“The results showed that the refrigerated eggs, regardless of whether they were washed or oiled, were still Grade A quality after 15 weeks, on average, and that the quality of eggs stored at room temperature declined rapidly. In fact, unwashed eggs stored at room temperature degraded from Grade AA to Grade B in just a week, and they also lost 15 percent of their weight over the 15 weeks. Under refrigeration, the unwashed eggs lost the same amount of weight as the washed eggs.
“Basically, the key is that egg quality stays high with refrigeration and degrades rapidly without it,” Jones says.”
I DO know that a goose egg found in shallow water, in summer, if broken in the canoe, makes you gag pretty bad.
