Positive Test Raises New Questions in Dairy Probe (Image Credits: Unsplash)
Fresno, California — Federal investigators detected E. coli O157:H7 in a sample of raw cheddar cheese produced by Raw Farm LLC, a finding that connects the product to illnesses from a previous year. Whole genome sequencing revealed the bacterial strain matched patient samples from a 2025 outbreak, though it differed from the one causing current cases. This discovery emerged amid an ongoing multistate investigation into raw dairy products from the company. Health officials continue to advise against consuming the implicated cheeses as testing and recalls proceed.
Positive Test Raises New Questions in Dairy Probe
Inspectors from the Food and Drug Administration collected 19 samples of Raw Farm-brand raw cheddar cheese during facility checks.[1] One sample tested positive for the dangerous pathogen E. coli O157:H7, capable of causing severe illness. Although the contaminated cheese never reached store shelves, the result highlighted persistent risks in unpasteurized dairy production.
Advanced DNA analysis through whole genome sequencing confirmed the strain’s profile. It aligned precisely with bacteria isolated from patients in a separate 2025 outbreak, which authorities had already closed.[1] Officials noted no link to the active 2026 cluster, yet the episode underscored the challenges of pathogen control in raw milk processing.
Details of the Linked Outbreaks Emerge
The current investigation targeted nine confirmed E. coli O157:H7 illnesses spanning September 1, 2025, to February 20, 2026. Five cases occurred in California, with one each in Florida and Texas. Three patients required hospitalization, including one child who developed hemolytic uremic syndrome, a serious complication involving kidney damage.[2][1]
Interviews with eight sick individuals revealed a strong pattern: all reported consuming Raw Farm raw dairy products. Five who fell ill in 2026 ate the brand’s raw cheddar cheese, while two from late 2025 drank its raw milk. More than half the victims were children under age five, a group especially vulnerable to such infections.[3]
Recall Targets Specific Raw Cheddar Varieties
Raw Farm LLC issued a voluntary recall on April 2, 2026, after weeks of federal urging. The action covered original and jalapeno-flavored raw cheddar in blocks and shredded forms, plus bulk sizes. Products carried expiration dates through late summer 2026.[2]
Authorities distributed the cheeses nationwide, including at chains like Sprouts Farmers Market and H-E-B. Consumers faced clear directives: discard any matching items, sanitize contact surfaces, and avoid repackaged products. State labs continued testing, but no further positives tied to the current outbreak appeared as of mid-April.[1]
- 8 oz and 16 oz blocks, original flavor (exp. on/before 8/23/2026)
- 8 oz and 16 oz blocks, jalapeno flavor (exp. on/before 9/24/2026)
- 8 oz shredded original (exp. on/before 5/13/2026)
- 80 oz bulk original blocks (exp. on/before 8/11/2026)
- 80 oz bulk shredded (exp. on/before 5/6/2026)
Challenges Persist in Raw Dairy Safety
The company initially declined the FDA’s March recommendations for product removal, prompting public health alerts. Only after sustained pressure did Raw Farm proceed with the recall, which some reports described as reluctant. No pathogens had surfaced in earlier cheese tests from the outbreak period, complicating direct proof of contamination.[3]
Symptoms of E. coli O157:H7 typically include severe cramps, bloody diarrhea, and vomiting, appearing three to four days post-exposure. While most recover within a week, vulnerable populations face risks of long-term health issues. Experts repeatedly stress pasteurization’s role in eliminating such threats in milk and cheese.[2]
Key Takeaways:
- FDA found E. coli in one Raw Farm cheese sample, matching a closed 2025 outbreak but not the current one.
- Nine illnesses linked epidemiologically to Raw Farm raw dairy; recall covers multiple cheddar products.
- Children under five comprised over half the cases, with three hospitalizations reported.
This episode reinforces the inherent dangers of raw dairy, even from reputable producers, as genetic matches reveal hidden contamination histories. Public health vigilance remains essential to prevent future outbreaks. What steps do you take to ensure food safety in your home? Share your thoughts in the comments.
