The government that cut the systems designed to catch foodborne parasites is now scrambling to find the source of an outbreak those systems would have identified weeks ago.

"Cyclospora is a very hardy organism, and so it has the ability to adhere to the surfaces very, very well with our fresh produce and fruit."

— Dr. Nuwan Gunawardhana, infectious disease specialist at Columbia University

The Centers for Disease Control and Prevention is tracking 1,645 confirmed cases of cyclosporiasis across 34 states. There are more than 5,100 additional cases under investigation. One hundred forty-one people have been hospitalized. The parasite responsible, Cyclospora cayetanensis, causes explosive diarrhea, stomach cramps, nausea, and fatigue that can last for weeks. No deaths have been reported, but the CDC itself acknowledges the numbers are almost certainly much lower than the true tally.

The parasite is thought to be spreading through lettuce or salad greens. No specific grower, supplier, or product has been identified. As of mid-July, the investigation is still ongoing.

What makes this outbreak notable is not just its scale, but the fact that it is unfolding inside a federal government that deliberately dismantled the surveillance infrastructure built to catch it early.

Last summer, the Trump administration cut the CDC's Foodborne Diseases Active Surveillance Network, known as FoodNet, from tracking eight pathogens down to two. Cyclospora was among the six pathogens removed from mandatory reporting and downgraded to optional status. The program, which began in 1995, routinely communicated with more than 700 clinical laboratories across ten states and covered approximately 16 percent of the U.S. population. It was designed to identify emerging clusters before they became outbreaks.

The CDC's own website explains the reduction with bureaucratic language that masks the operational reality: "Narrowing FoodNet's reporting requirements is, in part, because the surveillance landscape has changed since the collaboration began in 1995." What the website does not say is that the change was made under Health and Human Services Secretary Robert F. Kennedy Jr., who has systematically reduced the agency's workforce by one quarter and redirected its priorities away from surveillance and toward his personal health agendas.

Translation: the government removed the early warning system, then expressed surprise when the alarm went silent.

The numbers tell a story that goes beyond one parasite. Michigan alone has reported between 501 and 900 confirmed cases, making it the hardest-hit state. New York follows with 161 to 300 cases. North Carolina, Illinois, Indiana, Kentucky, New Jersey, and Texas each reported between 31 and 80 cases. Connecticut, Florida, Georgia, Kansas, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia each have between 11 and 30 cases. A dozen more states round out the count with smaller clusters.

But Michigan is not one of the ten states where FoodNet operates. The FoodNet sites are Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, Oregon, Tennessee, and select counties in California and New York. Even if FoodNet had retained cyclospora in its mandatory reporting requirements, Michigan would have fallen outside its direct surveillance area. The outbreak would still have needed to grow large enough for passive state reporting to catch it.

Linda Yancey, an infectious disease specialist at Memorial Hermann Health System in Texas, told TIME Magazine that outbreaks like this may become more common as health officials work with reduced staff and limited funding. "Unfortunately with so many budget cuts, every federal agency is hurting for personnel and resources," she said. "We could be at a greater risk of foodborne infections because the FDA is so understaffed and underfunded right now."

The pattern should be familiar. Kennedy ordered a federal lab to stop researching Ebola last year. When the World Health Organization declared an Ebola outbreak in Africa a public health emergency this June, the U.S. was left scrambling. Measles, previously eliminated in the United States, has resurged under his tenure. When asked in an April hearing whether a child who died of measles might have survived if vaccinated, Kennedy replied, "It's possible. Certainly."

The practical reality for Americans this summer is simple and unsettling: the produce aisle is a gamble.

CNN spoke with several infectious disease experts about the outbreak. Dr. Dan Barouch, director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center, said the illness can last weeks if left untreated and may lead to dehydration, with children, elderly individuals, and immunosuppressed people at highest risk. Bagged salad mixes and kits have been specifically linked to previous cyclospora outbreaks in the United States and Canada.

Taco Bell announced it was removing some ingredients from its menu at select locations as a precaution.

The CDC's standing guidance is to wash produce under clean running water, scrub firm produce with a brush, and avoid soaps, bleach, or chlorine tablets. Dr. Gunawardhana noted that cyclospora is highly resistant to chlorine, making the common instinct to sanitize produce with household chemicals not just ineffective but potentially harmful. Cooking food to at least 158 degrees Fahrenheit kills the organism, which is why experts recommend prioritizing cooked vegetables over raw ones while the outbreak continues.

Don Stoeckel, an environmental microbiologist at Cornell University's Produce Safety Alliance, put it bluntly: washing and peeling reduce risk but cannot guarantee complete removal, and "even small amounts of pathogen, if consumed, can cause illness."

The irony is structural. The same administration that slashed foodborne disease surveillance also presided over rising grocery prices. The Bureau of Labor Statistics reported in July that four of six major grocery store food groups increased in price in June. Americans who want to avoid fresh produce to minimize their risk will need to buy meat, poultry, dairy, or eggs instead, which cost more. The people who cannot afford the safe option are the most likely to pay for it.

Kennedy's defense of the CDC cuts is ideological. "We're ending the era of federal policies that fueled the chronic disease epidemic and replacing them with policies that put the health of Americans first," he said in a public statement.

What this means in practice is that a disease caused by a parasite on your salad, which the CDC tracked for nearly three decades, is now optional to report. The agency's own website acknowledges that "the true number of people sick with cyclosporiasis was likely higher than the number reported" because some people recover without medical care and are never tested.

Dr. Gwen Biggerstaff, CDC deputy director of the Division of Foodborne, Waterborne, and Environmental Diseases, offered the most measured guidance available: "Follow our standing food safety practices and guidelines, and stay aware of the food safety alerts and investigation updates, so that they know what foods are safe and they know how to keep their families safe and protected."

It is the public health equivalent of telling passengers to hold on while the plane flies blind.

The cyclospora outbreak will eventually be traced to its source, or it will not. The 5,100 cases under investigation will either be confirmed or dismissed. The hospitalizations will resolve. But the structural damage is permanent until reversed: a surveillance network that caught foodborne threats for thirty years was reduced to two pathogens, and the staff who operated it were told their work was no longer a priority.

The question is not whether the next outbreak will be caught early. The question is why anyone believes it will be.
