Thursday’s federal refresh did not put a new bag of lettuce in a cooler. It added names to a list that has been growing since June. The cyclospora outbreak linked to processed iceberg from Taylor Farms de Mexico now stands at 11,458 laboratory-confirmed illnesses across 20 states — 495 hospitalizations, two deaths, last reported onset Aug. 15. Three states joined the case map this week: Georgia, Tennessee, and Texas. That is the largest U.S. Cyclospora cluster on record, and the investigation is still marked open.

What Thursday’s update actually changed

Live notices, not press-release spin: FDA’s multistate iceberg-lettuce investigation page and CDC’s Cyclospora outbreak alert (updated Aug. 27). Both stamp the same Thursday numbers. The prior refresh, Aug. 20, had 10,930 illnesses in 17 states. This week’s add is 528 confirmed cases and three states. Associated Press put that expansion on the wire Friday morning; a full copy is on WWSB’s AP pickup.

FDA’s own sentence on the product is the one that matters for anyone still staring at a crisper drawer: the agency “remains confident that all recalled iceberg lettuce related to this specific Cyclospora outbreak is off the market.” Best-by dates on the retail Marketside packs ran to Aug. 3. Onsite inspections and sampling at growers and the processing plant in Mexico, coordinated with Mexican officials, are still running. That is traceback and farm work, not a second recall of a new lot.

The two deaths were first detailed in FDA’s Aug. 5 note: both in Michigan, both in people with significant underlying conditions that cyclosporiasis and dehydration could have made worse, both with illness onset before Taylor Farms’ voluntary recall on July 17. Thursday’s table still reads two deaths. Do not treat that as a new fatality this week.

Why the cyclospora outbreak count still climbs

Cyclospora is a terrible reporter’s clock. CDC’s line, repeated on the FDA page since early August: it can take as long as six weeks to decide whether a sick person belongs in this outbreak. The parasite is not on a standard stool panel. A clinician has to think to order it. Patients wait days or weeks before they go in. Labs in the hardest-hit states ran short of kits in July. The interview that assigns a meal to an outbreak happens after the laboratory result, not before it.

FDA is explicit that most illnesses in this file began before the July 17 recall. Last onset in Thursday’s table is Aug. 15 — a handful of August dates, not a Labor Day wave of new exposures. If you ate a taco on July 4 and you are still logging watery stools in late August, you can still land in next week’s add. If you bought a fresh head of iceberg this week from a different supplier, you are not in this recall. You are also not automatically in the clear: CDC is tracking other cyclosporiasis that is not this lettuce.

Same consumer habit as other pulls we have walked — match the identifier, then stop guessing from a headline. Lot and date on a freezer box in the Outshine fruit bars recall; VIN in the Toyota Camry/Tacoma recall. Here the identifier is a best-by window and a brand line on a bag that should already be gone.

Taco Bell, Marketside, and the foodservice bags

FDA’s traceback in mid-July converged on a single supplier of shredded iceberg used at Taco Bell locations where sick people had eaten — first in Indiana, Kentucky, Michigan, Ohio, and West Virginia, then far beyond that five-state start. Taco Bell told regulators it stopped using lettuce from Taylor Farms de Mexico as of July 17. A meal after that date at that chain is a different exposure question. A meal in late June or the first half of July is in this file if the stool test later says Cyclospora.

Retail consumers saw the recall as Marketside at select Walmart stores. Company announcement, posted by FDA:

The bigger volume was foodservice: chopped, shredded, and blend packs under house codes CV, JB, MARK, PK, SUB, SY, TF and others, packed in 4/5-pound bags, distributed roughly June 29 through July 16. That is restaurants, cafeterias, sandwich shops — not only a taco chain. The full SKU table, lot windows, and discard instructions sit in Taylor Fresh Foods’ FDA-hosted recall announcement. Consumer line on that notice: 855-455-0098, weekdays 8 a.m.–5 p.m. Pacific. Refunds were at the place of purchase. Those dates have passed; the phone is still the company’s listed contact if a foodservice invoice is sitting in a manager’s email.

