Liquid nitrogen is extremely cold, with a boiling point of -196°C (-321°F). Contact with skin or other tissues can cause severe frostbite or cryogenic burns. Improper handling can result in accidents.

If not fully evaporated before consumption, liquid nitrogen can cause severe internal damage, including burns to the mouth, oesophagus, and stomach.

The rapid evaporation of liquid nitrogen can displace oxygen in the air, creating a risk of asphyxiation, particularly in enclosed spaces.

While liquid nitrogen can create interesting textures, it can also make food overly hard and brittle if not used correctly. Extremely cold temperatures can also alter the flavour profile of foods, sometimes in undesirable ways.

Some regions have strict regulations regarding the use of liquid nitrogen in food due to the associated risks. The potential for accidents and injuries can increase liability for chefs and establishments using liquid nitrogen, possibly leading to legal complications.
