E. coli: A Common Yet Potentially Dangerous Bacteria

E. coli (Escherichia coli) is a type of bacteria that naturally lives in the intestines of humans and animals. Most strains are harmless, but some can cause serious foodborne illnesses.

Types of E. coli Infections

There are several types of E. coli infections, each with its own symptoms:

• Traveler's diarrhea: This is the most common type of E. coli infection and usually causes watery diarrhea, abdominal cramps, and fever.
• Urinary tract infections: E. coli can also cause urinary tract infections, leading to symptoms like burning during urination, frequent urination, and blood in the urine.
• Hemorrhagic colitis: A more severe type of E. coli infection that can cause bloody diarrhea, abdominal cramps, and vomiting.
• Hemolytic uremic syndrome (HUS): A serious complication that can occur after hemorrhagic colitis, leading to kidney failure, anemia, and low platelet count.

Causes of E. coli Infections

E. coli infections are typically caused by consuming contaminated food or water. Common sources include:

• Undercooked ground beef
• Contaminated produce
• Unpasteurized milk or juice
• Contaminated water

Prevention of E. coli Infections

To prevent E. coli infections:

• Cook meat thoroughly to an internal temperature of 75°C (167°F).
• Wash fruits and vegetables thoroughly.
• Consume only pasteurized milk and juice.
• Practice good hygiene, such as washing hands before and after preparing food.
