Pomegranates are coated in a hard rind that needs to be removed before you can eat the seeds. Some people choose to wash the seeds after removing the rind, while others do not.  There is no right or wrong answer, as both methods are safe and will not affect the taste of the seeds. If you choose to wash the seeds, make sure to use cold water. Rinse them thoroughly and pat them dry before eating.  Washing the seeds will remove any traces of the rind and help to ensure that they are clean and free of bacteria. If you do not choose to wash the seeds, make sure to eat them soon after removing the rind.  The seeds are less likely to spoil if they are not exposed to water, but it is still important that you eat them within a reasonable amount of time.  Do not store them in the refrigerator. Pomegranates can be eaten raw, so the only real difference between washing them and not washing them is whether or not you are eating them right after peeling.
