Deschutes County Health Services, the Oregon Health Authority and other partners are investigating a possible multistate outbreak of Salmonella Enteritidis infections. A health advisory asks clinicians to watch for compatible illness, collect detailed exposure histories and arrange follow-up cultures after positive screening tests. Officials have not identified a source, case count or the other states involved.

Deschutes County Health Services, working with the Oregon Health Authority and other partners, is investigating a possible multistate outbreak of Salmonella Enteritidis infections, according to a Health Alert Network advisory to health care providers in Deschutes County and nearby Central Oregon communities. The advisory asks clinicians to look for compatible illness and gather information that could help investigators connect cases; it does not identify an outbreak source or say how many people are sick.

The advisory asks clinicians to consider salmonellosis in patients with diarrhea, which can sometimes be bloody, fever and abdominal cramps. Providers are asked to take a food and other exposure history covering the five days before symptoms began, the period specified in the notice.

Investigators want details about eggs and foods made with eggs, including fresh or locally sourced eggs, and raw, unpasteurized milk. The advisory also calls attention to contact with animals such as chickens and baby chicks, lizards, snakes and turtles. Clinicians are asked to record restaurant names and locations, along with the dates of meals, so investigators can compare exposures across patients.

For patients with diarrhea, the county asks providers to consider stool testing. If a culture-independent test, such as PCR, detects Salmonella, the advisory says a reflex culture or specimen submission should follow. Public health laboratories need an isolate to characterize the bacteria and support whole genome sequencing, a method that can help determine whether infections are related.

The developmentDeschutes County health officials issued a clinical advisory as Oregon agencies investigate a possible multistate Salmonella Enteritidis outbreak.

How Patient Samples Can Link Cases

The advisory is an early investigative step, not a public identification of a contaminated food or business. Its practical importance is that clinical histories and laboratory samples can help public health teams decide whether people who became ill in different locations share an exposure or are part of the same outbreak.

Without a bacterial isolate, the laboratory cannot perform the sequencing described in the advisory. That can limit investigators’ ability to compare infections in Central Oregon with cases elsewhere. Accurate exposure records also give investigators a basis for checking whether patients ate at the same restaurant, handled similar foods or had contact with animals.

For residents, the notice signals that officials are looking for possible cases, but it does not establish that any particular food or animal is responsible. The listed exposures are questions for investigators to pursue, not findings that those items caused illness. No recall, venue warning or consumer instruction is included in the source report.

The Investigation’s Current Scope

The source report, published by Food Safety News on October 12, 2026, says the advisory was sent to providers in Deschutes County and surrounding Central Oregon communities. It describes the investigation as involving multiple states, but does not name those states or provide a case total.

The public health response described so far centers on case detection and information gathering: clinicians are asked to recognize symptoms, document exposures and report suspected or confirmed cases. Laboratory follow-up is part of the same effort, because a positive screening result alone may not provide the isolate needed for further characterization.

The advisory gives reporting contacts for Deschutes, Crook and Jefferson counties, as well as the Oregon Health Authority. Those instructions are directed to health care providers. The available report does not describe an identified common meal, supplier or other confirmed source, nor does it give a timeline for when investigators expect to reach a conclusion.

“The county is investigating a multistate outbreak of Salmonella Enteritidis infections.”

Source and Case Count Not Disclosed

The available report does not state how many people are ill, which other states are involved, when the first illness began or whether cases have been confirmed as part of one outbreak through laboratory analysis. It also does not name a food, restaurant, animal contact or supplier as the source.

Eggs, unpasteurized milk, animal contact and restaurant meals appear in the advisory as exposure topics providers should ask about. Their inclusion does not confirm a link to the infections. The report also does not specify whether officials have issued any separate consumer notice, product recall or business warning.

Case Reports and Laboratory Follow-Up

Health care providers are being asked to assess patients with compatible symptoms, collect exposure histories and consider stool testing. Suspected or confirmed cases should be reported to the relevant public health agency: Deschutes County at 541-322-7418, Crook County at 541-447-5165, or Jefferson County at 541-475-4456 during business hours and 541-475-2201 after hours. The advisory also lists the Oregon Health Authority at 971-673-1111.

After a positive culture-independent Salmonella test, the requested culture or specimen submission can allow public health laboratories to characterize the isolate and conduct sequencing. The source report does not give a date for a further update. Any confirmed common exposure, case count or additional public guidance remains dependent on information from the ongoing investigation.

Key Questions

What are Oregon officials investigating?

Deschutes County Health Services, the Oregon Health Authority and other partners are investigating a possible multistate outbreak of Salmonella Enteritidis infections. The report does not provide a case count or identify the other states.

Has officials’ investigation identified a food source?

No source is named in the available report. Providers are asked to ask about several possible exposures, including eggs, unpasteurized milk, animal contact and restaurant meals; these are investigative questions, not confirmed causes.

What symptoms does the advisory ask clinicians to watch for?

The advisory highlights diarrhea, sometimes bloody, fever and abdominal cramps. It asks providers to consider stool testing for patients with diarrhea.

Why does a positive PCR test need follow-up?

The advisory calls for a reflex culture or specimen submission after a positive culture-independent test. This can provide an isolate for laboratory characterization and whole genome sequencing, which may help determine whether infections are linked.

How many people are sick, and when will officials update the public?

The report gives no case count, update schedule or expected investigation timeline. Those details, along with the states involved and any common exposure, remain unknown from the available information.
