Health and Human Services Secretary Robert F. Kennedy Jr. says a nationwide investigation into a cyclosporiasis outbreak linked to shredded iceberg lettuce has reached a critical point, with officials now working to prevent additional illnesses.
The outbreak has affected at least 1,600 people across five states, prompting recalls, investigations, and renewed questions about food safety monitoring.
Kennedy said Tuesday that federal health officials believe the situation is “under control” after investigators identified a likely source and worked with companies involved to remove affected products from the market. The announcement comes as health agencies continue examining remaining cases and looking for any additional sources connected to infections reported in other parts of the country.
Officials Identify Lettuce Supply Chain as Key Focus of Investigation
The outbreak investigation has centered on shredded iceberg lettuce served at some Taco Bell locations. Federal health officials identified the lettuce as being supplied by Taylor Farms and sourced from central Mexico, leading to a voluntary recall involving numerous lettuce products distributed across multiple states.
Taylor Farms said it would stop sourcing iceberg lettuce from central Mexico for the remainder of the growing season following the investigation. The company also worked with health officials as they examined whether contaminated products contributed to the spread of cyclosporiasis.
Cyclospora is a parasite that affects the intestinal system and can cause symptoms including diarrhea, stomach cramps, nausea, loss of appetite, and fatigue. While many people recover with treatment, infections can become more serious for some individuals, especially if symptoms continue for an extended period.
Kennedy said investigators used detailed epidemiological work to trace the outbreak and identify the likely source. He said federal agencies and companies involved took action after the connection was established, including removing potentially affected products from circulation.
The investigation has not ended completely. Health officials are continuing to review cases and examine whether other factors may have contributed to illnesses reported outside the main outbreak areas.
Recall Expands After Testing Questions Surface
The lettuce recall became a major focus after health officials examined samples connected to the outbreak. Taylor Farms voluntarily recalled dozens of lettuce products across 27 states as a precaution while investigators worked to determine the extent of possible contamination.
A sample of shredded iceberg lettuce supplied by Taylor Farms initially tested positive for Cyclospora, raising concerns about whether additional products could be involved. However, federal officials later reviewed the results and determined the test result was a false positive.
Taylor Farms responded by saying the company was informed that the testing mistake had occurred. The company maintained that it continued cooperating with investigators while emphasizing its commitment to food safety procedures.
The testing confusion added another layer to a public health situation already drawing attention from consumers, restaurants, and lawmakers. Foodborne illness investigations often require multiple rounds of testing because officials must carefully confirm links before identifying a specific product as the source.
Even with the false positive result, officials continued investigating the original outbreak connection involving recalled lettuce products. The focus remains on understanding how contamination occurred and preventing similar incidents in the future.
Lawmakers Question Food Safety Oversight Changes
The outbreak has also sparked political debate over how the federal government tracks foodborne illnesses. Some lawmakers have raised concerns about recent changes to public health surveillance programs and whether those changes could affect the nation’s ability to detect outbreaks quickly.
Sen. Jon Ossoff of Georgia criticized Kennedy and the administration’s approach to food safety programs. He questioned why tracking for Cyclospora through the CDC’s Foodborne Diseases Active Surveillance Network, known as FoodNet, was no longer mandatory.
The CDC changed reporting requirements in 2025, making reporting optional for most pathogens except Salmonella and Shiga toxin-producing E. coli. Health officials have said doctors must still report cases through state health departments, which provide information for national disease tracking systems.
Ossoff argued that reducing certain surveillance requirements could make it harder to identify patterns in foodborne illnesses. He called on officials to explain whether Cyclospora tracking through FoodNet had been restored.
Kennedy rejected claims that federal surveillance efforts had been weakened. He said criticism of the government response was inaccurate and argued that officials were still conducting investigations, monitoring cases, and using scientific methods to trace infections.
According to Kennedy, changes to FoodNet involved removing what he described as unnecessary duplication rather than eliminating surveillance. He said other systems continue to provide information needed for outbreak investigations.
Health Officials Urge Caution as Investigation Continues
Although Kennedy says the outbreak is under control, health officials continue urging people to remain cautious. Food safety experts recommend paying attention to symptoms and seeking medical advice if illness develops after eating potentially contaminated food.
Cyclospora infections are typically linked to contaminated food or water. The parasite can spread when people consume items exposed to contaminated sources, making proper handling, washing, and preparation important steps in reducing risk.
Consumers should follow recall announcements and avoid eating products identified as potentially affected. Restaurants and food suppliers also play a major role by maintaining strict safety practices and responding quickly when concerns emerge.
The current outbreak highlights the challenges involved in tracking foodborne illnesses across a large country. Investigators often need to connect cases across different states, identify common exposures, test products, and confirm results before taking action.
For families, the situation serves as a reminder that food safety depends on cooperation between government agencies, companies, healthcare providers, and consumers. Even after officials identify a likely source, continued monitoring remains necessary to ensure new cases do not emerge.
Federal health agencies say they will continue reviewing reported infections and examining any additional information that could help explain the outbreak. While officials believe the immediate threat has been reduced, the investigation remains an ongoing effort to protect public health and strengthen food safety responses.