One lab footnote that still circulates as a rumor: on July 18 FDA reported a border sample as positive; on July 19 the agency walked it back as a false positive that “does not represent true amplification.” FDA said that walk-back does not change the epidemiology or the recall. As of that July 19 note, there were no confirmed positive product tests. This outbreak was built on interviews and traceback, not a smoking-gun swab in a bag.

Twenty case states vs the bigger distribution map

Confirmed illnesses (CDC/FDA, Aug. 27): Arkansas, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Massachusetts, Maine, Michigan, Missouri, Nebraska, New Hampshire, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, West Virginia.

Confirmed product distribution is wider than the case map. FDA lists recalled iceberg as confirmed in Alabama, Arkansas, Connecticut, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Missouri, Mississippi, North Carolina, Nebraska, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Wisconsin, and West Virginia — and says it may have gone farther, including D.C., Delaware, North Dakota, Puerto Rico, Rhode Island, South Dakota, Vermont, and Washington. A state with no case in Thursday’s table can still have received the bags. A state on the case list can have illnesses that ate the lettuce while traveling. Do not read “not on the 20” as “we never got the product.”

Taylor Farms also told FDA the same recall hit consumers in Mexico. This is not a U.S.-only shipping error.

What Cyclospora does in a gut

Cyclospora cayetanensis is a microscopic parasite. People get it by swallowing food or water contaminated with feces that contain the organism. It is not a typical person-to-person kitchen bug. CDC’s season is May through August. Heat-loving, produce-linked, easy to miss.

Common picture, from CDC’s outbreak page and the July 14 clinician alert CDCHAN-00531:

• Watery diarrhea, often frequent — CDC’s consumer phrasing is “explosive”
• Loss of appetite and weight loss
• Cramps, bloating, gas, nausea
• Fatigue that outlasts the bathroom trips
• Sometimes low-grade fever, headache, body aches, vomiting

Onset is usually about a week after the meal, with a range from two days to two weeks or more. Untreated, it can run a few days to a month or longer, and it can seem to stop and then come back. That relapse is the tell that sends people back to urgent care thinking they “caught it twice.” Complications in the HAN: malabsorption, cholecystitis, reactive arthritis. Immunocompromised patients get a longer, meaner course. Some infected people have no symptoms at all, which is why a household can split between “fine” and “still in the bathroom.”

Hydration is the first-aid step. Bloody stool, high fever, dizziness that does not clear, or no urine is an emergency-department visit, not a wait-for-Monday plan. Tell triage you may have cyclosporiasis after iceberg lettuce or a Taco Bell meal in June–July. They will not guess that from “GI bug.”

Ask for the test; washing is not a kill step

Routine ova-and-parasite exams miss Cyclospora. CDC tells clinicians to specifically request Cyclospora testing — modified acid-fast stain or a molecular/PCR gastrointestinal panel that includes it. If a doctor orders “stool studies” and the lab runs the everyday bacterial panel, you can get a false all-clear while the parasite is still there. Bring the CDC outbreak page on your phone. It is faster than arguing from memory.

Washing produce under running water is still the right kitchen habit. It is not a guarantee. CDC’s prevention page is blunt: washing alone cannot guarantee removal; cooking to at least 158°F (70°C) kills the parasite. Chemical sanitizers that work on a cutting board do not reliably kill Cyclospora on lettuce. Pre-washed bags are not a magic shield — the HAN told the public to wash even produce labeled pre-washed, which is advice for risk reduction, not a claim that a salad spinner would have stopped this outbreak.

If you are already in a clinic this month for something else — a 2026–2027 flu shot, an RSV vaccine visit — mention lingering watery diarrhea. Fall respiratory season is a useful reminder to finish the GI complaint you have been blaming on “something I ate.”

