Trader Joe’s has temporarily closed five stores after a number of employees showed symptoms and tested positive for the coronavirus. The grocery chain made the announcement on Wednesday, saying that it was taking precautions to clean and sanitize its stores.

The affected stores include locations in Millburn, New Jersey, Elkridge, Maryland; two stores in New York City; and two stores in Plainview, New York.

The company said that the stores will reopen when they have been fully cleaned and restocked.

Trader Joe’s said in a statement that it will continue to pay workers for their scheduled shifts during the closures and has recommended employees to follow self-monitoring guidelines if they came in contact with an infected worker.

“We are working closely with local health officials to take all necessary measures and provide our communities with the most appropriate information needed to make an informed decision regarding their health and safety,” the company said.

Trader Joe’s has modified its stores hours to be open from 9 a.m. to 7 p.m. daily with senior hours dedicated from 9 a.m. to 10 p.m. each day.
