"They are double-double concentrated," Clancy told ABC News. "They also have a very, very attractive packaging so that kids see them, they touch them to their mouth, the surface coating dissolves as its supposed to in the washing machine and then the insides are under a little pressure, especially if you're gripping them with your little toddler hands.
"It squirts into your mouth it's very concentrated detergent," she said. "You take a breath, some of it goes into your lungs, you start to cough, oxygen saturation goes down, you don't have quite enough oxygen to your brain, you get lethargic, then you don't breath, then you throw up. It's a mess."
Clancy believes it is difficult for people to believe that detergent can be dangerous because so many have used it for so long without problems.
"I think that people need to understand that these are different," she said. "It's certainly not a problem that's going away."
"My recommendation is people not buy them if they have children below the age of 5 in their home," Lewis-Younger said. "However, if they're going to buy them, they need to lock them in a secure location, high."
She emphasized that basically any household product could be harmful to children, and said they all need to be stored safely away and that they need to be attended to when they are in use.
Lewis-Younger said that whenever there's an exposure, parents should call the poison control centers. The nationwide number is 800-222-1222.
The American Cleaning Institute, which represents producers of household, industrial and institutional cleaning products, did not immediately respond to ABC News' request for comment. On the homepage of the organization's website, there is a link to an educational pledge people can take to keep the single-load liquid laundry packets out of the reach of children.
