1997 Wisconsin Eggs

Reported Salmonella Enteritidis infections had doubled during 1997 in Wisconsin. In particular phage type 13a was identified. However, during November, an outbreak of Salmonella Enteritidis, phage type 8, occurred among restaurant patrons who ate Eggs Benedict with hollandaise sauce. A case-control study revealed that eating raw or undercooked eggs, eating any eggs, or dining at the restaurant were associated with developing Salmonella Enteritidis infection. For three of eight outbreaks, the probable vehicle were foods containing eggs.
