Health officials in Seattle and King County are investigating a salmonellosis outbreak caused by Salmonella Stanley, an uncommon strain of Salmonella bacteria.
Six persons infected with Salmonella Stanley were reported to Public Health during July 17–July 24. On July 26-27, genetic fingerprinting results for four of the six cases became available, and all had the same genetic fingerprint, suggesting that they have some common source of infection; genetic fingerprinting for the other two cases is pending.
This fingerprint has only been seen twice before in King County where two to six cases of Salmonella Stanley have been reported annually over the past several years. Public Health is attempting to interview each case to gather information about possible risk factors for infection. The source of the outbreak is still under investigation.
