A cyclospora outbreak that has sickened thousands of Americans is exposing a structural flaw in the nation’s food supply: decades of consolidation have made it easier than ever for a single contamination event to travel from one field to dinner plates across dozens of states.
Federal investigators have traced the current outbreak to shredded iceberg lettuce distributed through Taylor Farms’ foodservice business, an ingredient that reached Taco Bell restaurants and other foodservice customers nationwide. Food safety experts say the case illustrates how centralized sourcing and distribution networks can amplify what once would have been a localized contamination problem.
How Consolidation Reshaped the Food Supply
Over the past several decades, U.S. agriculture and food distribution have steadily consolidated as companies pursue efficiency and national scale, according to the USDA. That push has concentrated fresh produce handling into fewer hands — and experts argue the trade-offs for food safety are now becoming visible.
“The general trends that have taken place in the food industry, the way in which food has been sourced and then distributed has played some role here,” said Dr. David Relman, a professor of microbiology and immunology at Stanford University.
Relman pointed to bagged lettuce as a concrete example. “Think of the difference between one head of lettuce and a bag of chopped lettuce that may have come from many, many heads,” he said. “These bags are now being produced in huge numbers and distributed in far-flung distribution networks.”
“It’s possible that as food sourcing and distribution becomes consolidated you get pooling and then redistribution of what might have been a very local contamination problem, so that it now becomes a widely distributed contamination problem,” Relman added.
Taylor Farms and the Reach of a Single Processor
Taylor Farms, the salad producer under scrutiny for the recent cyclospora outbreak, has expanded significantly through acquisitions over the past decade — including Earthbound Farm in 2019, Curation Foods in 2021 and most recently Equinox Growers in March. Each deal broadened the company’s footprint in fresh-cut produce, the very category at the center of the current investigation.
Marion Nestle, professor emerita of nutrition, food studies and public health at New York University, said the shrinking of the industry has amplified the consequences when contamination occurs. “Consolidation means that if something goes wrong, it goes wrong big time,” she said. Centralized processing can further expand the reach of an outbreak, she added.
The Distributor Layer: Sysco, US Foods and National Reach
Restaurant supply has become increasingly concentrated as well, with broadline distributors like Sysco, US Foods and Performance Food Group serving hundreds of thousands of restaurants and institutional kitchens nationwide.
Federal regulators blocked Sysco’s proposed $8.2 billion acquisition of US Foods in 2015 on antitrust grounds, but both companies have continued growing through smaller acquisitions of regional distributors and fresh produce processors. Sysco, the nation’s largest foodservice distributor, spent the past decade expanding its fresh produce business by acquiring regional distributors including Paragon Foods in Pennsylvania, The Coastal Companies in the mid-Atlantic and Greco and Sons, a specialty food distributor with 10 distribution centers across the country.
In 2016, US Foods acquired Freshway Foods, a fresh fruit and vegetable processor, repacker and distributor in the eastern half of the United States. Those deals expanded distributors’ reach in fresh-cut produce and value-added processing, allowing a larger share of restaurants to source ingredients through the same distribution network.
A Counterargument: Bigger Can Mean Safer
Not everyone agrees that consolidation is the enemy of food safety. Timothy Lytton, a health and safety regulation expert at Georgia State University, said larger produce growers and processors often operate with more sophisticated food safety systems than smaller farms because they have the financial resources to invest in testing, traceability, audits and quality control.
“It’s not entirely clear that larger operations have more food safety problems than smaller operations,” Lytton said. In California, he noted, studies at farmers markets have found fresh produce grown by small farmers contaminated with E. coli. He pointed to organic farming models that place animals near crops as a potential contamination risk.
Even so, Lytton acknowledged that when contamination does occur within large handler networks, the resulting recalls at the distribution level are much broader and harder to manage.
The International Foodservice Distribution Association, responding on behalf of major distributors including Sysco, defended the industry’s tracing capabilities. “The foodservice supply chain that feeds our communities is intricate and foodservice distributors are highly skilled in tracking and tracing the food they distribute,” an IFDA spokesperson said. “They maintain robust records, identifying the source, internal movement, and recipient of all products they handle, and they have a proven track record of providing FDA with critical traceback information within 24-48 hours to support foodborne illness outbreak investigations and swiftly remove products from commerce.”
What Happens Next
The cyclospora parasite’s long incubation period, the difficulty in tracking its path and what some experts have criticized as a bumpy federal response have all complicated the current investigation. As FDA continues tracing the contamination to its origin, the debate over whether the food supply’s structure itself is a risk factor is likely to intensify.
Relman stressed that while consolidation itself doesn’t create contamination, it does change the consequences when contamination occurs. “We often don’t appreciate a system like the food inspection system, or the public health system in large until it fails,” he said. “We can’t keep doing that.”
For regulators, the question now is whether the same efficiency gains that drove consolidation can also deliver faster traceback and recall capabilities — or whether the food supply’s growing concentration has outpaced the safety systems meant to contain it. With each new multistate outbreak, that gap becomes harder to ignore.
