Coupar Angus chicken factory workers to 'self isolate until August 31st' after urgent advice update
The new guidance also includes children in those households and anyone who has had a negative test.
Anyone living in a household with a factory worker from a food processing plant in Coupar Angus has been told to isolate at home until Monday August 31, NHS Tayside has said.
First Minister Nicola Sturgeon described the 43 positive cases identified so far, as part of an outbreak at the 2 Sisters food processing plant, as "a significant cluster''.
Of those cases 37 are factory workers and six are contacts.
The new guidance, which also includes children in those households and anyone who has had a negative test, has been issued after a meeting of the incident management team which is working with the Scottish Government.
Dr Emma Fletcher, NHS Tayside associate director of public health, said: "This is a critical change to our advice this evening.
"We are putting in place this extra measure to help prevent further spread of the infection in the community.
"It's also really important that everyone in the Tayside area is extra vigilant in following the Facts guidance, in particular the over 70s, and those who were shielding or in high-risk groups.
"A large proportion of the workforce has already come forward for testing which is excellent but we would strongly encourage all workers who have not yet been tested to take up this offer, even if they don't have any symptoms.
"We continue to work closely with the factory and Local Authority colleagues to ensure that all workers have the right information and support to access testing.''
It comes as Ms Sturgeon again urged caution amid the growing number of coronavirus clusters and new cases across the country.
During her latest coronavirus update at Holyrood, Ms Sturgeon said the cluster is "reflected in the fact that 27 of today's 77 cases are in the Tayside area''.
Elsewhere in that health board area, eight adults at Kingspark School in Dundee have tested positive and the city council has temporarily closed the site.
Paul Clancy, Dundee City Council executive director, said: The city council and NHS Tayside continue to work together on thorough investigations.
"All staff can get access to testing. We will advise families as soon as we can about when Kingspark will reopen.
"Keeping pupils and staff save is our paramount concern.''
Ms Sturgeon also said Scotland is now recording 52 new cases of Covid-19 a day on average, compared to just 14 at the time of her last lockdown review three weeks ago.
Other clusters involve schools in the central belt with 16 cases in north-east Glasgow, linked to Bannerman High School, and a "separate but linked cluster'' of nine cases in Coatbridge.
NHS Lanarkshire has previously said pupils from St Ambrose and St Andrew's High in Coatbridge had tested positive.
There were also 12 new cases in NHS Grampian on Wednesday, bringing the total identified in the health board are to 407 since July 26 - 237 of them associated with the cluster linked to Aberdeen pubs.
Despite those numbers, Ms Sturgeon said progress is being made in Aberdeen and a further review of the local lockdown is to come this weekend.
She told the Scottish Parliament: "There is evidence that the original cluster of cases linked to Aberdeen pubs is coming under control, but in recent days we have continued to see new cases which do not seem to be linked to that first cluster.
"Because of that, restrictions in Aberdeen have been extended, but will be reviewed again on Sunday, with a view to setting out, if possible, a firm timetable for lifting the restrictions.
"All of these outbreaks are being tackled by our test and protect teams, and current evidence on their performance suggests that the vast majority of contacts are being identified, and most are being identified quickly.
"However, the clusters and new cases highlight a continued need for caution, especially since our priority continues to be to keep schools open.''
She added: "These clusters are not completely unexpected.
"We have always known that reopening more services and premises, especially indoor bars, restaurants and cafes, might lead to an increase in cases.
"And indeed two major risk factors have stood out in reports of recent clusters.
"As we expected, indoor hospitality, bars and restaurants, is one.
"The other is social events and gatherings in people's homes.
"We have already tightened some of the rules in relation to the indoor hospitality sector, for example by putting guidance on a statutory footing, and making it compulsory to collect customers' contact data.''
