Days after the Food and Drug Administration advised consumers to avoid eating treats prepared using liquid nitrogen, a Valley business that sells them is closed down.
The frosty treats are called "dragon's breath" because as you eat them, they release a thick fog.
But how dangerous are they?
The liquid nitrogen is used to freeze cereal into little balls when you bite into them, creating a fog you can blow out of your nose and mouth.
But the FDA says they've been seeing dangerous injuries to the skin and internal organs caused by cold treats prepared with liquid nitrogen.
"Liquid nitrogen is a minus 320 Fahrenheit, roughly, so it's very very cold and it can cause a burn injury because it really frostbites. It can cause frostbite to the cheek, the tongue, anything in the oral cavity," said Dr. Dany Quan, an emergency physician and toxicologist with the Maricopa Integrated Health System.
It's so cold it can burn.
That's why experts advise you to avoid this kind of sweetness.
In the past couple of weeks, a chain of two local dragon breath stores have shut their doors.
"Patients that have lung problems, lung issues like asthma may be a little more susceptible to the chemical release from the dragon's breath," Quan said.
Such was the case for a Florida boy whose mom posted on Facebook they had to rush him to the hospital after he ate dragon's breath and stopped breathing.
"I hate to say that you shouldn't eat anything like that but you just have to exercise caution with eating these really cold foods," said Quan.
So we can verify dragons breath treats can be dangerous if you don't use caution.
"Just be aware of what it could potentially do to you," Quan said.
