Cyclospora found at Mexican farm linked to lettuce outbreak, FDA says

WASHINGTON (AP) — The Food and Drug Administration said Friday that its inspectors detected cyclospora at the Mexican farm blamed for the largest foodborne illness outbreak of the parasite in U.S. history.

Despite the finding, the FDA said it's unclear how the parasite got into lettuce at Taylor Farms' facility. The agency has now closed its investigation into the outbreak, which led to nearly 13,000 cases of diarrhea and other illnesses across the U.S.

The announcement comes more than six weeks after the agency sent its investigators to the farm in Guanajuato, Mexico. The visit was the agency's first time there in more than seven years following a steep drop in international food safety inspections after the COVID-19 pandemic.

FDA inspectors said Friday they found cyclospora in two places: a wastewater tank and a drainage ditch used for lettuce cultivation. While it's unclear how the contamination took place, the FDA said the samples provide “strong epidemiological data” linking the outbreak to the Taylor Farms site.

In a separate statement, Taylor Farms attributed the contamination cited by FDA to an independent grower “who is no longer part of our supplier program.”

“Our facility remains closed in central Mexico as we work with our research team to implement enhanced safety protocols from the field to the facility,” the company said.

U.S. officials last month declared the outbreak had ended.

Cyclospora is a microscopic parasite that commonly causes watery diarrhea “with frequent and sometimes explosive bowel movements,” according to the CDC. The illness, called cyclosporiasis, is less common than foodborne illnesses caused by other germs, including salmonella and E. coli.

The parasite is spread through human feces, and it still isn’t clear how sewage could have contaminated enough food to sicken so many people.

Regulators from Mexico's food safety authority announced in August that their own investigation did not detect cyclospora in the lettuce or water at the facility. That conclusion came days after the FDA was forced to retract a faulty test result that had incorrectly identified cyclospora in a sample of lettuce from Taylor Farms collected at the border.

WASHINGTON (AP) — A federal court in Texas on Friday temporarily blocked the Trump administration from building a border wall and other infrastructure across the state's Big Bend region, in a victory for opponents who have pushed back against a key campaign promise by President Donald Trump.

Landowners, businesses and environmentalists in the region have united to oppose the planned projects, which are part of a $46 billion effort by the Trump administration to line the southern border with a mix of 30-foot-tall steel walls, vehicle barriers, roads and surveillance technology.

Judge Kathleen Cardone said in her ruling that the plaintiffs were “likely to succeed on the merits of at least one of the claims in suit, that there is a likelihood that they will suffer serious, irreparable harm without an injunction, and that the balance of the equities and the public interest weigh in their favor.”

U.S. Customs and Border Protection and the Department of Homeland Security did not immediately respond to a request for comment.

The judge’s ruling includes Big Bend National Park, where opposition to the wall prompted the administration to briefly pause construction.

Opponents of the border wall project have argued that the 500-mile-long Big Bend region of Texas is so remote and the landscape so rugged that it serves as its own deterrent to illegal immigration and that the administration violated the law when it issued a swath of waivers allowing it to bypass numerous regulations in order to speed up border wall infrastructure projects.

The lawsuit brought by an environmental organization, advocates for a historic church in Ruidosa and a river guide argued that the Department of Homeland Security was wrong to circumvent regulations meant to protect the environment, culture, and archaeology of regions like the Big Bend area.

Laiken Jordahl, with the Center of Biological Diversity that brought the suit, called Cardone’s ruling a “total victory.”

“The bulldozers are going to be sent packing until she rules on the merits,” Jordahl said. “This is such a historic day for Big Bend and for Texas and the Constitution.”

The court's decision comes just weeks after the administration erected the first border wall panels in the Big Bend sector in mid-September.

The border wall project throughout the Big Bend sector has sparked bipartisan opposition.

Much of the opposition has been geared around CBP’s plans for inside the Big Bend National Park, which is prized for its beautiful landscapes, limestone cliffs and crystal clear night sky views.

When bulldozers were spotted clearing land in the park in August, it sparked widespread opposition with both Republicans and Democrats calling for the administration to stop. CBP paused all activity there, but that pause expired earlier this week. The administration has said it’s reevaluating plans for the National Park but has not yet said what it will do there.

Advocates for the park on Friday said they were happy with the judge's ruling but called on the administration to fix the damage already done to Big Bend National Park and develop alternative plans.

“Big Bend is no place for border barriers. It’s time for the administration to come to the table with the border communities that know Big Bend best, repair the damage from this ill-conceived project, and find new solutions," Tiernan Sittenfeld, National Parks Conservation Association President and CEO, said in a statement.

The judge’s ruling extends to areas upriver and downriver from the national park, where CBP has planned a range of border infrastructure projects that would largely require building across privately owned land.

In those areas, the government has been working to obtain permission from local landowners to survey and build on their land, but in a recent court filing, it said it was prepared to refer some cases to the Justice Department in which it had been unable to secure permission from landowners.
