Investigation of Salmonella Enteritidis Outbreak Associated with Truffle Oil - District of Columbia, 2015.

On September 8, 2015, the District of Columbia Department of Health (DCDOH) received a call from a person who reported experiencing gastrointestinal illness after eating at a District of Columbia (DC) restaurant with multiple locations throughout the United States (restaurant A). Later the same day, a local emergency department notified DCDOH to report four persons with gastrointestinal illness, all of whom had eaten at restaurant A during August 30-September 5. Two patients had laboratory-confirmed Salmonella group D by stool culture. On the evening of September 9, a local newspaper article highlighted a possible outbreak associated with restaurant A. Investigation of the outbreak by DCDOH identified 159 patrons who were residents of 11 states and DC with gastrointestinal illness after eating at restaurant A during July 1-September 10. A case-control study was conducted, which suggested truffle oil-containing food items as a possible source of Salmonella enterica serotype Enteritidis infection. Although several violations were noted during the restaurant inspections, the environmental, laboratory, and traceback investigations did not confirm the contamination source. Because of concern about the outbreak, the restaurant's license was suspended during September 10-15. The collaboration and cooperation of the public, media, health care providers, and local, state, and federal public health officials facilitated recognition of this outbreak involving a pathogen commonly implicated in foodborne illness.

Sorting through the lost and found: are patient perceptions of engagement in care consistent with standard continuum of care measures?

BACKGROUND: Indicators for determining one's status on the HIV care continuum are often measured using clinical and surveillance data but do not typically assess patient perspectives. We assessed patient-reported care status along the care continuum and whether it differed from medical records and surveillance data. METHODS: Between June 2013 and October 2014, a convenience sample of clinic-attending HIV-infected persons was surveyed regarding care-seeking behaviors and self-perceived status along the care continuum. Participant responses were matched to DC Department of Health surveillance data and clinic records. Participants' care patterns were classified using Health Resources Services Administration-defined care status: in care (IC), sporadic care (SC), or out of care (OOC). Semistructured qualitative interviews were analyzed using an open coding process to elucidate relevant themes regarding participants' perceptions of engagement in care. RESULTS: Of 169 participants, most were male participants (64%) and black (72%), with a mean age of 50.7 years. Using self-reported visit patterns, 115 participants (68%) were consistent with being IC, 33 (20%) SC, and 21 (12%) OOC. Among OOC participants, 52% perceived themselves to be fully engaged in HIV care. In the previous year, among OOC participants, 71% reported having a non-HIV-related medical visit and 90% reported current antiretroviral use. Qualitatively, most SC and OOC persons did not see their HIV providers regularly because they felt healthy. CONCLUSIONS: Participants' perceptions of HIV care engagement differed from actual care receipt as measured by surveillance and clinical records. Measures of care engagement may need to be reconsidered as persons not receiving regular HIV care maybe accessing other health care and HIV medications elsewhere.
