An outbreak of E. coli linked to McDonald’s Quarter Pounders has sickened at least 49 people in 10 states and has resulted in one death. The strain of E. coli involved, O157:H7, is one of the leading causes of foodborne illness in the U.S. E. coli is a type of bacteria that spreads through feces and can contaminate food, causing serious infection. Symptoms of E. coli infection include bloody diarrhea, severe stomach cramps, and vomiting.
While the bacteria can be found in contaminated food and water, it can also spread through contact with animals or infected individuals. The O157:H7 strain can lead to kidney complications and even death, particularly in vulnerable groups like young children and the elderly. Hemolytic uremic syndrome (HUS), a dangerous complication of E. coli infection, can cause damage to blood vessels, kidney injury, and other serious symptoms.
Preventing E. coli infection involves avoiding contaminated food, ensuring proper food preparation, and practicing good hygiene, such as thorough handwashing. Avoiding unpasteurized dairy and juices, and refraining from swimming in public pools or untreated water when experiencing diarrhea, can also help prevent the spread of the bacteria. Seeking medical attention promptly if infected is important to prevent complications.
Manufacturers have made efforts to reduce contamination in foods like ground beef, where E. coli is commonly found. Proper precautions and awareness of how E. coli spreads can help reduce the risk of infection, especially for vulnerable groups. Ultimately, understanding the dangers of E. coli and taking preventative measures can help protect against this harmful bacteria.
