R. Ridzon et al., 2 OUTBREAKS OF SALMONELLA-ENTERITIDIS ASSOCIATED WITH MONTE-CRISTO SANDWICHES, Journal of food protection, 60(12), 1997, pp. 1568-1570
We report on two outbreaks of Salmonella enteritidis which occurred in
1992; both were associated with Monte Cristo sandwiches. The first ou
tbreak, which occurred in Woods Hole, Massachusetts, was investigated
as a case-control study, and involved 74 persons. The second outbreak,
investigated as a cohort study, occurred in Brewster, Massachusetts,
and involved 32 persons. Monte Cristo sandwiches were strongly implica
ted in both outbreaks; the odds ratio in the case-control study was 43
, and the relative risk in the cohort study was 13. Food-preparation p
rocedures were reviewed and food handlers were educated about safe foo
d-preparation practices. Because of the short grilling time for Monte
Cristo sandwiches, (usually several minutes) the eggs used in the prep
aration may only be partially cooked. As a result, this food should be
viewed as high risk for S. enteritidis. Pasteurized eggs should be us
ed to prepare Monte Cristo sandwiches, especially in a commercial sett
ing.
