Eggs sold loose in trays are not considered to be prepackaged (unless they are overwrapped).
"Many types of pathogens and spoilage bacteria are prevented from multiplying in properly refrigerated foods that are not out of date," the FDA site says.
That's why the USDA published a final rule requiring all shell eggs packed for consumers to be stored and transported at 45 degrees F.
