An automated wax sprayer system for clean, washed or pasteurized shell eggs sprays a heated solution containing water and wax emulsion onto the eggs as they rotate and pass through a conveyer. The temperature of the wax coating on the surface of the egg shells is heated at or above a sanitizing temperature and sprayed on the surface of the egg shells where Salmonella contamination may be present. Salmonella contamination present on the surface of the egg shells is eliminated substantially immediately. Separate flow pumps provide a consistent flow of wax solution to individual nozzles for consistent application of the wax on the entire surface of the eggs.
