Consumer Advice
Carbon dioxide is the gas that creates the fizz in carbonated drinks; it is used as a propellant and carbonation agent, as well as for modified-atmosphere packaging and dry-ice cooling. It is non-toxic and has no calories, and most of it is released as a burp after drinking. At authorised uses it is completely safe; the frostbite and asphyxiation risks associated with dry ice or high-pressure gas concern industrial handling only, not finished foods.
