Don't expect that you'll enjoy taking oregano oil, even if you love Greek food. It has a much more potent taste in oil form, so be prepared! Because oregano oil in its pure form is so strong, it should only be used when diluted; try a ratio of one part oregano oil to three parts carrier oil, such as olive oil.
To pasteurize meat, USDA and my chart give us minimum temperatures, like 165Â°F for poultry and 145Â°F for fish. But if you dig into the data by USDA scientists, you learn that this is a distillation of the facts designed to make things easy for the public. Pasteurization of meat is not just a matter of temperature.
Unlike other meats where you have different temperatures to achieve the doneness of your meat. Fish has always had one temperature for being done. The internal temperature for a done fish should be 145 degrees. At this temperature the fish should be opaque throughout and flake easily when tested with a fork.
