On Thursday, the New York Times reported that the Centers for Disease Control and Prevention had linked the outbreak of cyclosporiasis, an infection notorious for inducing explosive diarrhea, to iceberg lettuce from Taylor Farms that was supplied to Taco Bell. 

Per the reporting, Taco Bell said it was voluntarily pulling the lettuce from select states where it received the contaminated produce: Indiana, Kentucky, Michigan, Ohio, and West Virginia. An announcement from the CDC warned the public not to eat food items with shredded lettuce from Taco Bell, but hasn’t identified Taylor Farms as the source.

But while Taco Bell may have served the tainted lettuce, it would be remiss to lay all of the blame on the fast food chain (although one aggrieved customer is already suing it after contracting the illness).

The contamination occurred at the farms or facilities where the food was processed, from a single supplier in Mexico, Food and Drug Administration officials said. The supplier, Taylor Farms, has been involved in previous outbreaks, including another outbreak of cyclosporiasis in a salad mix in 2013.

Taco Bell, to its credit, also immediately pulled its ingredients from some of its locations last week as soon as it learned about the situation, according to local reports.

And then there’s the broader political context that many experts are drawing attention to: how the Trump administration has slashed funding to the CDC and paralyzed the nation’s food safety bodies.

Last February, shortly after Trump took office, the US Department of Agriculture (USDA) dissolved its National Advisory Committee on Microbiological Criteria for Foods, which provided scientific guidance on food safety policy. Ryan Cooper at The Prospect notes that the committee was working on advice for foodborne illness outbreaks before being terminated. The FDA also shut down its National Advisory Committee on Meat and Poultry Inspection.

Not spared during the wave of cuts that wreaked the federal government, the USDA lost over 20,000 workers last year, with 913 of them coming from its Food Safety Inspection Service.

Last year, the CDC — which has lost some 3,000 employees under Trump — scaled back its food surveillance program called FoodNet that monitored eight common foodborne pathogens, changing it so that surveillance of the cyclospora parasite that causes cyclosporiasis was optional.

Dan Jernigan, a former director of CDC’s Center for Emerging and Zoonotic Infectious Diseases, told the Washington Post that the decision was made because funding for food safety had not been maintained over the past few years. That the US is now on track to have more cyclospora cases this year than any previous year in history is likely no coincidence.

Other incidents show how the administration has taken a recklessly laissez faire approach to public health. The US’s worst measles outbreak this century occurred after Trump had hollowed out the CDC — and after health secretary RFK had spent years heavily promoting anti-vaccine rhetoric. The CDC also reportedly fired its ship inspectors last year, a decision that came under scrutiny during a deadly hantavirus outbreak on a Dutch cruise ship. Some experts estimate that hundreds of thousands and possibly millions of children have died as the result of Trump dismantling USAID, which funded emergency food assistance programs and HIV response across the globe.

Jernigan left the agency last August in protest of Trump ousting its then director Susan Monarez and the policies of health secretary Robert F Kennedy Jr. But he said that the Trump cuts would have little impact on the ongoing outbreak, adding that FoodNet wasn’t designed for real-time outbreak detection or response.

As the WaPo reporting notes, federal and state health authorities have insisted that the cyclosporiasis investigation hasn’t been impeded because the parasite is still reportable to a separate national database. Still, Jernigan said that scaling back FoodNet wasn’t inconsequential.

“Routine outbreak investigators are the firefighters responding to a specific blaze. FoodNet is the citywide system that tracks how often fires occur and whether the overall risk is rising,” he told WaPo. “Removing cyclosporiasis from FoodNet does not take the firefighters away from the current outbreak, but it does remove part of the system that tells us how large the problem is and whether it is getting worse over time.”

Cyclosporiasis is a particularly tough illness to track.  Symptoms can take weeks to present, making it difficult for health officials to trace back where sufferers were infected. A recent Wired piece drew attention to how many people may be wrongly misdiagnosing themselves as news of the diarrhea dilemma spread across social media.

Linda Yancey, an infectious disease specialist at Memorial Hermann Health System in Texas, warned that large outbreaks like this could become more common.

“Unfortunately with so many budget cuts, every federal agency is hurting for personnel and resources,” she told Time Magazine earlier this month. “We could be at greater risk of foodborne infections because the FDA is so understaffed and underfunded right now.”

So far, Michigan, the epicenter of the outbreak, has alone tallied over 4,300 cases of infection, while nationwide there could be 7,000 cases, though the Centers for Disease Control and Prevention has only confirmed 1,600 of them.
