Symptoms can range from mild to severe and typically appear 3 to 4 days after exposure. Common symptoms include abdominal cramps, diarrhea (which may be bloody), vomiting, and sometimes fever. In severe cases, especially with Shiga toxin-producing E. coli (STEC) strains, complications such as Hemolytic Uremic Syndrome (HUS) can occur, leading to kidney failure.
