In the last twenty-four hours, two people have called my office. Both have culture-confirmed E. coli. Both have been told they are part of a multistate E. coli outbreak linked to a food that has not been named. When each of them went back through what they ate before they got sick, the same item came up: a sandwich wrap, meat and vegetables, bought at the same store. The same chain, that is. The two of them live in different states.
Two phone calls are not an epidemiologic study, and I am not naming the store. I do not have what the agencies have. The two epidemiologists on my staff are working on the link between the two callers now. They have ordered the state and local health department records on both, along with records from CDC, FDA and FSIS, and there will be more to say once those come in. What I have today is two interviews that line up with a file I wrote about last week, and they line up well.
What the three federal pages say today
FDA’s CORE table, stamped September 25, carries reference #1421: E. coli O157:H7, 25 sick, product not yet identified, traceback initiated, no inspection, no sampling. The row carries USDA’s reference number, 2026-04, and it is the only active row on FDA’s table with one. FSIS’s outbreak table lists 2026-04 as a September investigation, product Unknown, with a note that FSIS and FDA are investigating it together. It is the only active investigation FSIS has posted all year. CDC’s weekly page, last updated September 23, counts six active multistate E. coli investigations and names none of them. No states, no onset dates, no hospitalizations, no ages. I went through all three pages this morning.
What being told you are part of an outbreak means
When a health department tells someone, they are part of a multistate outbreak, it is not the patient’s guess, and it is not the health department’s either. The patient’s stool culture grew E. coli. A public health laboratory sequenced the bacteria’s genome and uploaded the result to PulseNet, CDC’s national database of DNA fingerprints. The sequence matched the cluster. Then came the questionnaire: everything eaten in the week before illness, every store, every restaurant. My two callers answered that questionnaire in different states, and gave the same answer, before either of them talked to me.
CDC’s own timing rule matters here. Its outbreak pages say it usually takes three to four weeks to determine whether a sick person is part of an outbreak. A count posted on September 23 is made of people who got sick weeks earlier. The people whose sequences are matching this week are the next update.
Why a wrap explains the two reference numbers
Last week I laid out how FDA and USDA divide the food supply: meat and poultry to FSIS, everything else to FDA, a percentage formula for foods that contain both, and sandwiches as the standing joke. The joke is more specific than most people know. FSIS’s own directive says closed-face sandwiches, a meat or poultry filling between two slices of bread, a biscuit or a bun, are FDA’s, a decision the agencies trace to the 1930s. Wraps are different. When wrap makers argued that a wrap is close enough to a closed-face sandwich to be FDA’s too, FSIS disagreed: wraps were new, the old sandwich decision did not cover them, and a wrap with meat is a meat product, like a burrito. The two agencies put that in the Federal Register in November 2005, alongside a proposal, then under consideration, to move closed-face sandwiches to FSIS. The move never happened. Twenty-one years later the sandwich is still FDA’s, and FSIS’s stated position on a wrap with meat is that it is a meat product.
Now put a meat-and-vegetable wrap on the traceback desk. The turkey or roast beef or chicken inside it came from an FSIS-inspected plant. The lettuce, the tomato, the onion and the tortilla are FDA’s. If the wrap was assembled in the store’s own kitchen, the store is a retail operation under state or county inspection, and the traceback runs to its suppliers on both sides of the line. If it came in sealed from a manufacturer, that plant belongs to one agency or the other, but its ingredients still came from both. Either way, one sick person’s wrap produces two traceback questions, one to a meat supplier and one to a produce supplier, and neither agency can close its file until its half is ruled out. That is a file with two numbers on it. It is what #1421 looks like on paper.
The last time both agencies had a sandwich file
The last joint file before this one, #1305, carried USDA 2025-06, and FDA’s own closing summary of it is titled Deli Sandwich (suspect). That was the Fresh & Ready Foods Listeria outbreak: ready-to-eat sandwiches and snack items, turkey and cheese, ham and cheese, beef cheesesteak, sold at convenience stores, hospitals, hotels, airports and airlines in Arizona, California, Nevada and Washington. Ten people sick, all ten hospitalized, one dead. Here is the part worth remembering. FDA and CDC investigated that cluster in 2024 and could not identify a source; the specimens dated from December 2023 to September 2024. The answer came in April 2025, when FDA inspectors on a routine visit found Listeria in the San Fernando plant and the sequence matched the outbreak strain. The public heard the company’s name in May 2025, and even then, the summary says the sandwich was never confirmed as the vehicle; it remained the suspect. A joint file is no guarantee of an answer, and a routine inspection, not the traceback, is what found the strain in the last one.
What an announcement without a food looks like
The agencies do not need a brand name to say something. On October 28, 2020, FDA announced two E. coliO157:H7 outbreaks, 23 sick in one and 21 sick with one death in the other and said in so many words that it did not know what food was making people sick or whether that food was even FDA-regulated. It called the announcement early communication, and it promised a new web resource for early updates on active investigations. The clusters were posted as Unknown Source 1, 2 and 3, with the states listed. The table FDA keeps today grew out of that promise. It posts the count and withholds the states.
What I am asking for is what I asked for last week, plus one item. Say which states. Say the onset dates. Say whether the suspect food is a mixed product, and which ingredient each agency is tracing. And if a sandwich wrap is on the traceback desk, say so now, because a wrap sold this afternoon will take three to four weeks to show up in PulseNet. In October 2024, FDA, FSIS and CDC announced the McDonald’s Quarter Pounder outbreak while the onions and the patties were still being sorted out, and McDonald’s pulled both the same day. The public was told what was in play. That is the standard, and it was met two years ago.
To the people who are calling
The two people who called did the right things first. They went to a doctor, they were tested, and they went back through their food history item by item. If you have been told you are part of this outbreak, do the same, and keep the receipt, the loyalty-card record and any packaging that is left; write down the date and the store. Interviews are how outbreaks get solved. The percentages that put McDonald’s onions and patties side by side in 2024 came from them.
I have represented people sickened by E. coli since 1993. My hamburger cases went away because FSIS declared O157:H7 an adulterant in ground beef in September 1994; since about 2000, most of my E. coli cases have been lettuce. A meat-and-vegetable wrap is both halves of that history in one package. Last week I asked which side of the jurisdictional line this outbreak was on. Two phone calls suggest the answer is both, and that the reason no food has been named may be that the food is a sandwich. Twenty-five was the count on September 23. It is a floor. The agencies know what they are tracing. The rest of us are finding out one phone call at a time, and my epidemiologists and I will report what the records show.
