There is currently one active case in Warrnambool and no active cases in Corangamite, Glenelg, Moyne and Southern Grampians shires.

No new cases of coronavirus were recorded in regional Victoria in the past 24 hours as the total number of active cases in regional local government areas dropped by four to 43.

The latest data comes after Victorian Premier Daniel Andrews announced regional Victoria would enter step three of the roadmap to 'COVID Normal' on Wednesday at 11.59pm.

Update, 1.50pm: Bulla Dairy Foods has recommenced full production at its Connor Street site in Colac after an outbreak at the workplace led to 20 coronavirus infections.

Employees returned to work after receiving final clearance from the Department of Health and Human Services and following a deep clean of the entire site finalised last Friday September 11.

The site reopened Saturday September 12 and full production commenced yesterday 6am.

The 244 employees had to quarantine for 14 days after the DHHS identified them as 'close contacts' of an employee who tested positive to COVID-19 late August.

They all returned negative tests, said chief executive Allan Hood.

There are still seven infected Bulla employees who are self-isolating.

"It has been a positive start to the week for the Bulla family following final clearance from the DHHS to reopen our Connor Street, Colac site," he said.

"The health and safety of our team, and the wider community in which we operate, is of utmost importance to us and we have worked closely with the DHHS and relevant authorities to take all necessary steps to ensure the workplace is COVID-19 safe for the return of our team.

"Moving forward, we continue to focus on creating a safe environment across all Bulla sites by adhering to all government and health authority's advice as well as ensuring we are all following strict hygiene and safety protocols we have put in place, including those additional measures implemented in the last two weeks.

"As we head into the warmer months and the Christmas period, we are pleased to be able to support our local community even further and are now recruiting team members to join the safe and supportive home of Australia's favourite ice cream to help us ensure that Bulla's real dairy frozen treats are widely available on shelves and freezers around the country.

"Lastly, our seven team members who have received positive COVID-19 test results are still recovering at home in isolation and we are pleased to share that they have indicated to us that they are feeling much better. We will continue to support them on their journey to recovery."

Mr Hood had criticised the health department last week after it linked 16 cases to Bulla Dairy Foods in Colac.

A DHHS spokesperson told The Standard today there are currently 20 cases linked to the facility including 13 active cases.

"The department is working closely with Bulla Dairy Foods, Barwon Health and Colac Health to contain a coronavirus outbreak at the Bulla Dairy Foods Colac facility," he said.

"The facility has been deep cleaned and all staff have been tested and close contacts will be required to isolate for 14 days.

"The facility recently reopened with reduced staff and Bulla has been working very closely with the department to manage this process to ensure the safety of all staff."

He said DHHS was closely monitoring the outbreak and is in regular contact with the Bulla Dairy Foods operations manager through regular Incident Management Team meetings.

He said that by grouping cases together into a single outbreak, the public health team can ensure it is identifying and investigating any possible links in transmission within a connected community and mitigate these.

There are cases in Colac unrelated to the Bulla Dairy outbreak and these are not included in the Bulla total.

All organisation based outbreaks totals include contacts as well as employees/residents/staff/students of that location/business.

Mr Hood said some stock had been lost due to the closure of the icream production at Connor Street.

"When our Connor Street site was temporarily closed from 30 August, we were able to move the stock we had to our other sites across Victoria to ensure there was no wastage.

"Due to the required 14-day closure at our Connor St site there has been some impact on the production and supply of our frozen ranges."