Treatment, sulfa allergy, and higher-risk patients

First-line drug, from CDC clinical care of cyclosporiasis: trimethoprim-sulfamethoxazole (TMP-SMX; Bactrim, Septra, Cotrim). Immunocompetent adults: one double-strength tablet (160/800 mg) twice a day for 7–10 days. Children 2 months and older: weight-based split doses for the same stretch. People with HIV often need a longer course. There is no vaccine.

Healthy people can recover without antibiotics, slowly, with relapses. That is not a reason to skip the test if you are still sick. It is a reason not to start a leftover metronidazole from a prior “GI cocktail.” CDC lists metronidazole, tinidazole, azithromycin, doxycycline, and several other common antiparasitics as ineffective against this organism. Ciprofloxacin has weak or conflicting data; CDC’s practical line for immunocompetent patients is that it does not work well. If you have a sulfa allergy, that is an allergist-and-clinician problem, not a forum substitution. Options in the CDC note are observation, limited-evidence alternatives, or desensitization in selected patients who actually need the drug.

Pregnancy: TMP-SMX is category C; avoid near term because of newborn bilirubin risk. Lactation: generally compatible with healthy full-term infants after the newborn period; avoid when nursing a premature, jaundiced, or G6PD-deficient infant. That is label-level caution, not a home protocol. A prescriber has to match the stool result to the patient.

Older adults and people on a lot of medicines should not wait out a month of diarrhea because “it’s just a parasite.” Dehydration is how this file got two deaths in people who already had other diagnoses. If you are sorting 2027 plan paperwork anyway, keep the outbreak printout next to the Medicare ANOC / open enrollment folder so the next clinic visit has dates, meals, and the CDC URL in one place.

What to do in the kitchen now

Recalled bags should not be in a refrigerator in late August. If a Marketside iceberg salad or shredded pack with those July 18–Aug. 3 dates is still in a garage fridge or a restaurant walk-in, discard it. Clean and sanitize surfaces and containers it touched. FDA’s outbreak page repeats that instruction because shreds stick to lids and crisper drawers. A wipe is not enough if the bag leaked.

Do not compost recalled lettuce in a home pile you later put on tomatoes. Trash it. Foodservice operators with leftover invoices from late June–mid-July should still match the SKU table in the company notice, even if the bags are long gone — that is how a health department interview gets a useful answer instead of “we buy lettuce.”

Fresh iceberg from a different grower is not this recall. It is also not a promise. CDC’s outbreak page says Cyclospora can ride on many kinds of produce. Wash, refrigerate cut product within two hours, cook when the dish allows. A cooked taco filling is a different risk than a cold shredded garnish. That is why this outbreak ran through chopped and shredded foodservice packs instead of a whole-head display.

The rest of the national pile

This lettuce file is a subset. CDC is still investigating other cyclosporiasis that is not Taylor Farms iceberg. AP’s Friday wrap, citing CDC earlier this week, put the national 2026 pile near 29,000 confirmed or suspected cases and 922 hospitalizations — versus a previous U.S. high around 4,700 in 2019. Those national numbers include this outbreak and everything else. Do not add 11,458 to 29,000. The 11,458 is inside the bigger seasonal mess.

July’s HAN is the clinician origin story: by mid-July CDC already had 1,645 confirmed domestic cases since May 1, against 249 in the same window of 2025, plus more than 5,100 reports still being sorted. Median age 44, 56% female, 9% hospitalized in that early confirmed slice, 34 states represented even before this lettuce traceback closed. The cyclospora outbreak on iceberg is the piece with a named farm, a recall, and a restaurant chain in the interview notes. The rest of the 29,000 is why a negative lettuce history does not end the test request if the diarrhea matches.

Household job from Thursday’s numbers: if the recalled bag is gone, stop hunting it. If the stools are not gone, get the specific test. If a health department calls about meals from two weeks before you got sick, answer the phone — that interview is how Georgia, Tennessee, and Texas showed up on this week’s map. The investigation stays open. The count will move again. The lettuce from this farm should not.

Informational only — not medical advice. Confirm symptoms, testing, and treatment with a clinician. Do not start or stop antibiotics from a headline. Check the live FDA and CDC outbreak pages for case counts; they change.
