A shop in Co Down closed after members of staff tested positive for coronavirus.
The Barbican SuperValu in Newcastle posted the information in a message on their Facebook page on Monday.
It announced the shop was closed after a “handful of colleagues” tested positive for Covid-19.
However it is set to reopen on Tuesday morning following a professional deep clean.
“As a result, we made the decision to close the store this morning so that we could fully investigate and contact all colleagues,” the shop posted on Facebook.
“As per HSC guidelines, contact tracing has taken place and some of our colleagues are now in self-isolation for 14 days.
“The health of our colleagues and customers is our top priority and in line with guidance from health experts, the store is undergoing a professional deep clean as a precautionary measure and will reopen at 6am tomorrow morning.
“If you have been in store and are concerned, please contact the NHS 111 helpline service.”
