SALMONELLA serotype Enteritidis (SE) accounts for an increasing proportion of all Salmonella serotypes reported to CDC's National Salmonella Surveillance System. During 1976-1994, the proportion of reported Salmonella isolates that were SE increased from 5% to 26%. During 1985-1995, state and territorial health departments reported 582 SE outbreaks, which accounted for 24 058 cases of illness, 2290 hospitalizations, and 70 deaths. This report describes four SE outbreaks during 1994-1995 associated with consumption of raw shell eggs (i.e., unpasteurized eggs) and underscores that outbreaks of egg-associated SE infections remain a public health problem.
In August 1994, a total of 56 persons who ate at a Washington, D.C., hotel had onset of diarrhea; 20 persons were hospitalized. Salmonella group D was isolated from stools of the 29 patrons who submitted specimens; 27 of the 29 isolates further typed were identified as SE.An investigation by the
