On the night of Wednesday, August 23, 2023, the University of Arkansas notified students that the Arkansas Department of Health was investigating Shiga toxin-producing E. coli (STEC) infections after roughly 100 students reported symptoms. The university said the outbreak was not believed to be connected to its public dining facilities and increased surface cleaning and sanitizing.

ADH Investigation Concludes, Source Remains Unknown The Arkansas Department of Health (ADH) confirmed this week that its investigation of an E. coli outbreak in Northwest Arkansas has concluded without a source being identified. Results from food sample tests for E. coli bacteria and surveys of sick individuals did not pinpoint a source of the August outbreak. ADH previously confirmed it has no reason to believe the outbreak is connected to the university's public dining facilities. More than 3,200 people were surveyed as a part of the investigation, which identified 37 probable cases and five confirmed cases. ADH previously confirmed that four of the confirmed cases required hospitalization but were later discharged. No new E. coli cases connected to this outbreak have been reported in Northwest Arkansas since Aug. 25.
The closure update is unusually candid: it states plainly that despite 3,200+ surveys and food testing, no single source was ever identified.
Reporting the final tally (37 probable, 5 confirmed) rather than the looser 'about 100 reported symptoms' shows the gap between symptom reports and laboratory-confirmed STEC.
Closing with a hand-hygiene reminder reframes the unresolved investigation as a routine prevention message rather than an unresolved threat.
Context

Background

Shiga toxin-producing E. coli (STEC) can cause severe illness and, rarely, hemolytic uremic syndrome, making campus outbreaks a serious public-health concern. In late August 2023, the University of Arkansas told students that the Arkansas Department of Health was investigating STEC infections among roughly 100 students. U.S. News reported four hospitalizations, and the Arkansas Democrat-Gazette described a state survey of more than 3,200 people. Food Safety News reported the investigation closed in September with 37 probable and 5 confirmed cases and no source identified. This case is distinct from the university's separate 2019 mumps outbreak and illustrates how a large symptomatic cluster can resolve without a pinpointed cause.
Analysis

Key Findings

The university pre-empted dining-hall blame by stating early that the outbreak was not believed linked to public dining facilities
Despite surveying more than 3,200 people and testing food samples, the Arkansas Department of Health never identified the source
Final laboratory-confirmed tally (5 confirmed, 37 probable) was far smaller than the ~100 students who reported symptoms
Four people were hospitalized and later discharged; the case is distinct from UARK's separate 2019 mumps outbreak
Outcome
The Arkansas Department of Health surveyed more than 3,200 people and ultimately closed the investigation in September 2023 with 37 probable and 5 confirmed cases and the source never identified; four people were hospitalized and later discharged.
