Market Basket announced Friday that an employee at its distribution center in Andover, Massachusetts, has tested positive for the COVID-19.
The company said some other workers were concerned with heading into the facility to go to work on Friday morning.
"We consider it our responsibility to continue to take the aggressive steps necessary to protect our associates and also to make sure they understand the precautions they need to take to best protect themselves," Market Basket spokesperson Justine Griffin said in a statement.
Market Basket had previously taken steps to secure its stores in the region by limiting the number of customers allowed in at one time and making all aisles "one-way" lanes.
Employees who came into contact with the worker who tested positive have been identified and sent home from work for a 14-day quarantine.
