Sounds like blanching is the way to go to make it super clean before you consume it. Just make sure it is okay with your doctor. When someone's wbc is really low, they are super careful. When mine was really low and they couldn't do treatment, I had to eat a lot of boxed mac and cheese, but for the most part, as long as I cleaned, boiled, scrubbed everything like crazy, I could eat with caution. So much fun, right?
