E. coli in Iowa
E. coli (Escherichia coli) are bacteria found in intestines. While most strains are harmless, some cause severe food poisoning with bloody diarrhea. The most dangerous strain, E. coli O157:H7, produces toxins causing kidney failure, especially in children. Track E. coli activity and outbreaks specific to Iowa.
What is E. coli?
Most E. coli strains are part of healthy gut flora. However, Shiga toxin-producing E. coli (STEC), particularly O157:H7, cause approximately 265,000 illnesses annually in the U.S. About 5-10% of diagnosed cases develop hemolytic uremic syndrome (HUS), a life-threatening kidney condition. Undercooked ground beef, contaminated produce, and unpasteurized dairy are common sources.
Symptoms
- Severe stomach cramps
- Diarrhea (often bloody)
- Vomiting
- Mild fever (usually <101°F)
- Symptoms last 5-10 days
- HUS warning signs: Decreased urination, extreme fatigue, pale skin, bruising
Transmission
Eating contaminated food (ground beef, raw produce, unpasteurized dairy); contaminated water; person-to-person (poor hygiene); contact with infected animals
Contagious Period: While bacteria present in stool (can persist weeks after recovery); requires good hygiene
Prevention
- Cook ground beef to 160°F (use food thermometer)
- Avoid raw milk, unpasteurized juice, and raw cookie dough
- Wash hands thoroughly after bathroom, changing diapers, before preparing food
- Wash fruits and vegetables under running water
- Avoid cross-contamination (separate raw meat from produce)
- Don't swallow water when swimming in lakes, pools, or water parks
- Keep children with diarrhea out of swimming areas and daycare
- Avoid preparing food for others when ill
