Workers are self-isolating at the Herefordshire farm

A further 19 workers have tested positive for coronavirus on a farm which went into lockdown.

Vegetable producers A S Green and Co in Herefordshire ordered crop-pickers to self-isolate after 74 tested positive.

Herefordshire Council and Public Health England (PHE) said the number of cases had now risen to 93.

Two groups of workers who arrived in the UK via bus and plane - including some who worked at A S Green - are being traced as a precaution.

In a joint statement, the council and PHE said those who tested positive were not showing symptoms when they travelled to the UK.

They have begun contact tracing with a group of workers who travelled into the UK by private coach, including some who went on to work at A S Green and Co.

Authorities in Scotland have been notified about a group of 63 workers on the same flight who travelled to Scottish farms, the statement said.

No cases have been identified among a further 76 workers on the flight who went on to other farms in England.

Three workers, including one who had tested positive for Covid-19, have been traced after they left the site against health officials' advice.

All are said to be self-isolating.

On Wednesday, Herefordshire Council said a fourth worker who tested negative for the virus had also left the site. They are also said to be self-isolating.

About 200 workers are in quarantine at the site's live-in accommodation, and others are being tested, the council said.

Karen Wright, Director of Public Health for Herefordshire, said: "We continue to test workers at the farm and expect to see the number of cases rise over the coming days before social distancing and infection prevention measures start to take effect.

"We're aware that local residents are concerned, but the risk to the general public remains low."
