Codfish are known as thermal conformers. This means that their body temperature equals the surrounding water temperature. The deep waters that are home to the wild codfish that Rosita harvests are at a temperature of approximately 2°C to -1°C, and colder. So by refrigerating your Rosita EVCLO you are actually mimicking the temperatures that a living wild codfish liver is exposed to!
Remember, Rosita EVCLO is a raw fresh wholefood. In the same way that many other raw fresh wholefoods (like raw butter for example) require refrigeration to maintain freshness, so does Rosita EVCLO.
