Taylor Farms will stop sourcing central Mexico lettuce four months a year after Cyclospora outbreak

The details

Taylor Farms founder and CEO Bruce Taylor said in an Oct. 8 letter that the company will suspend harvesting and processing lettuce in central Mexico for sale in the U.S. and Canada during the Cyclospora season the CDC defines as May 1 through Aug. 31. The pause is indefinite.

The decision follows a summer cyclosporiasis outbreak linked to Taco Bell and to lettuce recalled from Taylor Farms. As of the FDA’s final update on Oct. 2, it counted 12,883 laboratory-confirmed illnesses, 570 hospitalizations and two deaths across 21 states. Illnesses began June 22, and the CDC declared the outbreak over on Sept. 11. The FDA first reported contamination in a sample from Taylor Farms de Mexico, then said that result was inaccurate after retesting. On Oct. 2 the agency closed its investigation without determining how contamination happened, but said Cyclospora was present where the lettuce was grown and processed and that epidemiological and traceback data pointed to recalled shredded iceberg from the Mexican operation.

What traceback found. The FDA’s traceback converged on a single supplier, Taylor Farms de Mexico, which supplied shredded iceberg lettuce to Taco Bell locations where people got sick. Investigators identified several farms and a processing facility. Two environmental samples tested positive for Cyclospora: one from a tank of outgoing wastewater at the processing plant and one from a drainage ditch at a grower. A positive product sample reported July 18 was ruled a false positive a day later.

How far the product went. Recalled foodservice product was confirmed in 31 states, with possible further distribution to several more. Walmart’s Marketside iceberg salad and shredded lettuce, with best-if-used-by dates from July 18 to Aug. 3, were sold in 15 states. Taco Bell said it stopped using lettuce from Taylor Farms de Mexico on July 17, the day Taylor removed central Mexico iceberg from the U.S. market.

The pause covers May through August, which Taylor says mirrors central Mexico’s rainy season. “This is personal to me and my family,” Taylor wrote.

Beyond the seasonal pause, Taylor says it will:

• Expand year-round health monitoring in the region
• Increase irrigation water and crop testing
• Invest in research on detecting and preventing Cyclospora
• Join a public-private task force with the FDA, scientists and industry on prevention measures for growers

How the FDA described the evidence. In closing its investigation, the FDA said it lacked enough evidence to determine how the contamination occurred, but cited “the strong epidemiological data and traceback convergence supporting the link” to Taylor Farms de Mexico, according to Supply Chain Dive. Supply Chain Dive reported in July that the FDA had found the lettuce sample did not contain the parasite after retesting. Taylor’s task force will include the FDA, scientists, industry leaders and public health officials, with a mandate that includes prevention measures for fresh produce growers.

Timeline

The scale. About 4.4% of confirmed cases were hospitalized, by our calculation from the FDA’s figures, and laboratory-confirmed counts typically understate total illnesses because many people never get tested. For a food business, an outbreak at this scale brings recall costs, lost sales and legal exposure well beyond the cost of the product itself, which is why food-safety terms in produce contracts deserve the same attention as price.

Planning around a known seasonal gap

A planned gap is easier to manage than a surprise one, but only if contracts reflect it. For summer 2027, procurement teams buying iceberg lettuce, directly or through distributors, should agree the following before annual produce contracts are set: which growing regions will supply May through August, at what volume, with what quality specification, and how freight from more distant regions will be priced. If your menu or product depends on a specific cut or blend, check whether alternate regions can supply it at the same yield.

What procurement teams should do

• Map the exposure. Identify SKUs, menus and sites that draw on central Mexico lettuce between May and August, including product bought through distributors.
• Ask for the replacement plan in writing. Request the alternate growing regions, committed volumes and expected price effect for summer 2027 before annual produce contracts are set.
• Revisit food-safety terms. Specify testing frequency, traceability to field level, and recall cost allocation in supplier agreements, not only in quality manuals.
• Qualify a second source. For high-volume items, a pre-approved backup supplier from a different region reduces the cost of the next single-region failure.
• Plan summer pricing. Expect suppliers to price the seasonal shift into bids. Ask for transparency on freight and yield assumptions rather than accepting a flat increase.

Questions to ask your produce suppliers

1. Which growing regions supply our product in each month, and what is the backup region for May to August?
2. What irrigation water and environmental testing do your growers and processing plants run, and how often?
3. How quickly can you trace a lot to the farm and field, and when did you last test that?
4. What happens to price and allocation if a region is paused mid-contract?
5. Will you share results from the FDA task force’s prevention measures as they are adopted?

What to watch next

• Summer 2027 sourcing. Watch where Taylor Farms sources lettuce from May to August and what that does to price.
• FDA task force. Prevention measures for growers could become industry expectations for all suppliers.
• Competitors’ response. Other processors may adopt similar seasonal pauses, which would tighten supply further.

The bigger picture

The episode shows how a single-region failure travels: one supplier’s operation, one fast-food customer’s menu, thousands of illnesses and a recall. Seasonal sourcing rules like this one are becoming a standard supplier-risk response in fresh produce. Category managers should treat them as planned capacity changes and negotiate around them early, rather than discovering them when summer volumes fall short.
