However, if the eggs have been cooked, sealed properly, and kept in the refrigerator, they can generally be stored without problem for 48 hours.

      What kind of propaganda or bull is this? What journal of medicine, Scientific American, or other reputable source is this based from?? Don't even go there if you're thinking 'common knowledge'. If this is so dangerous, why hasn't there been more articles about this, and why do some of the articles only originate from a certain country??
