Narellan Town Centre has advised retailers that their stores should undergo a deep clean after a confirmed COVID-19 case visited the centre on July 6.
NSW Health confirmed that the individual who tested positive for the virus visited multiple stores in the centre throughout the day.
In a memorandum to shopkeepers throughout the centre, management said the centre itself would undergo a deep clean overnight and shops would remain open.
Dart West group general manager Brad Page told the Advertiser that the centre had been taking all precautions to ensure the safety of workers and customers.
"We are following the advice of NSW Health and following our Covid safe plan which is already in place in the centre," he said.
The centre has asked all employers to ensure any staff members experiencing flu-like symptoms self-isolate and get tested for the virus.
