(4) Uncooked, unpasteurized shell eggs may not be used for the preparation of ready-to-eat foods or foods that are not further cooked or baked.

(a) in refrigerated units at a temperature not to exceed 45oF (7oC) ;
(b) under potable running water of a temperature of 70oF (22oC) or below, with sufficient water velocity to agitate and float off loose food particles into the overflow for a period of time that does not allow thawed portions of a raw animal food requiring cooking to be above 45oF (7oC) for more than four hours;
(c) in a microwave oven only when the food will be immediately transferred to conventional cooking facilities as part of a continuous cooking process or when the entire, uninterrupted cooking process takes place in the microwave oven; or
