Tennessee county sees increase in E. coli infections from raw milk
The Hamilton County, Tennessee Health Department has identified an unexpected increase in E. coli cases. coli producing Shiga toxins associated with the consumption of raw, unpasteurized milk.
The Health Ministry’s notice did not include the names of the dairies involved.
“Raw milk may contain harmful bacteria that can cause serious illness or death, especially in young children, the elderly, pregnant people, and people with weakened immune systems,” according to the health ministry alert.
“If you or your child have recently consumed raw milk and experience diarrhea, fever, stomach cramps or vomiting, consult your doctor immediately.”
The Department of Health’s investigation is ongoing and may be aided by consumer reports of illnesses developing after consuming raw milk.
Children under five are particularly susceptible to infections caused by raw milk.
State and federal health officials regularly warn about the dangers of raw milk. More than 95 percent of dairy-related foodborne illness outbreaks involve raw milk.
Pasteurization heats milk to 161 degrees for 15 seconds to kill harmful bacteria and viruses such as E. coli, Salmonella, Listeria, Campylobacter and Hepatitis A.
About E. coli infections
Anyone who has consumed raw milk and developed symptoms of E. coli infection should seek medical attention and inform their doctor of their possible exposure to the bacteria. Specific tests are needed to diagnose infections, which can mimic other illnesses.
Symptoms of E. coli infections vary from person to person, but often include severe stomach cramps and often bloody diarrhea. Some patients may also have a fever. Most patients recover within five to seven days. Others may develop serious or life-threatening symptoms and complications, according to the Centers for Disease Control and Prevention (CDC).
About 5 to 10 percent of people diagnosed with E. coli infection develop a life-threatening kidney failure complication, known as hemolytic uremic syndrome (HUS). Symptoms of HUS include fever, abdominal pain, feeling very tired, decreased frequency of urination, small unexplained bruising or bleeding, and paleness.
Many people with HUS recover within a few weeks, but some suffer permanent injury or even death. This disease can occur in people of any age, but is most common in children under five years old due to their immature immune systems, in older people due to their deteriorating immune systems, and in people with weakened immune systems, such as cancer patients.
People experiencing symptoms of HUS should seek emergency medical attention immediately. People with HUS will likely be hospitalized because the condition can lead to other serious and long-lasting problems such as hypertension, chronic kidney disease, brain damage, and neurological problems.
