Also known as: Escherichia coli

Summary

Escherichia coli (E. coli) is a diverse group of bacteria commonly found in the intestines of humans and animals [14], [15], [26]. While most strains are harmless and aid in digestion, some are pathogenic and can cause severe foodborne illnesses [1], [14], [26].

What it is

E. coli is a Gram-negative, rod-shaped bacterium belonging to the genus Escherichia and the family Enterobacteriaceae [14], [23]. Pathogenic strains produce toxins that can cause gastrointestinal, urinary, or central nervous system diseases [15].

Common uses

Production of biopharmaceuticals such as insulin, hormones, enzymes, and vaccines [20]
Model organism in molecular biology research [19]

Public Perception

Anxiety level

High. Reports of outbreaks, severe illness, and potential long-term complications contribute to significant public anxiety [27], [28], [29].

Cultural claims

Recent E. coli outbreaks linked to fast food chains have caused public concern [27], [28], [29].
Some people claim raw milk, which can contain E. coli, has nutritional benefits, though experts say the risks outweigh the benefits [32].

Source sentiment

News and community discussions reflect concerns about E. coli outbreaks, particularly regarding food contamination and antibiotic resistance [27], [31].

History

Timeline

1919

Castellani and Chalmers proposed the name Escherichia coli [18].

1952

The Hershey-Chase experiment increased E. coli's use in molecular biology [35].

1982

E. coli O157:H7 was identified as the cause of bloody diarrhea from contaminated hamburger meat [44].

2011

A significant Shiga toxin-producing E. coli (STEC) outbreak occurred in Germany, causing numerous illnesses and deaths [24], [37], [38].

Origin

Theodor Escherich isolated E. coli from infant fecal samples while studying the effects of breastfeeding on gut health [17], [18], [35]. He initially named it Bacterium coli commune [18].

First appeared: 1885

Science

Key findings

STEC strains produce Shiga toxins, leading to bloody diarrhea and hemolytic uremic syndrome (HUS) [1], [14], [23].
Source attribution analysis links STEC infections to bovine meat, dairy products, water, and fresh produce [1].
Antibiotic resistance is an increasing concern in E. coli infections [5], [6], [31].

Studies

Pathogenicity assessment of Shiga toxin‐producing Escherichia coli (STEC) and the public health risk posed by contamination of food with STEC

All STEC strains are pathogenic in humans and capable of causing diarrhea, with some subtypes associated with severe illness such as bloody diarrhea and HUS [1].

A systematic review and meta-analysis of the global epidemiology of carbapenem-resistant Escherichia coli

Carbapenem-resistant E. coli poses a significant global health threat due to its resistance to multiple antibiotics [5].

The Global Prevalence of Antibiotic Resistance and Shiga Toxin-Producing Escherichia coli in Chickens: A Systematic Review and Meta-Analysis (2011-2024)

Shiga toxin-producing E. coli (STEC) are important foodborne pathogens that cause serious public health consequences worldwide and exhibit resistance to common antibiotics [7].

Safety status

Generally, E. coli is a normal part of the gut flora, but certain strains are pathogenic and can cause illness [15], [26].

Nuance

The severity of E. coli infections varies greatly depending on the strain, the individual's health, and the presence of complications like HUS [1], [26], [44].

Alternatives

Pasteurized milk and juice
Pasteurization kills harmful bacteria, including E. coli [32].
Where to find: Grocery stores

Thoroughly cooked meats
Cooking meat to the recommended internal temperature kills E. coli [23], [26].

Avoidance tips

Wash hands thoroughly with soap and water before and after handling food [25], [28].
Wash fruits and vegetables thoroughly before consumption [25], [26].
Avoid cross-contamination by using separate cutting boards and utensils for raw meats and produce [25].
Use water from a safe source [26], [30].
