There were numerous cases throughout the United States of patients having bloody diarrhea all within a week of each other, many of which were hospitalized with severe cases. Although the people spanned from California to New York, they all had attended a high school graduation party. Epidemiologists determined the common food factor was cheese curds homemade by a farmer. The home where the cheese curds were made was searched, and the cheese curds and milk to produce them were taken to the local government lab. Among other microbes, Campylobacter jejuni was isolated from many of the cheese curds as well as the farmer's bulk tank milk. What should be done for those infected? What can be done to prevent this from happening again?

It is estimated that less than 4% of all cases of salmonellosis are reported.
