Nassly Sales and Sid Mukherjee ordered two boxes of diapers from the online retailer one marked “new” and the second described as “used: like new,” according to The Jersey Journal Friday. The description noted that the packaging was damaged, but original. The couple noted that they order diapers from the online retailer every two months.

Sales said she felt the box was heavier than usual, and then was hit with a gross scent when she opened the box with her husband. “I picked up the pack to kind of take a closer look [and] that’s when the stench hit me,” Mukherjee told The Jersey Journal.

Mukherjee said the box smelled like urine and noted that one diaper actually had feces in it. He said that he couldn’t help but laugh at the situation. Sales said she noticed the diapers were soiled after she put the lights on.

Upon discovering the soiled diapers, Sales called the Centers for Disease Control and had the couple’s 19-month-old daughter checked out by a doctor, who said she’s healthy.
