--- title: What is E. coli? date: 2026-07-05T09:43:00-07:00 author: Bill Marler canonical_url: "https://marlerclark.com/news_events/what-is-e-coli" section: News --- [All News](/news_events) / [Firm News](https://marlerclark.com/news_events/firm-news) / # What is E. coli? ***E. coli*** *E. coli* O157:H7 is the pathogen that built this firm. In its worst form it produces a Shiga toxin that shuts down the kidneys—[hemolytic uremic syndrome (HUS)](https://about-hus.com/)—and its victims are too often children. [Marler Clark, The Food Safety Law Firm](https://marlerclark.com/), is the nation’s leading firm for [*E. coli*](https://about-ecoli.com/) and HUS cases. Our [*E. coli* lawyers](https://marlerclark.com/food-litigation/e-coli-o157h7-outbreak-litigation) have stood beside thousands of families in the only U.S. law practice devoted exclusively to foodborne illness, which has recovered more than $850 million for victims and families nationwide. We have traced [*E. coli*](https://about-ecoli.com/) to ground beef, raw milk, lettuce, spinach, sprouts, and much more, and we have brought cases against Jack in the Box, Dole, ConAgra, Cargill, and Jimmy John’s. Among those we have been honored to represent are [Brianne Kiner](https://marlerclark.com/news_events/jack-in-the-box-e-coli-outbreak-western-states),[Stephanie Smith](https://marlerclark.com/news_events/cargill-e-coli-outbreak-minnesota), and [Linda Rivera](https://marlerclark.com/news_events/multi-state-e-coli-o157h7-outbreak-linked-to-uncooked-nestle-toll-house-coo). Our advocacy has reached beyond the courtroom as well: we helped push the federal government to declare *E. coli* O157:H7—and later six additional Shiga toxin–producing strains—adulterants in ground beef, and we have funded independent research into the pathogen to push the science forward. If you or a family member developed an [*E. coli*](https://about-ecoli.com/) infection or HUS after eating contaminated food and you want to understand your legal options, contact the Marler Clark [*E. coli*](https://about-ecoli.com/) attorneys for a free case evaluation. **FAQ** **What is *E. coli*?** *E. coli* O157:H7 is a Shiga toxin–producing strain of *Escherichia coli* that causes severe, sometimes life-threatening food poisoning. Most people develop painful stomach cramps and bloody diarrhea three to four days after exposure, and about 5 to 10 percent of victims—often young children—go on to develop hemolytic uremic syndrome (HUS), a form of acute kidney failure. **What foods cause *E. coli* outbreaks?** Ground beef, raw milk, leafy greens such as romaine and spinach, sprouts, unpasteurized juice, and raw flour have all been linked to *E. coli* O157:H7. Any food contaminated with even a trace of cattle feces can carry it. **What is HUS, and is it permanent?** Hemolytic uremic syndrome is the most common cause of acute kidney failure in young children. Many children recover, but some are left with lasting kidney damage, high blood pressure, or neurological injury and need lifelong monitoring. **Can I sue if I got *E. coli* from food?** If a contaminated food caused your infection, you may have a product-liability claim against the manufacturer, grower, or restaurant. The key questions are what you ate and whether your illness is genetically linked to a known outbreak strain. **How long do I have to file an *E. coli* lawsuit?** Filing deadlines (statutes of limitation) vary by state and by the type of injury, and they can run quickly. A free case evaluation is the fastest way to learn where you stand. **Additional Resources:** - • [About *E. coli*](https://about-ecoli.com/) — a complete online resource on the symptoms and risks of
