Hundreds of cases and testing errors: Doctors still haven't found the cause of the explosive diarrhea outbreak in the US.

A test on an iceberg lettuce sample for the parasite that caused a massive diarrhea outbreak that affected thousands of people in the United States has given an incorrect result, writes Air forceThe test showed the presence of a pathogenic agent where it was not actually present.

The U.S. Food and Drug Administration said on July 18 that a product sample from Taylor Farms, a supplier to Taco Bell, tested positive for Cyclospora.

To date, the source of the infection has still not been precisely determined.

There have been no deaths from cyclosporiasis, but at least 94 people have been hospitalized.

Taylor Farms announced Friday that it was voluntarily removing all iceberg lettuce sourced from central Mexico from the U.S. market.

The next day, the Food and Drug Administration clarified that the sample that tested positive was from a product that was not on the company's recall list.

The agency specifically clarified the difference: a product recall is a more stringent measure, requiring a company to notify customers and remove the product from circulation. A voluntary recall does not require such a notice, making it less extensive and less costly.

The sample itself was taken during a targeted inspection of imported products as part of an investigation into the sources of the disease outbreak.

"Cyclospora is difficult to detect, so our laboratory specialists re-examined the results and concluded that the signal we saw does not confirm the actual presence of the parasite and should be considered erroneous," the agency said in a statement released on July 19.

The first cases of infection were recorded on May 13.

Symptoms of infection may appear over time, sometimes taking up to two weeks. The main symptom is watery diarrhea that lasts several days and is accompanied by significant weight loss and loss of appetite.

According to the US Centers for Disease Control and Prevention, thousands of people have been infected with Cyclospora. The illness is linked to Taylor Farms iceberg lettuce, which was sold in Taco Bell restaurants in at least five states.

The agency is recommending against eating shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia.

The fast food chain itself said it had already removed all affected Taylor Farms products from its restaurants.
