E. coli Outbreak tied to Organic Yogurt
The Washington State Department of Health (DOH) is working with local health jurisdictions to respond to a multi-county outbreak of E. coli O157:H7 that may be linked to fresh produce.
The outbreak currently includes six confirmed cases across Benton County (1), King County (3), Snohomish County (1) and Walla Walla County (1). DOH is only reporting confirmed cases infected with bacteria that have been genetically linked, but local health officials may report higher numbers for their counties that include cases still under investigation.
There is one case in the outbreak between ages 0-9, two cases age 10-19, one case age 20-29, one age 30-39, and one case age 70-79. Three cases have been hospitalized and one case developed hemolytic uremic syndrome (HUS). HUS is a serious complication of E. coli O157:H7 infection that can damage the kidneys and other organs. The earliest case in the outbreak started having symptoms March 9, and the most recent case had symptoms starting April 21.
The Snohomish Health District announced Tuesday evening that it has identified two cases of Shiga toxin-producing E. coli (STEC) in Snohomish County residents. Following public health interviews, these cases do appear to be connected to a cluster of STEC cases among seven children in King County.
The local cases involve a woman in her 20s and a child under 10 years of age from separate households. The child has been hospitalized, but no further information will be shared on the cases due to patient privacy.
Seattle King County Public Health is investigating a cluster of seven children infected with Shiga toxin-producing E. coli (also known as STEC) in King County. All cases are currently under 15 years of age, and three are under 5 years of age. Cases have been reported during April 22–May 1, 2021.
All 7 children developed symptoms consistent with STEC, including diarrhea (often bloody), abdominal cramping, nausea, and vomiting. Illness onsets occurred during April 17–29, 2021. Six children have been hospitalized; this includes two children who developed a type of kidney complication called hemolytic uremic syndrome (HUS) and both are recovering.
