An H-E-B employee at the grocery store’s East Riverside location has tested positive for COVID-19, the company said Sunday afternoon.

The employee was last in the East Austin H-E-B Plus store on March 28, the company said. It said all other employees at that location have been notified and the store has undergone several deep cleans and sanitizations since that date. Employees at affected stores are also receiving medical advice from the company.

The announcement comes one day after the grocery store chain began equipping its employees with masks and gloves while at work. The store began that practice Saturday.

"While we understand the use of masks does not fully prevent the transmission of coronavirus, we are taking every precaution to ensure our partners feel comfortable while serving our customers," the company said.
