Raw Milk From Rabid
Cow - 45 Begin
Rabies Treatment

The Rogers County Health Department held a special clinic Saturday [31 Dec 2005] to begin treating people identified as at risk for contracting rabies after drinking raw milk from a rabid cow.
 
Oklahoma State Department of Health officials announced last week that people who drank raw, un-pasteurized milk or cream sold by Swan Bros. Dairy in Claremore from 4-19 Dec 2005 may have been exposed.
 
So far, 45 people have begun receiving a regimen of rabies vaccinations, officials said.
 
A Claremore resident and father took his 2 children to the Rogers County Health Department before going to their grandmother's house.
 
A 15-year-old victim said she did not like having to spend part of her Christmas Eve receiving shots, but that the injection was not too painful. Her brother, a 13-year-old, said he was a little nervous before receiving the shot, but said the experience was not as bad as he thought it would be. The Health Department is normally not open, but 17 employees worked at Saturday's clinic.
 
"The public health call goes out, and we respond," said Rick Garner, a registered nurse for the department's communicable disease division. "We are here to make sure the public is safe." By holding the Saturday [31 Dec 2005] clinic, the Health Department can help the public receive the injections with the "least amount of stress and inconvenience possible," Garner said.
 
Most healthy people who drank the milk or cream are not at risk for contracting rabies, Garner said. However, people with certain medical conditions, including suppressed immune systems or oral sores, should call the Health Department to determine whether post-exposure treatment is needed.
 
Families flowed into the Rogers County Health Department on Saturday [31 Dec 2005] morning, and people continually called. Many appeared concerned that recent dental work coupled with raw milk consumption put them at risk for contracting the virus. Garner said each person who contacts the department is evaluated either in person or via telephone to determine his or her level of risk. The preventive shots range from USD 2500 - 4000 for the course of treatment. The post exposure injections can cause side effects, including redness, fever and fatigue, so shots are given only to those who are at high risk for rabies.
 
The Health Department is working with Swan Bros. Dairy and its insurance company to explore the possibility of paying the bill for the vaccinations, said Dr. Mike Crutcher, state health commissioner.
 
One cow in the dairy's herd recently died from rabies, the state Health Department confirmed on 20 Dec 2005. The dairy sells raw milk at its Claremore farm, which began operating in 1923. Garner said dairy owner Harley Swan Jr. has been very cooperative with the health department's investigation. "The Swans have been very good people, and they are trying to do the right thing," he said.
 
Since the Health Department issued a public health alert Wednesday [28 Dec 2005], more than 500 people have called the state's hot line and the Rogers County Health Department for more information. Officials said the call volume dramatically decreased Saturday [31 Dec 2005], but not everyone who needs to be treated has started their regimen of shots. Some plan to wait until after Christmas to begin treatment.
 
Humans are usually exposed to rabies, a potentially fatal viral infection that attacks the nervous system, when they are bitten by infected animals such as bats, said Kim Rayno, an epidemiologist for the Health Department. There have been no documented cases of human rabies because of consumption of milk from a rabid animal, Rayno said. However, because there is a chance for transmission, the Health Department decided to issue a public health alert.
 
The milk that may have been infected was not pasteurized. Pasteurization, a heating-and-cooling treatment that kills organisms in the milk, would have killed the rabies virus, Garner said. Un-pasteurized milk can also contain _E. coli_ and salmonella.
 
Milk sold at commercial stores and restaurants must be pasteurized, and none of the possibly infected milk was used to make Swan Bros. cheese, which is shipped across the country.
 
Swan said Friday [30 Dec 2005] that the dairy produced nearly 5000 gallons of milk from 4-19 Dec 2005. The infected cow's milk was mixed with the milk of up to 70 other healthy cows, therefore diluting any infected milk that could have been present. Additional tests are being run to determine whether there was any of the virus in the milk. Before this incident, Swan said, he did not vaccinate his herd for rabies, but he will start doing so this week.

Callers may page an epidemiologist during the holiday weekend. Health Department officials said they will have staff on call to answer messages left on the hotline.

62 Now Treated For Rabies After
Drinking Raw Milk From Rabid Cow

More people are receiving treatment after possibly contracting rabies from drinking the raw milk of a rabid cow, according to Oklahoma State Department of Health officials.
 
As of Tuesday [27 Dec 2005], 62 people had been treated, up from 45 last week, officials said.
 
The Atlanta-based Centers for Disease Control and Prevention tested the brain matter from the dead cow and concluded, as the state did, that the animal had rabies. Initial state tests of the cow's udder were negative for rabies, but results from CDC udder tests will not be available until next week [1st week January 2006], said Dr. Brett Cauthen, the state epidemiologist.
 
Health Department officials announced last week [4th week December 2005] that people who drank raw, un-pasteurized milk or cream sold by Swan Bros. Dairy in Claremore from 4-19 Dec 2005 may have been exposed to the virus.
 
The Rogers County Health Department held special clinics Saturday and Monday [24 and 26 Dec 2005] to provide a preventive or prophylaxis rabies regimen.
 
Cauthen said calls to the state's information hotline have decreased, but the department is still receiving some inquiries each day from concerned milk drinkers. He said officials suspect the cow was infected when it was bitten by a rabid skunk, and additional laboratory tests will confirm what type of animal infected the dairy cow.
 
The Swan Bros. operators did not vaccinate their dairy herd, which would have prevented the infection, but they plan to vaccinate their animals this week.
 
The milk that may have been infected was not pasteurized. Pasteurization, a heating-and-cooling treatment that kills organisms in the milk, would have killed the rabies virus. Milk sold at commercial stores and restaurants must be pasteurized, and none of the possibly infected milk was used to make Swan Bros. cheese, which is shipped across the country.
 
For information on potential rabies exposure from un-pasteurized Swan Bros. milk, call the State Health Department hotline at (405) 271-0980.

Rabies, a _Lyssavirus_, normally affects the neurological tissue. However, the virus is most often transmitted through saliva or contact with oral or gastric mucosa (1). Additionally, rabies virus also has been detected in the kidney, prostate, pancreas, and other tissues and body fluids (2). In naturally occurring cases, the proven vehicle for transmission is saliva and neural tissue.
 
Anecdotal reports exist of rabies transmission by ingestion of milk by a nursing lamb from its mother (1). However, in all of these reports, a bite or mucous membrane exposure could not be ruled out. Transmission of rabies virus in un-pasteurized milk is a theoretical possibility.
 
The risk of contracting rabies through milk could be better defined if samples of milk and mammary tissue were collected from rabid livestock and assayed for the presence, viability, and infectivity of rabies virus. Regardless of the amount of viable rabies virus that may be shed in cow's milk, the theoretical risk for transmission of rabies from this route can be eliminated if all dairy products are pasteurized before consumption.
 
Another source of exposure have included neural tissues, such as a transplanted corneas, and laboratory aerosols. Recently, the 1st U.S. instance of human rabies transmission via solid organ transplantation was documented in 3 recipients of a donor unsuspected of having rabies; transmission via organ transplantation has also been documented in other countries.
 
The development of rabies generally takes 10 to 90 days when the virus is transmitted through a bite.
