DALLAS There are new clues about the source of a food-borne illness that just keeps spreading.
In North Texas, health officials have not yet narrowed down the source of the cyclospora outbreak, even though officials in Iowa and Nebraska point to bagged salad being the culprit.
The cyclospora parasite is typically found in produce.
More than 370 people are sick in fifteen states, including 122 in Texas. Most of those cases are in Collin, Tarrant, Denton and Dallas counties.
The salad mix of iceberg and romaine lettuce, cabbage and carrots is sold under multiple brands, but those brands are not yet being identified by health officials.
Health officials have not determined the source of the Texas outbreak, but they are following leads, looking at each case to find a common link.
A North Texas woman who asked not to be identified said one of her relatives tested positive for the stomach bug. That person has been sick for weeks with diarrhea, fatigue and stomach cramps.
"I see the anguish and the pain that she's had to go through with all the different symptoms and doctor's appointments and doctor's visits and having to drop off things and wait for results," she said. "I would really just like to see that there's an answer."
The mission now: Identify where the product was distributed, and where it became contaminated.
Prepackaged salad is triple-washed, so experts believe it could have been contaminated in a wash or from a problem with field irrigation water.
Dallas County health officials told News 8 that even though the source of the Texas cyclospora outbreak has not been determined, the revelation in Iowa and Nebraska could help their investigation.
If you or someone you know has suffered longer than a week with severe stomach cramps, nausea, acute diarrhea and vomiting, see a health professional and ask to be tested specifically for cyclospora. Don't wait to get help.
