A group of farm workers in Scotland have been quarantined after they were on the same flight as people who travelled to a coronavirus-hit farm
Vegetable producer A S Green and Co in England went into lockdown after tests showed 93 people had tested positive for Covid-19.
Some of them were on a flight bringing agricultural workers to the UK which included 63 people heading to Scotland.
Testing has been made available to them and none has shown Covid symptoms.
The Scottish government said officials in Scotland were alerted by Public Health England.
A spokesperson said: "A number of farm workers in Scotland travelled to the UK at the same time as those in Herefordshire.
"All those farm workers are understood to have undertaken the required 14-day quarantine on the farms where they are based and have exhibited no symptoms in that time.
"The risk of infection is understood to be very low in this case, however testing is being made available to all those working on these farms."
It is understood two farms in Scotland were affected, but their location has not been revealed.
Precautionary action
The A S Green farm in Mathon, Herefordshire, employs a mix of seasonal workers from the UK and abroad and they have been asked to quarantine at the site's live-in accommodation.
Three workers who left the farm against health advice, one of whom had tested positive for Covid-19, have now been traced and are self isolating.
Katie Spence, Public Health England's Midlands health protection director, said: "Information gathered from both the recruitment company and from the workers themselves suggested that those workers who tested positive were not showing any symptoms of Covid-19 at the time they travelled to the UK.
"We know, however, that there is a risk that people can transmit the infection before - or without ever - developing symptoms, and this is why we've taken a precautionary approach to follow-up workers who were on the same flight as the confirmed cases."
