Fresh eggs will keep in the refrigerator about five weeks. Avoid serving raw eggs or foods containing raw eggs. Keep eggs refrigerated at a temperature no higher than 40 F. Do not keep raw or cooked eggs out of the refrigerator longer than two hours. Do not wash eggs before storing or using them. Use mayonnaise within two months after opening jar.
Mayonnaise contains lemon juice or other acid flavoring agents and salt.
This combination acts to retard bacterial growth, thereby increasing the food's resistance to spoilage.
