FDA: Avoid Frozen Desserts and Drinks Made with Liquid Nitrogen
The U.S. Food and Drug Administration (FDA) is telling consumers and retailers to avoid eating, selling, or handling food products that are prepared by adding liquid nitrogen at the point of sale, immediately before consumption. The products FDA has named include Dragon’s Breath, Heaven’s Breath, and nitro puff, but there are others as well.
According to Wikipedia, these products are frozen desserts made from cereal dipped in liquid nitrogen. When placed inside the mouth, it creates vapors that emit from the mouth and nose.
