Multiple Twin Sisters Creamery cheese products have been recalled following an E. coli outbreak in Washington and Oregon. To date, two adults and one child have reported illnesses linked to the outbreak.
On October 25, 2025, Twin Sisters Creamery recalled Whatcom Blue, Farmhouse, Peppercorn, and Mustard Seed varieties of its 2.5-pound round cheese wheels. The cheese wheels were sent to distributors in Washington and Oregon. Some products were further distributed to retail stores for repacking or sold as pre-cut, half-moon-shaped pieces.
The products are made with raw, unpasteurized milk and may be contaminated with Shiga toxin-producing Escherichia coli (STEC) and Escherichia coli O103.
Third-party testing of Farmhouse cheese samples confirmed the presence of E. coli O103. Whatcom Blue samples analyzed by the FDA and the Washington State Department of Agriculture tested positive for E. coli STEC.
On October 26, 2025, Washington State-based food distributor Peterson Company recalled half-moon-shaped pieces of Farmhouse, Whatcom Blue, and Twin Sisters Creamery cheeses after Twin Sisters Creamery notified them of the three reported STEC infections.

Three infections linked to the E. coli outbreak
There have been three reports of STEC infections caused by E. coli O103 to date, one in Oregon and two in Washington. One of the three reported infections involved a young child.
An infected Oregon resident consumed Twin Sisters Creamery Farmhouse cheese before becoming ill. The Washington State Department of Health, Oregon Health Authority, and federal authorities are investigating the outbreak.
E. coli can cause STEC infections
You can get an STEC infection by eating foods contaminated by E. coli.
Symptoms may include diarrhea, stomach cramps, or blood in the stool. Symptoms typically appear 1 to 10 days after exposure.
The FDA recall notices explain that STEC infection can lead to Hemolytic Uremic Syndrome (HUS), which is a life-threatening condition that can cause kidney failure and have fatal complications. HUS is particularly dangerous for young children, elderly adults, and immunocompromised people.
