MONTGOMERY– The Alabama Department of Public Health has reported 28 cyclosporiasis cases across Alabama. The cases are part of an ongoing national outbreak of the gastrointestinal illness.
Cyclosporiasis comes from the parasite Cyclospora cayetanensis. Health officials most commonly report the illness between May and August.
Cases acquired within the United States often involve contaminated fresh produce. Possible sources include lettuce, basil, cilantro, snow peas, berries, and melons.
Most Alabama Cases Reported in Northern District
As of July 20, ADPH had identified 22 cases in its Northern District. Those cases represent nearly 79% of Alabama’s reported total.
The Southwestern District has reported two cases. Mobile, Northeastern, Southeastern, and West Central districts have each reported one case.
Two people have required hospitalization. However, ADPH has reported no deaths connected to the illness.
Four cases involve international travel. Meanwhile, eight cases are associated with two separate foodborne outbreaks at Mexican-style restaurants. ADPH said those restaurants were not Taco Bell locations.
Federal Investigation Focuses on Iceberg Lettuce
Federal investigators have identified a link involving certain lots of shredded iceberg lettuce. The lettuce was served at Taco Bell restaurants in five states.
Those restaurants are located in Indiana, Kentucky, Michigan, Ohio and West Virginia. Currently, none of Alabama’s cases have direct links to those locations.
The Centers for Disease Control and Prevention and U.S. Food and Drug Administration continue investigating the outbreak.
FDA scientists also reviewed sample results from Taylor Farms de Mexico. The agency determined that a previously reported positive Cyclospora result was a false positive.
As of July 19, laboratory testing had produced no confirmed positive product samples. However, federal and state officials continue collecting and testing samples.
ADPH said Taylor Farms de Mexico and Taylor Fresh Foods are voluntarily removing iceberg lettuce from central Mexico. The companies took the step in cooperation with the FDA and out of caution.
The removal includes products supplied to KFC, Pizza Hut, Subway, Trader Joe’s and Walmart. It also includes products supplied to Sysco, Cross Valley Farms and Peak Fresh Produce.
Additional businesses could be announced as the investigation continues. The FDA is updating its website as new investigation and recall information becomes available.
Cyclosporiasis Symptoms and Testing
The main symptoms of cyclosporiasis include watery diarrhea, fatigue, and loss of appetite. Other symptoms may include stomach cramps, bloating, nausea, and weight loss.
Symptoms usually begin about one week after infection. However, they can begin anywhere from two days to more than two weeks later.
Without treatment, symptoms may continue for several days or longer than one month. ADPH advises anyone experiencing symptoms to remain well-hydrated.
Those who develop symptoms should contact a healthcare provider. Patients should also request specific testing for Cyclospora because routine stool tests may not detect the parasite.
Health officials may contact patients while trying to identify contaminated food. ADPH asks patients to provide detailed information about foods eaten during the previous two weeks.
Food Safety Steps That May Reduce Risk
ADPH recommends washing hands thoroughly with soap and water. Handwashing is especially important after handling raw produce and before preparing or eating food.
Fresh fruits and vegetables should be washed under running water before eating, cutting or cooking. However, washing alone may not eliminate Cyclospora.
Cooking produce to at least 158 degrees can kill the parasite. Consumers should also avoid eating recalled lettuce from grocery stores or restaurants.
Anyone unsure about the source of iceberg lettuce should ask the grocery store or restaurant. Consumers can also monitor ADPH, CDC and FDA websites for current outbreak and recall information.
