A LOCAL lockdown down will only happen 'if necessary' said the First Minister following concerns after more than 150 workers tested positive for coronavirus at a poultry plant.

Following the conclusion of the rapid screening phase for Novel Coronavirus (COVID-19) among employees associated with the 2 Sisters Food Group poultry processing plant in Llangefni, Public Health Wales has - to date - identified a total of 158 positive cases.

Speaking today during the Welsh Government's daily coronavirus briefing, Mark Drakeford said: "We have held a meeting already today to review what is happening on the island of Anglesey.

"The outbreak has been in a closed setting.

"The success of our test, trace, protect system means we will be able to keep on top of on whether there is anymore general spread from the closed setting of the factory into the wider community and that system has been working very well over this weekend.

"We are working as well with the Joint Biosecurity sector which is producing templates that we will be able to draw on as to how you assess whether a local outbreak has taken place and what actions you would take if you concluded there was a need re-impose restrictions that had otherwise been lifted.

"There will be no delay, but our approach will be proportionate and draw on the evidence.

"It will draw on local intelligence and information and then we will take the action required."

In terms of how serious conversations were concerning a 'local lockdown', Mr Drakeford said: "Of course they are serious because the outbreak has been very serious.

"However, it has been an outbreak in a closed setting.

"Our test track and trace system has been able to successfully identify and trace the people in that setting.

"You have got to be proportionate, decisions restricting people's liberties should not be taken lightly.

"We won't take those actions unless we know that they are necessary."
