Newcastle shop staff test positive for Covid-19
A number of workers at a supermarket in Newcastle, County Down, have tested positive for Covid-19.
The BBC understands four members of staff at the Barbican SuperValu in the seaside town contracted the virus.
Musgrave, which operates the store, said those affected were following medical advice and were in self-isolation.
Contact tracing has also taken place and any close-contact individuals have been informed, the firm added.
The shop was closed for most of Monday and has undergone a deep clean. It will reopen on Tuesday.
Musgrave said there had been a "handful of confirmed cases of Covid-19".
"If any customers who have been in store are worried or concerned, we would ask them to contact NHS 111 helpline service," the company added.
