Officials are not sure why the time between exposure and onset - which averaged 5.5 days - was so long in this outbreak. While it may have been a result of the type of Salmonella involved, says the study, it may also have depended on the amount of bacteria ingested or on a variation in the temperature of the food, which was prepared a week in advance and served cold.
