A nationwide outbreak of cyclospora, linked to contaminated iceberg lettuce, has amplified concerns about the safety of imported food and highlighted a consistent decline in international inspections by the Food and Drug Administration (FDA). Since 2019, the year before the COVID-19 pandemic, inspections of foreign food facilities, including the Mexican farm associated with the current outbreak, have decreased by nearly 35%, according to agency records.
Even prior to the pandemic, the FDA frequently failed to meet congressionally mandated targets for international inspections. Staffing reductions, reorganizations, and other administrative changes during the Trump administration may have further contributed to a decrease in inspections in subsequent years, according to former senior FDA officials. Michael Rogers, who served for nearly 35 years in various FDA inspection roles, stated that the agency's resources are insufficient to meet its oversight responsibilities for both domestic and international firms.
The Trump administration explored alternative approaches to optimize resources, such as a pilot program for one-day inspections. However, officials like Rogers contend that these abbreviated inspections do not equate to traditional, in-depth inspections, which can extend for a week or more and are crucial for documenting significant issues.
FDA officials have consistently argued that inspections are only one component of ensuring food safety. Susan Mayne, former director of the FDA's food program and now affiliated with Yale University, noted that given the vast quantity of imported products, inspections alone cannot guarantee safety. She emphasized the agency's reliance on other measures, including border inspections, importer verifications, and product sampling.
The recent outbreak, however, has exposed potential vulnerabilities in these alternative strategies. In July, regulators rescinded a test result that they had claimed detected cyclospora in a lettuce sample from Taylor Farms at the border. Despite this error, FDA officials maintain confidence that the company's farm is the source of the parasite. Mexican food authorities, conversely, have reported no positive findings or other concerning indicators at the farm.
A spokesperson for the Department of Health and Human Services, which oversees the FDA, confirmed that the investigation is ongoing. The FDA is also evaluating the necessary number of foreign inspections annually to ensure oversight comparable to that of the domestic food supply.
FDA inspectors visited the Taylor Farms facility in Guanajuato, Mexico, in mid-August, approximately one month after the recall was initiated on July 17. This marked their first inspection of the site since 2019, which was a peak year for foreign food inspections before pandemic-related field staff reductions.
Inspections for food, drugs, medical devices, and other products have not yet recovered to pre-pandemic levels. Foreign food inspections experienced a further decline in fiscal year 2025, dropping 17% from the previous year to 1,140. Although inspectors were not among the 3,500 positions targeted for elimination by the Trump administration, the agency reduced its staff responsible for travel logistics, requiring inspectors to manage their own flight and lodging arrangements.
Food safety experts have expressed concern that it took four weeks to deploy inspectors to the site in Mexico, particularly given the outbreak's scale and the number of affected individuals. Frank Yiannas, former top food safety official at the FDA, stated that rapid response is critical when outbreaks occur in fresh produce, given the dynamic nature of these environments.
The Taylor Farms recall encompassed thousands of packaged salad products containing iceberg lettuce and other vegetables, distributed to major U.S. restaurant chains, including those owned by Yum Brands. This fiscal year, companies have announced over 480 food recalls, surpassing the total for four of the previous five fiscal years.
Previous efforts to reform the U.S. food safety system include the Food Safety Modernization Act of 2011, enacted following a series of fatal outbreaks. This legislation mandated enhanced testing, training, and hygiene monitoring at farms, and established ambitious goals for FDA foreign inspections, which the agency has consistently failed to meet. The law requires the FDA to inspect over 19,000 international food sites annually, but the agency reached a high of only 1,700 in 2019, according to the Government Accountability Office (GAO).
Former FDA regulators suggest the 19,000 inspection target is unrealistic and has been inadequately funded by Congress. The GAO has noted that the FDA has not yet established an appropriate annual target.
Recruitment and retention of inspectors pose significant challenges to increasing inspection numbers. The FDA's food inspection workforce, numbering over 420 staff, has faced chronic understaffing, with 10% to 15% of positions unfilled. The demanding nature of international inspections, which can require inspectors to travel more than 50% of their working time, contributes to high turnover rates.
Rogers indicated that improving incentives to retain inspectors is crucial for the agency to increase its inspection capacity and effectiveness. Experts are exploring new methodologies, such as machine learning and remote monitoring of supplier practices, to supplement traditional inspections. Yiannas emphasized the need to re-evaluate foreign producer oversight using updated approaches beyond those used for the past three decades.
Further complicating safety measures, a requirement from the 2011 food safety law for manufacturers to place bar codes on produce batches for rapid traceability has been delayed. The FDA postponed the implementation of this rule, which was set to take effect in January, following industry pushback. Brian Ronholm, a former Department of Agriculture official now with Consumer Reports, commented that while the issues are complex, extended preparation periods should allow for successful implementation.
