July 20 (UPI) -- Taylor Farms said late Sunday the Trump administration mistakenly informed it that a sample of its shredded iceberg lettuce tested positive for a parasite amid a multi-state outbreak that prompted the U.S.-based fresh-produce giant to initiate a recall of the salad staple distributed to 27 states.

The Food and Drug Administration reversed the finding Sunday, determining that the purported positive test for the microscopic Cyclospora parasite, which causes the intestinal illness cyclosporiasis, was a false positive.

"Today, FDA apologized to us," the company said in a statement.

"Today, we were informed that FDA made a mistake."

Taylor Farms had initiated the voluntary recall Friday after federal health investigators linked shredded iceberg lettuce sourced from central Mexico to a multi-state cyclosporiasis outbreak through a traceback investigation.
