The Centers for Disease Control and Prevention (CDC) and public health officials in several states report investigating a multistate E. coli O157:H7 outbreak linked to Raw Farm brand raw cheddar cheese.
As of February 28, 2024, a total of 11 people infected with the outbreak strain of E. coli have been reported from 5 states— California (4), Colorado (3), Utah (2), Texas (1) and New Jersey (1).
Five people required hospitalization for their illness and 2 developed hemolytic uremic syndrome (HUS), a serious condition that can cause kidney failure. No deaths have been reported.
The true number of sick people in this outbreak is likely much higher than the number reported, and the outbreak may not be limited to the states with known illnesses.
State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the 9 people interviewed, 7 (78%) specifically reported eating Raw Farm brand raw cheddar cheese.
Officials in California, Colorado, and Utah collected various Raw Farm products for testing including raw milk, raw butter, raw cheddar cheese, and raw kefir. So far, no samples have detected E. coli. Additional testing is ongoing.
