(RNN) - A prepackaged salad mix is the source of a stomach bug that sickened 78 people in Nebraska since June, according to the Nebraska Department of Health and Human Services. The same intestinal disease, cyclospora infection, affected more than 300 people in nine states, the Centers for Disease Control reported last week.
Officials have not established a connection yet between the national outbreak and the findings in Nebraska.
The Nebraska Department of Health and Human Services said the salad mix included romaine and iceberg lettuce, cabbage and carrots, according to a report by the Associated Press.
The parasite causes intense diarrhea, loss of appetite, weight loss, stomach cramps and pain, bloating, nausea and fatigue. Vomiting and body aches are also associated with infection, and it is common to feel extremely tired, according to the CDC.
People catch the rare disease by ingesting water or food that has been contaminated with feces passed by a person who is already infected.
The U.S. Food and Drug Association is working with local health departments to identify the source of the contamination and where the packaged salads were distributed.
Here is a list of states where outbreaks have been confirmed: Iowa, Nebraska, Texas, Wisconsin, Georgia, Connecticut, New Jersey, Minnesota and Ohio.
Illinois and Kansas earlier notified CDC of one case each that may have been acquired out of state.
