Taylor Farms has recalled several lettuce products after federal officials linked it to a widespread cyclosporiasis outbreak, though an investigation into the exact source of the parasitic illness is still ongoing.
The U.S. Food and Drug Administration, which initially announced that a sample of lettuce from Taylor Farms had tested positive for cyclospora, has since said the result was a false positive.
None of the samples tested for cyclospora in this outbreak have been confirmed positive as of July 19, the FDA said. The agency said it continues to work with Taylor Farms as it investigates the source of the outbreak and test samples.

Taylor Farms remains linked to the outbreak through the FDA investigation and "out of an abundance of caution" issued an expansive voluntary recall of iceberg lettuce products on July 17.
The FDA said the lettuce was sold in part through Taco Bell locations in five states.
Cases of cyclosporiasis have surged in more than 30 states in recent weeks. People who contract the illness usually have "explosive" diarrhea and other severe gastrointestinal issues. Here's a look at all the products pulled so far tied to the outbreak.

What is cyclosporiasis? Symptoms, treatment
Cyclosporiasis is caused by the microscopic parasite Cyclospora cayetanensis, according to the Centers for Disease Control and Prevention.
The illness is not usually life-threatening and can be treated with antibiotics, but symptoms may last longer for those who are immunocompromised, according to the agency.
Common symptoms of cyclosporiasis include diarrhea, cramping, bloating, nausea and fatigue.
While some people who are infected may not have symptoms, those who do may be sick for up to a month or more, per the CDC.
