What is STEC disease?

Shiga toxin-producing *Escherichia coli* (STEC) disease, also known as enterohemorrhagic *E. coli* (EHEC) infection, is a bacterial infection caused by certain strains of *E. coli* bacteria that produce Shiga toxins. These toxins can damage the lining of the intestines, leading to symptoms such as severe abdominal pain, bloody diarrhea, and fever. In severe cases, STEC disease can cause dehydration, electrolyte imbalances, and kidney failure.

STEC disease is transmitted through the ingestion of contaminated food or water. The most common sources of STEC infection include:

* Undercooked ground beef

* Unpasteurized milk or juice

* Contaminated fruits and vegetables

* Contact with animals, particularly cattle and sheep

STEC disease can affect people of all ages, but it is most common in children and the elderly. Symptoms typically develop within 3-4 days after exposure to the bacteria and can last for up to 10 days.

Treatment for STEC disease is supportive and includes:

* Fluids and electrolytes to prevent dehydration

* Antibiotics to kill the bacteria

* Pain relievers to reduce abdominal pain

* In severe cases, hospitalization may be necessary

STEC disease can be prevented by following these food safety tips:

* Cook ground beef thoroughly to an internal temperature of 160°F (71°C).

* Avoid unpasteurized milk or juice.

* Wash fruits and vegetables thoroughly before eating them.

* Avoid contact with animals, particularly cattle and sheep.

* Practice good hand hygiene, especially after using the bathroom and before eating.

If you experience symptoms of STEC disease, it is important to see a doctor immediately. Early diagnosis and treatment can help prevent serious complications.
