Escherichia coli O157:H7 is a serotype of the bacterial species Escherichia coli and is one of the Shiga-like toxin–producing types of E. coli. It is a cause of disease , typically foodborne illness , through consumption of contaminated and raw food, including raw milk and undercooked ground beef .
[2] [failed verification] The ones that do are collectively known as enterohemorrhagic E. coli (EHEC) and are major causes of foodborne illness. When infecting the large intestine of humans, they often cause gastroenteritis , enterocolitis , and bloody diarrhea (hence the name "enterohemorrhagic") and sometimes cause a severe complication ...
But there are different strains of E. coli, and some can be potentially dangerous. This recall involves one of those types. Referred to as E. coli O157:H7 or Shiga toxin-producing E. coli (STEC ...
In June 2009, Nestlé Toll House cookie dough was linked to an outbreak of E. coli O157:H7 in the United States, which sickened 70 people in 30 states. [66] In May 2011 an epidemic of bloody diarrhea caused by E. coli O104:H4-contaminated fenugreek seeds hit Germany. Tracing the epidemic revealed more than 3,800 cases, with HUS developing in ...
The U.S. Centers for Disease Control and Prevention recommend that "all stools submitted for routine testing from patients with acute community-acquired diarrhea (regardless of patient age, season of the year, or presence or absence of blood in the stool) be simultaneously cultured for E. coli O157:H7 (O157 STEC) and tested with an assay that ...
Some strains of Escherichia coli cause bloody diarrhea. The typical culprits are enterohemorrhagic Escherichia coli, of which O157:H7 is the best known. These types of E. coli also make Shiga toxin. [23]
Shiga-like toxin (SLT) is a historical term for similar or identical toxins produced by Escherichia coli. [3] The most common sources for Shiga toxin are the bacteria S. dysenteriae and some serotypes of Escherichia coli (shigatoxigenic or STEC), which include serotypes O157:H7, and O104:H4. [4] [5]
The E. coli O157:H7 strain that has caused the death of one person is said to cause "very serious disease", especially for the elderly, children and people who are immunocompromised.
