After a 12-hour day at work Wednesday, Nassly Sales got back to her Pearsall Avenue home and grabbed one of two boxes of diapers delivered by Amazon on Sunday to change her 19-month-old daughter before bed.

Sales, 42, picked up the box and found it to be heavier than usual. But when she and her husband, Sid Mukherjee, opened it they were met with a foul-scented surprise.

“I picked up the pack to kind of take a closer look (and) that’s when the stench hit me,” Mukherjee said, noting the pack of diapers smelled like urine before they realized they had been used. “Oh! This is not right ... one actually has poop in it.”

Mukherjee, 50, said he found himself incredulously laughing at the situation, adding that they order diapers for their daughter off Amazon at least every two months.

“I turned on the lights and that’s when I noticed that it was soiled,” Sales said. “I’m still in disbelief, to be honest.”

Of the two boxes of diapers that were purchased, one box’s condition was described as “new” and the second was described as “Used: like new.” The description said the packaging was original, but that it was damaged.

“We work hard to provide customers with a great experience and deeply regret that this situation did not live up to our high standards,” an Amazon spokesperson said in a revised statement Saturday morning after The Jersey Journal posted the story online. “We worked directly with the customer to address this situation.”

Mukherjee called Amazon’s customer service to inform them about the soggy, soiled package. Sales said it seemed like they couldn’t grasp what the parents were telling them, as the Amazon supervisor remained nonchalant about the situation.

Initially, the supervisor asked that the package to be returned, but then told Mukherjee “as a courtesy we are allowing you to keep the item,” Sales said. The gift card that the parents used to purchase the diapers was refunded, they said.

After discovering the urine and feces, Sales became worried their daughter, Indira, may have been exposed to the germs. Sales called the Center for Disease Control to inform them of the filthy situation.

A doctor has since given the toddler a clean bill of health.

For now, Sales and Mukherjee are holding onto the soiled diapers — they’re keeping them outside their home — in hopes that Amazon will investigate why and how they ended up with the used diapers in the first place.

“Whoever has done this, I am sure I am not the only one,” Sales said.
