E. coli O103 is similar to the more prevalent O157:H7 because it is a Shiga toxin-producing E. coli (STEC) bacteria.  The Shiga toxins these bacteria produce can cause serious injury or death.  E coli 0103 is part of a group of serotypes called non-O157 STEC or non-O157 E. coli.

It is more difficult to identify E. coli O103 than O157. Most health departments have to send samples to the CDC for a confirming O103 test. Because identification is difficult, E. coli O103 infections are most likely underreported.

E. coli O103 has been a cause of hemolytic uremic syndrome (HUS) in Europe and the United States. HUS can cause any of the following:

  • Hemolytic Anemia
  • Hemhorragic Colitis
  • HUS Kidney Failure (Renal Failure)
  • HUS pancreatitis
  • Central Nervous System (CNS)
  • HUS Seizures
  • HUS Coma
  • HUS Stroke
  • HUS Encephalopathy
  • HUS heart attack and heart failure
  • HUS Thrombocytopenia
  • E. coli Wrongful Death.

E. coli O103 Outbreaks

  • May 2019 Outbreak in KentuckyAn E. Coli O103 outbreak linked to fast food has sickened at least 19 in Kentucky.  The source is still being investigated.
  • Outbreak in a Nursery School – An E. coli O103 outbreak in a nursery school sickened at least 3 children. The source of the outbreak was not determined.1
  • Outbreak Linked to Sausage – During the spring of 2006, a national outbreak caused by Shiga toxin-producing Escherichia coli (STEC) O103:H25 was investigated in Norway. Genetic testing proved that isolates from one particular type of fermented sausage “morr sausage 1” were identical to the isolates from the outbreak victims. Samples of sheep meat that were linked epidemiologically to meat used for sausage production also contained isolates identical or closely related to patient strains.2

The amount of compensation for an E. coli 0103 victim is dependent on a number of factors, including the length of the hospital stay, the estimated time for recovery, complications related to the E. coli poisoning, estimated medical expenses into the future, and other factors.
