Tarrant County Public Health issued a warning Monday about an outbreak of Cyclosporiasis, a foodborne illness caused by a microscopic parasite that leads to severe intestinal problems.
Tarrant County said there has been a spike in cases during July.
Prior to this month, there were just eight cases reported in the State of Texas, and Tarrant County had seen just one.
But there are now 69 Cyclosporiasis cases in Texas, nine of them in Tarrant County.
So far, health officials have not found the source of the outbreak. They are asking health care providers to test patients who have intestinal issues lasting more than a few days.
Doctors say symptoms of Cyclosporiasis usually begin two to 14 days after ingesting contaminated food or water. Diarrhea can last weeks or even months. Victims can also suffer fatigue, weight loss, abdominal cramps, bloating, increased gas, nausea, vomiting, and low-grade fever.
Tarrant County Public Health says past outbreaks in the U.S. have been linked to imported fresh produce, including fresh cilantro, pre-packaged salad mix, raspberries, basil, snow peas, and mesclun lettuce.
