Alfalfa Sprout Outbreak Links Minnesota Grower to Multistate Salmonella and E. coli Illnesses
8/21/2026, 10:02:55 PM
Core Event: Multistate Food-Poisoning Outbreak
Health officials in Minnesota and Wisconsin have confirmed a multistate outbreak of Shiga toxin-producing E. coli (STEC) and Salmonella infections tied to alfalfa sprouts sold under the Calco and Everything Sprouts brands. The Minnesota Department of Health reports 23 illnesses with two hospitalizations; Wisconsin authorities report 17–18 illnesses with one hospitalization. Illness onset dates span July 8 – August 8, 2026.
Background & Context
Everything Sprouts, a Minneapolis-based grower, received a federal warning letter on March 28, 2025 after an inspection covering Oct 30 – Nov 14, 2024 that cited roof leaks and contaminated water sources. Earlier inspections noted sanitary concerns but involved other sprout varieties. The current outbreak involves alfalfa sprouts, which were not specifically mentioned in the 2025 warning.
Data & Statistics
- Minnesota: 23 confirmed cases; 2 hospitalized.
- Wisconsin: 17 confirmed cases (one source lists 18); 1 hospitalized.
- Pathogens: Multiple STEC strains (O103:H25, O26:H11, O168:H8) and Salmonella.
- Symptoms: Bloody diarrhea, severe cramps, fever; STEC can cause hemolytic uremic syndrome (HUS).
- Baseline: Minnesota averages ~1,000 Salmonella and 85 STEC infections annually; CDC estimates many undetected cases per confirmed patient.
Official Statements & Responses
- Minnesota Department of Health: “The illnesses have been linked to eating alfalfa sprouts produced by Everything Sprouts… consumers should discard any Calco or Everything Sprouts alfalfa sprouts.”
- Wisconsin Department of Health Services: Advises residents to check homes for the implicated sprouts, discard them, and monitor for symptoms.
- FDA: Initiated inspection and sample collection at Everything Sprouts and is working with the company on a potential recall; no formal recall yet.
- CDC: Provides guidance on STEC and Salmonella symptom onset and highlights HUS risk for children, older adults, and immunocompromised individuals.
Why It Matters
STEC infections can progress to HUS, a life-threatening condition causing kidney failure and long-term organ damage. Salmonella can lead to severe dehydration and bloodstream infection, especially in vulnerable populations. The presence of two pathogens in a single product raises concerns about sprout production practices.
Conflicting Reports & Gaps
- Wisconsin case count: Most outlets report 17 cases; one source lists 18. Both agree on a single hospitalization.
- Recall status: No recall has been initiated despite FDA’s inspection.
- Source of contamination: Investigators have not identified a definitive contamination point; prior violations involved other sprout types.
What's Next
State health departments, the CDC, and the FDA will continue joint investigations to pinpoint the contamination source and assess the need for a formal recall. Consumers should discard any Calco or Everything Sprouts alfalfa sprouts and seek medical attention if gastrointestinal symptoms develop. Ongoing surveillance will track additional cases across other states.
