Doctors say super-cold frozen treats can be dangerous to digestive system

NEW YORK, NY - Liquid nitrogen frozen treats are the latest dessert craze sweetening people's taste buds, but doctors say while they're fun, they could be dangerous to the digestive system.

At Cryo Cream, part of Broadway Bites in New York City’s Herald Square, Executive Chef Matthew Marotto sells liquid nitrogen-infused popcorn and ice cream.

He’s named the treats Dragon Breath.

“The popcorn, I've been doing it since 2007, so that's 11 years now.  And I'm completely fine,” Marotto said in response to the idea his culinary creations could be dangerous.

Health officials in Suffolk County, New York are advising against eating foods infused with liquid nitrogen, saying it could cause burns to the mouth and esophagus.

Another county in New York has banned restaurants from serving nitrogen-infused foods. 

Dr. Robert Glatter is an emergency physician at Lenox Hill Hospital. He isn't aware of any cases where someone was injured by eating these super cold foods, but he’s also not interested in taste-testing.

"In addition, we're talking about burns to the fingers, the hands, because if you handle it, this chemical is minus 300 degrees Celsius and that causes an instant burn and that can really cause a devastating injury long term," Dr. Glatter told Fox News.

Those who are drawn to this fascinating treat aren't concerned about the potential risks. Many are more interested in perfecting how to breathe like a dragon.
