Oregon E. coli Case Linked To Washington Cheese – KXL

PORTLAND, OR – The Oregon Health Authority reports that an Oregon resident is one of three people who tested positive for E. Coli bacteria after eating unpasteurized aged cheese produced at the Twin Sisters Creamery Farmhouse in Washington state.

Samples of leftover cheese obtained from the Oregon resident were tested at a laboratory, and those tests confirmed the presence of  the same E. coli pathogen that was found in two Washington state residents who had indirect exposure to cheese from the same company.  All three people experienced symptoms of E.coli infection between September 5th and September 16th. 

All sizes of Whatcom Blue, Farmhouse, Peppercorn and Mustard Seed varieties of aged cheese from Twin Sisters Creamery produced on or after May 27, 2025, are being recalled.
