ABSTRACT:
Measurement of the acoustical resonances in eggs is shown to provide a rapid, noninvasive technique for establishing the presence of Salmonella bacteria. The technique is also sensitive to yolk puncture, shell cracks, and may be sensitive to other yolk properties and to egg freshness. Remote characterization, potentially useful for characterizing large numbers of eggs, has been demonstrated.
