Stop & Shop services may be impacted after a cybersecurity issue was detected within its parent company’s U.S. network.

On Friday, Stop & Shop’s parent company, Ahold Delhaize USA, announced that it had launched an investigation into the breach. The company is working with external cybersecurity experts and law enforcement to “assess and mitigate the issue.”

While all Stop & Shop locations remain open, some services, including certain brands, pharmacy offerings, and e-commerce operations, may be affected as the company has taken some systems offline to protect them.

“We will continue to take actions to further protect our systems. The security of our customers, associates and partners is a top priority. We apologize for any inconvenience this issue may have caused customers and partners,” Ahold Delhaize USA said in a statement.
