Raw Milk Cheese Linked to Multistate E. coli Outbreak
By Drooid · · How we work
Outbreak Overview
Federal health agencies are investigating a multistate outbreak of Shiga toxin-producing *E. coli* O26:H11 linked to Sierra Nevada Graziers grass-fed raw milk cheese. As of the September 25 announcement, the CDC confirmed 13 illnesses in nine states; eight required hospitalization and three progressed to hemolytic uremic syndrome (HUS). The median age of patients is five years, with more than half <= 5 years. Illness onset dates range from July 7 through late August 2026. No deaths have been reported.
Background on Raw Milk Cheese Regulation
U.S. law permits interstate sale of raw-milk cheese only if it has been aged at least 60 days, a rule dating to the 1940s. The FDA announced in 2013 that it would reevaluate the scientific basis for the rule, but a revised rule has not been issued. Food-safety attorney William D. Marler notes this is the fourth outbreak in thirty-one months involving cheese that met the 60-day requirement.
Timeline of Key Events
- July 7 – Earliest symptom onset among confirmed cases.
- September 24 – FDA contacts Sierra Nevada Cheese Company; the company initiates a voluntary recall of all Graziers raw-milk varieties.
- September 25 – CDC and FDA publicly announce the outbreak and issue consumer safety guidance.
Data and Statistics
- Illnesses: 13 confirmed.
- Hospitalizations: 8.
- HUS cases: 3.
- Age distribution: Median age 5; > 50 % <= 5 years.
- Geographic spread: CA, CO, GA, KY, MI, NV, OR, TN, UT.
- Products recalled: Medium cheddar, sharp cheddar, jalapeño jack, Monterey jack in 8-oz, 16-oz packages and 5-lb loaves.
Official Statements & Responses
- FDA: Advises consumers to discard the recalled cheese, return it for a refund, and sanitize any surfaces it contacted. The agency continues to investigate the contamination source.
- County Public Health Officer Sayone Thihalolipavan, MD, MPH: Highlighted the rapid epidemiologic detection that prompted the recall.
Verbatim Quotes
- “This is the fourth outbreak in thirty-one months linked to raw milk cheese that met FDA’s 60-day rule,” — William D. Marler
- “We are deeply grateful for the rigorous work of our epidemiology team, whose swift detection helped bring this recall to light,” — County Public Health Officer
Conflicting Reports & Gaps
- Source of contamination: Investigators have not identified the specific point of contamination, and no positive test of the cheese has been reported.
- Case count uncertainty: CDC estimates that for every confirmed case, up to 26 additional infections may go undetected, suggesting the true number of illnesses could be higher than 13.
What’s Next
- Petition outcome: The FDA must respond to Marler’s petition, which requests a mandatory warning label and an explanation of the 60-day rule within one year.
- Ongoing investigation: FDA and CDC will continue sampling, genetic analysis, and traceback efforts to pinpoint the contamination source and assess other potentially affected products.
- Public health monitoring: Agencies will update case counts as additional illnesses are identified and maintain advisories regarding raw-milk cheese consumption.
