The Haryana government has officially prohibited flushing/mixing of liquid nitrogen with any drink or food article. The ban has been issued under the provisions of the Food Safety and Standards Act, 2006 (Central Act 34 of 2006). As per officials, the state food department will now conduct surprise checks in restaurants and bars, especially those in Gurgaon, to check whether the ban was being flouted. According to expert medical opinion, any drink or food article whose preparation involves flushing/mixing of liquid nitrogen is harmful for humans. Liquid nitrogen is a colourless liquid having a boiling point of -195.79 °C and is used to instantly freeze food and drinks. It is used in bars to quickly chill glasses, freeze ingredients, and provide a smoky effect to drinks and in molecular gastronomy. It releases a large volume of gas as it evaporates, which can burst the stomach if consumed in a sufficiently large quantity. It is also used to cool computers and in cryogenic medical procedures like removing warts and cancerous tissues by freezing them.
