The FDA is counting 116 salmonella cases and still has not named the food

The FDA’s outbreak investigation table lists 116 cases in a Salmonella Newport outbreak, reference number 1403, and the column where the contaminated food should appear reads Not Yet Identified. The table was last updated September 30, and the investigation is marked active.

The 116 belongs to one outbreak. Two other open Salmonella investigations on the same table also have no named product, and the count for the Newport cluster has been climbing, with Food Safety News reporting it rose from 111 to 116 in a single week.

Reference 1403 on the FDA table

According to the FDA’s Investigations of Foodborne Illness Outbreaks page, the list covers outbreaks and adverse event investigations “primarily being managed by FDA’s CORE Response Teams.” Reference 1403 reads Salmonella Newport, product Not Yet Identified, 116 cases, active. Food Safety News, in its report on the table’s newest entries, put the start of the investigation at August 26 and noted that the agency had begun sampling without releasing details.

The page, as retrieved, gives no breakdown of where the sick people live, when they became ill or how old they are, and no recall or consumer advisory is attached to the row. Without a named product there is nothing for a household to check in the refrigerator or pantry.

Salmonella and Listeria rows with no product

Reading the table as a whole gives context for the 116. Newport is the largest of the unresolved Salmonella files by count, but it is one of several, and the table also carries Cyclospora investigations, an E. coli O157:H7 cluster that grew from 25 to 38 cases, and an E. coli O26:H11 outbreak linked to raw milk cheese.

Outbreak 1403 is not alone. The same table lists Salmonella Oranienburg, reference 1387, at 99 cases, and a third Salmonella strain, reference 1402, at 43 cases, both with the product Not Yet Identified. A Listeria monocytogenes investigation, reference 1417, stands at 44 cases, also without a product, and another Listeria row, 1415, has 11. In all, 11 of the 16 rows on the September 30 table list the food as not yet identified.

Other rows show what a resolved identification looks like. Reference 1395, a Salmonella Javiana outbreak, is tied to jalapeno peppers, and reference 1411, Salmonella Bovismorbificans, is tied to sprouts. On the CDC side, the broccoli sprouts investigation reports 32 cases in six states as of September 24, with the product named as broccoli sprouts produced by Evergreen Fresh Sprouts LLC and a September 10 company recall of 215 cases. A named food lets investigators warn buyers directly, and reference 1403 has not reached that point.

CORE and the traceback step

The FDA created its Coordinated Outbreak Response and Evaluation network, CORE, in 2011. In the agency’s overview of the program, CORE has evaluated more than 1,300 potential outbreaks and responded to more than 350 tied to FDA-regulated foods, identifying a specific culprit in over 200 of them. Its toolkit combines epidemiologic analysis of illness patterns, laboratory work such as whole genome sequencing to link cases, facility inspections and product sampling along the supply chain.

Traceback is the step that usually names the food. Investigators work through supply chain data to find the source of the food sold or served where sick people ate, and the FDA’s overview notes that products with international supply chains bring language barriers and document gaps. Outbreak 1403 is described by Food Safety News as having sampling begun, which is the stage at which a product either emerges or does not. The FDA also lists a newly started traceback for the Listeria cluster, reference 1415, showing that the agency runs several of these searches at the same time, each at a different stage.

Salmonella symptoms and the confirmed-case count

The CDC’s symptom guidance says most people have watery diarrhea and severe stomach cramps, usually starting 6 hours to 6 days after infection and clearing in 4 to 7 days. It advises seeking care for diarrhea or vomiting lasting more than two days, bloody stool, a fever above 102 degrees Fahrenheit or signs of dehydration. Complications are rare but can include infection spreading to blood, bones, joints or the brain, and some people develop reactive arthritis that can last years, according to the same guidance. The agency estimates 1.35 million Salmonella infections occur in the United States each year, with only about 1 in 30 diagnosed, so a count like 116 reflects only the cases that were confirmed and linked to the cluster, a floor rather than a ceiling on how many people were actually sickened.

For reference 1403 the record is plain: 116 cases on the table’s September 30 update, an active investigation that began in late August, and no food named by the FDA. A change in either the count or the product column would appear first in that table.
