TN Health Dept Warns Against Consumption of Raw Milk

Press release from the Tennessee Department of Health; February 23, 2015:

NASHVILLE – In the quest for good health, some may believe “100 percent natural” is always best. That belief, however, doesn’t take into account some life-saving scientific advances which have made many products safer without any significant effect on their nutritional value.

“Pasteurized milk is a prime example of one food that is much safer thanks to a simple heating process that destroys harmful bacteria,” said Tennessee Department of Health Commissioner John Dreyzehner, MD, MPH. “It has been recognized by the Centers for Disease Control and Prevention as one of the ten great public health achievements of the 20th century.”

John Dunn, DVM, MPH, director of foodborne disease prevention services for the Tennessee Department of Health, said drinking unpasteurized milk, sometimes known as “raw” milk, is “a spin of the roulette wheel” in how it may affect a person’s health.

“It’s true many people grew up on farms and drank raw milk from their cows and goats with no ill effects,” Dunn said. “It’s also true others weren’t as lucky, swallowing bacteria-laden milk that did great harm. Pasteurization destroys dangerous microorganisms without substantially altering the taste or nutritive value of milk.

“In 2013, we had one outbreak of nine children in Tennessee becoming extremely ill after drinking raw milk, with five of those requiring hospitalization and three developing severe, life-threatening kidney problems,” Dunn continued. “In that outbreak, E. coli 0157 in their raw milk put those children’s lives at risk.”

Infants, young children, older people and those with weakened immune systems are at the greatest risks of serious health complications if they consume raw milk or products such as cheese, ice cream or yogurt made from raw milk. Women who are pregnant should also avoid unpasteurized milk or products containing raw milk. Of particular concern are children fed raw milk by parents who mistakenly believe they are making a healthier choice for their families.

Bacteria in raw milk can create a multitude of illnesses and damage to organs. Common symptoms of illness from drinking contaminated raw milk include vomiting, diarrhea, abdominal cramps, headaches, fever and body aches. While some may respond to medical treatment, others may suffer irreversible organ damage or death.

It is illegal to transport and sell raw milk across state lines and many states, including Tennessee, have laws which prohibit the sale of raw milk to consumers. Some skirt the law by purchasing a share of a cow for their personal consumption.

“Some sellers tout cleanliness of their dairy operation or the health of their livestock, but the simple fact is all raw milk contains bacteria that pasteurization would destroy,” Dunn said. “Your best choice for healthy, nutritious milk is the pasteurized kind you find in grocery stores and markets. Choosing raw milk instead can be one of the unhealthiest decisions you make for yourself or your family.”

Health Dept. Investigation Ties E.coli Ilnesses to Knoxville-Area Raw Milk Dairy

Press release from the Tennessee Department of Health; November 20, 2013:

NASHVILLE, Tenn. – The Tennessee Department of Health confirmed today the strain of E.coli that caused nine children to become ill after drinking raw milk obtained from McBee Dairy Farm near Knoxville has been matched to animal waste collected at the dairy. Five of the nine children required hospitalization and three developed a severe kidney problem known as hemolytic uremic syndrome.

The TDH investigation involved an on-site inspection of the farm, interviews of 88 households that purchased milk from the farm and laboratory analysis of samples and materials to compare bacterial strains. Officials from the Knox County Health Department have been involved in the investigation and patient outreach efforts.

“This outbreak points out, again, the serious risks associated with drinking unpasteurized or ‘raw’ milk,” said TDH Commissioner John Dreyzehner, MD, MPH. “While people with stronger immune systems may be able to overcome the bacteria found in raw milk, children, older people, pregnant women and those with health conditions can be seriously harmed by bacteria in non-pasteurized milk products and should not consume them.”

“Milk from the healthiest-appearing cows in the cleanest dairy operations can still contain deadly microorganisms,” said TDH State Epidemiologist Tim Jones, MD. “Pasteurization, which simply involves heating the milk, kills these microorganisms and leaves the healthy nutrients. Those who consume raw milk are playing Russian roulette with their health; the glass they drink today may not have deadly microorganisms, but the one they drink tomorrow may cause serious health problems or even death.”
