E. coli Outbreak 2026
About This E. coli
What is this E. coli?
E. coli is a large family of bacteria, most of it harmless. This outbreak involves a Shiga toxin-producing type, O26, which can cause severe, sometimes bloody diarrhea and, in some people, kidney failure. It usually spreads through contaminated food. Raw (unpasteurized) milk and cheese are a known risk because they skip pasteurization, the heat step that would kill the bacteria.

Treatments & Vaccines in Development
Most people recover from this E. coli with rest and fluids. Antibiotics are usually avoided because they can worsen the kidney complication, and there is no vaccine. Here is what care looks like.
Most healthy people with this kind of E. coli recover on their own in about a week. The key is staying hydrated, since the real danger is fluid loss from diarrhea and vomiting. Rest, fluids and monitoring for warning signs are the mainstay of care.
CDC E. coli →For Shiga toxin-producing E. coli like O26 and O145, doctors usually avoid antibiotics. In this type of infection antibiotics can raise the risk of hemolytic uremic syndrome, the dangerous kidney complication, rather than help. Anti-diarrheal medicines are also discouraged for the same reason. Treatment focuses on fluids and close monitoring instead.
CDC clinical guidance →There is no vaccine for this kind of E. coli. Prevention comes down to food safety: avoid recalled products, cook thoroughly, and wash hands, produce and surfaces. Raw (unpasteurized) milk and cheese are a known risk because they skip pasteurization, the heat step that would kill the bacteria.
