A wave of foodborne illness outbreaks is sweeping across the United States in 2026, as the country recovers from a major cyclospora outbreak tied to tainted iceberg lettuce while salmonella surfaces in jalapeños, eggs, and even dog food. The volume of cases has already outpaced any year since 2020, raising questions about the resilience of the nation’s food safety systems.
The jalapeño-linked outbreak alone has caused at least 431 illnesses and 57 hospitalizations across more than two dozen states. Separately, a dual-pathogen outbreak involving E. coli and salmonella traced to alfalfa sprouts has sickened 55 people in 15 states.
The Numbers Behind the Surge
Publicly available data from the Food and Drug Administration’s investigations paints a stark picture. The agency has identified more than 12,800 illnesses tied to foodborne outbreaks in 2026, far surpassing recent totals. By comparison, only 895 cases related to foodborne outbreaks were recorded the previous year.
Drawing on case counts from the Centers for Disease Control and Prevention, the FDA’s figures confirm that the current cyclospora outbreak is the largest the agency has investigated in the United States since the 1990s. Even so, the official tally undercounts the true scope. The FDA counts only illnesses directly linked to a specific outbreak under investigation. Roughly 67 percent of the CDC’s 17,180 laboratory-confirmed cases have been tied to Taylor Farms’ iceberg lettuce, with the remainder connected to other outbreaks or isolated infections. The CDC is also aware of at least 11,844 additional cases that have not been lab-confirmed or require further analysis.
Why Cyclospora Is So Difficult to Contain
Historically, cyclospora infections were rare compared with common foodborne pathogens like salmonella and E. coli, typically causing a few hundred to a few thousand illnesses a year. Because the parasite was so uncommon, it is not part of standard gastrointestinal test panels, which can obscure the real size of an outbreak. Many people who develop diarrhea from the parasite may also never seek medical care.
The pathogen is notoriously hard to remove. It lodges in the crevices and folds of leafy greens, herbs, and berries, foods usually eaten raw. Food sanitizers are ineffective against it because the parasite forms a tough protective outer shell.
A Weakened Public Health System
Experts point to chronic underfunding of food safety systems, gaps in federal food policy, and recent cuts to public health infrastructure under President Donald Trump’s administration as key factors behind the surge.
“What is happening this summer just demonstrates to me the vulnerabilities in the system—and what happens when you stress the system,” says Barbara Kowalcyk, director of George Washington University’s Institute for Food Safety and Nutrition.
Since Trump’s second term began, the CDC has reduced its staff through layoffs and buyouts by roughly 3,000 employees, about a quarter of its workforce.
