Outbreak of diarrhea-causing parasite linked to 4 more states

WASHINGTON (AP) — Federal health officials on Friday expanded the scope of their investigation into an outbreak of a diarrhea-causing parasite to four additional states, broadening the size of the largest U.S. outbreak of cyclospora.

The Centers for Disease Control and Prevention said the outbreak first tied to shredded lettuce served at Taco Bell restaurants now includes Illinois, Kansas, Oklahoma, and Pennsylvania. Previously the agency’s investigation included five states: Indiana, Kentucky, Michigan, Ohio and West Virginia.

The CDC, Food and Drug Administration and state health officials have been tracing the supply of the lettuce and interviewing people across the nation about the foods they ate two weeks before getting sick.

The number of cases linked to the lettuce is now 1,947, including at least 98 people who had to be hospitalized. There have been no deaths, the agency reported on its website.

The total number of people sickened by the outbreak is likely higher than the official tally, given that not all cases are reported, the agency noted.

FDA officials earlier this week said they remain focused on lettuce from Taylor Farms as the source of the multistate outbreak. The company last week announced it was recalling iceberg lettuce grown in central Mexico.

Asked when it would be safe to eat lettuce again, Trump said Friday that his government is “going to put a major tariff on tax on Mexico because of the lettuce.”

On Thursday, the FDA announced it was investigating a separate outbreak of cyclospora reported in 72 people. Regulators had not yet identified the products linked to the illnesses.

Overall, cyclospora cases have set a U.S. record. Since May 1, CDC has received reports of more than 4,100 laboratory-confirmed cases and is investigating more than 7,400 other likely cases across 41 states. Federal health officials have said that other “brands, restaurants, retailers, or distribution channels” could be tied to the outbreak as the investigation continues.

Cyclospora is a microscopic parasite that infects food that has come into contact with human feces, most commonly when produce is irrigated or washed with contaminated water. When ingested, the parasite causes intestinal illness marked by “frequent and sometimes explosive bowel movements,” according to the CDC.

Mexican health officials announced Thursday that the parasite was not detected in the lettuce or water at the Taylor Farms plant in the Mexican state of Guanajuato.

The results were announced following a visit by Mexican health authorities to the Taylor Farms plant between July 18 and 20, during which 10 samples of iceberg lettuce were collected. Four water samples also were collected for analysis, authorities stated.
