayed as a result.
"We can confirm one of the current COVID-19 cases in the ACT is a team member at Betty's Burgers Canberra," she said.
"The restaurant is in the final stages of construction and is not open to the public. We are providing our full cooperation with ACT Health.
"The site was immediately closed and team members and construction workers informed of the requirement to self-isolate.
"A full deep clean of the store is being coordinated. Our focus is on working to ensure the wellbeing of our team and the broader community and no date has been set for the opening of the store."
An ACT Health spokeswoman said there was no wider risk to Canberra Centre staff based on their investigation.
"As mentioned in today's update, ACT Health is working with a small number of close contacts that have been identified and are being managed in accordance with National Guidelines," she said.
"Our expert contact tracing team do appropriate exposure risk assessments, in line with the National Guidelines, and follow up with close contacts as required.
"All close contacts of these individual cases are being followed up. The public is notified if there is a potential risk to public health."
Previously, ACT chief health officer Dr Kerryn Coleman said the positive cases had visited the Fyshwick markets on Saturday and Westfield Belconnen on Monday. It is not clear why the Canberra Centre was not mentioned.
Canberra Centre general manager Gary Stewart said the centre took the case extremely seriously.
"Canberra Centre and the tenant are working closely with ACT Health and are following their advice in how to respond to this matter," Mr Stewart said.
"This includes taking steps to understand who may have been in recent contact with the person who tested positive so ACT Health can do contact tracing, along with undertaking a deep clean of the tenancy with high-grade disinfectant."
The Canberra Centre had already stepped up its cleaning rotations in response to the pandemic.
It is frequently cleaning commonly touched areas like hand railings and door handles with a high-grade disinfectant.
"Canberra Centre remains open and trading, serving the everyday and essential needs of our local community," Mr Stewart said.
"We encourage anyone that is feeling unwell and suspects they may have symptoms of COVID-19 to self-isolate and seek medical attention as soon as possible."
