Pathogenic E. coli Outbreak with Ten Illnesses Linked to Raw Milk Cheddar Cheese

CDC and FDA are investigating an E.coli outbreak linked to raw cheddar cheese.  "As of February 16, 2024, a total of 10 people infected with the outbreak strain of E. coli have been reported from four states [CA - 4, UT - 2, CO - 3, and TX - 1]. Illnesses started on dates ranging from October 18, 2023, to January 29, 2024 (see timeline). Of 9 people with information available, 4 have been hospitalized and 1 developed hemolytic uremic syndrome, a serious condition that can cause kidney failure. No deaths have been reported.
  •  Of the 8 people interviewed, 6 (75%) reported eating RAW FARM brand raw cheddar cheese.
  • WGS showed that bacteria from sick people’s samples are closely related genetically. This suggests that people in this outbreak got sick from the same food.
  • No product samples consumed by consumers or products available for sale have tested positive for E.Coli 0157:H7.
  • Raw Farm, of Fresno CA is voluntarily recalling selected date codes of Raw Cheddar Cheese.
Because raw milk cheese is not pasteurized, the heat step is not present that would eliminate pathogens such as E. coli STEC.  Rather, aging along the presence of lactic acid bacteria (LAB) are counted on.

February 16, 2024
CDC, public health and regulatory officials in several states, and the U.S. Food and Drug Administration (FDA) are collecting different types of data to investigate a multistate outbreak of E. coli O157:H7 infections.
Epidemiologic data show that RAW FARM brand raw milk cheese is making people in this outbreak sick.

Epidemiologic Data
As of February 16, 2024, a total of 10 people infected with the outbreak strain of E. coli have been reported from four states (see map). Illnesses started on dates ranging from October 18, 2023, to January 29, 2024 (see timeline). Of 9 people with information available, 4 have been hospitalized and 1 developed hemolytic uremic syndrome, 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. This is because many people recover without medical care and are not tested for E. coli. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.

Public health officials collect many different types of information from sick people, including their age, race, ethnicity, other demographics, and the foods they ate in the week before they got sick. This information provides clues to help investigators identify the source of the outbreak.

The table below has information about sick people in this outbreak (“n” is the number of people with information available for each demographic).

Demographics InformationTable of demographic information (n is the number of people with information available)
Age  (n=10) Range from 2 to 58 years  Median age of 24 years
Sex  (n=10) 30% female  70% male
Race  (n=7) 86% White  14% Asian
Ethnicity  (n=7) 100% non-Hispanic  0% Hispanic

State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the 8 people interviewed, 6 (75%) reported eating RAW FARM brand raw cheddar cheese. This percentage was significantly higher than the 4.9% of respondents who reported eating any raw milk cheese in the FoodNet Population Survey—a survey that helps estimate how often people eat various foods linked to diarrheal illness. This difference suggests that people in this outbreak got sick from eating RAW FARM brand raw cheddar cheese.

Laboratory and Traceback Data
Public health investigators are using the PulseNet system to identify illnesses that may be part of this outbreak. CDC PulseNet manages a national database of DNA fingerprints of bacteria that cause foodborne illnesses. DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS).

WGS showed that bacteria from sick people’s samples are closely related genetically. This suggests that people in this outbreak got sick from the same food.

Public Health Actions
CDC advises people not to eat, sell, or serve RAW FARM brand raw cheddar cheese while the investigation is ongoing.

Current Update
February 16, 2024

The FDA and CDC, in collaboration with state and local partners, are investigating a multistate outbreak of E. coli O157:H7 infections linked to RAW FARM-brand Raw Cheddar cheese made by RAW FARM, LLC, of Fresno, CA.

As of February 16, 2024, a total of 10 confirmed infections have been reported from four states, including CA (4), CO (3), TX (1), and UT (2). Whole genome sequencing analysis of E. coli isolates from ill people shows that they are all closely related genetically to each other. This means that people in this outbreak are likely to share a common source of infection. Four patients have been hospitalized; one developed hemolytic uremic syndrome (HUS), a serious condition that can lead to kidney failure. No deaths have been reported.

State and local public health officials have interviewed people about the foods they ate in the week before they became ill. Six (75%) ill people reported consuming RAW FARM- brand Raw Cheddar cheese. Epidemiologic evidence shows that RAW FARM- brand Raw Cheddar cheese made by RAW FARM, LLC are the likely source of this outbreak.

In response to this investigation, RAW FARM, LLC has agreed to initiate a recall of certain lots of RAW FARM- brand Raw Cheddar cheese currently within shelf life. FDA is continuing to work with the firm to remove additional product from the market.

The investigation is ongoing to determine the source of contamination and whether additional products are linked to illnesses. FDA will update this advisory should additional consumer safety information become available.
