| Attack rate in attendees, no. ill/no. exposed or unexposed (%) |
||||
|---|---|---|---|---|
| Food itemsa | Exposed | Unexposed | RR (95% CI) | |
| Wedding cakeb | 50/53 (94.3) | 4/26 (15.4) | 6.1 (2.5 to 15.1) | |
| Fresh fruitc | 36/43 (83.7) | 18/36 (50.0) | 1.7 (1.2 to 2.4) | |

aMesclun lettuce was served as a garnish on several hors d’oeuvres trays, and basil was served fresh in one food item. Neither was significantly associated with illness.
bFood item was statistically significant in multivariate analyses (relative risk, 5.9; 95% confidence interval [CI] 3.6 to 10.5).
cFresh fruit included strawberries, raspberries, blueberries, and blackberries. Persons served themselves from a bowl of fresh strawberries and a bowl of fresh raspberries, blueberries, and blackberries next to the cake. The raspberries in the bowl came from a different source than the raspberries in the cake filling and were not statistically significant in multivariate analyses.
