Escherichia coli O157:H7 is a strain of E. coli that produces Shiga toxin, causing severe intestinal infection in humans [3], [16]. It is a foodborne pathogen that can lead to hemorrhagic colitis and hemolytic uremic syndrome (HUS) [3], [15].
High. E. coli O157:H7 is associated with severe illness, potential long-term health outcomes, and recalls, leading to public health concerns [3], [7], [13], [25].
Consumption of undercooked beef, unpasteurized dairy products, and contaminated produce are common routes of exposure [3].
E. coli O157:H7 was first identified as a cause of illness during an outbreak of severe diarrhea linked to undercooked hamburgers in the United States [3], [15], [31], [34].
Outbreak of E. coli O157 from Jack in the Box hamburgers leads to new regulations [26].
Contamination of Walkerton, Ontario water supply by E. coli O157:H7 results in several deaths [32].
A large food-borne outbreak in Germany was caused by a novel strain of enteroaggregative E. coli O104:H4 transduced by a Stx2a-converting phage [17].
A UK-wide outbreak of Shiga toxin-producing E. coli O157 occurred, with 259 confirmed cases [21].
McDonald's E. coli crisis reveals challenges in controlling vegetable contamination [22].
Escherichia coli O157:H7: Epidemiology, Pathogenesis, and Methods for Detection in Food
E. coli O157:H7 is an important human pathogen transmitted primarily through food, with cattle as a major reservoir. Adhesion to intestinal epithelial cells and verotoxins are important virulence factors [1].
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 at least diarrhea, and all STEC subtypes may be associated with severe illness. Bovine meat, dairy products, tap water, and vegetables/fruits are main sources of STEC infections [2].
Chronic sequelae of E. coli O157: systematic review and meta-analysis of the proportion of E. coli O157 cases that develop chronic sequelae
E. coli O157 infections can lead to chronic sequelae such as hemolytic uremic syndrome (HUS) [7].
Risk factors for sporadic infections caused by Shiga toxin-producing Escherichia coli: a systematic review and meta-analysis
Risk factors for STEC infection include foreign travel, contact with ill people or farm animals, consumption of beef, processed meat, raw dairy, and composite foods [8].
Shiga Toxin (Verotoxin)-producing Escherichia coli and Foodborne Disease: A Review
STEC infections can range from mild discomfort to bloody diarrhea, HUS, ESRD, and death, making it a serious public health burden [14].
Thoroughly Cooked Meat
Properly cooking meat to an internal temperature of 160°F (71°C) kills E. coli O157:H7 [38], [42].
Pasteurized Dairy and Juices
Consuming only pasteurized milk, milk products, juices, and ciders reduces the risk of E. coli O157:H7 infection [42].
Hydroponic Lettuce
Hydroponic lettuces are less likely to be contaminated by bacteria from animal droppings [43].
Wash raw fruits and vegetables thoroughly under running water [3], [42], [47].
Avoid cross-contamination by keeping raw meat separate from ready-to-eat foods [42], [44].
Practice frequent hand washing, especially after contact with animals or raw foods [25], [42], [47].
Use separate cutting boards and utensils for raw meat and produce [44].
Refrigerate perishable foods promptly to prevent bacterial growth [43], [44].
