In March 2012 the Mecklenburg County Health Department investigated an outbreak of Salmonella serotype Enteritidis among customers of the Toast of Dilworth Cafe in Charlotte. Health department investigators reported at least 29 ill persons with 15 persons diagnosed with salmonellosis. The suspected food that caused the outbreak was hollandaise sauce prepared with unpasteurized eggs. Once the sauce was mixed, it was held at room temperature. Allowing pooled eggs to sit at room temperature is a critical food safety violation.
