Fallows and diseases

Fallows do not get nor do they carry Chronic Wasting Disease

CWD affects Whitetail Deer as well as Elk and is being spread by wild populations in the north western part of Virginia. A study by the United States Department of Agriculture indicates a low probability for oral transmission of CWD to cattle as well as Fallow deer.
Due to their genetic makeup Fallows can not cross breed with Whitetails and they are not affected by CWD nor are they carriers.
Species that have been affected with CWD include elk, mule deer, white-tailed deer, black-tailed deer, and moose. Other ruminant species, including wild ruminants and domestic cattle, sheep, and goats, have been housed in wildlife facilities in direct or indirect contact with CWD-affected deer and elk with no evidence of disease transmission. There is ongoing research to further explore the possibility of transmission of CWD to other species
Researchers say CWD occurs naturally in mule deer, white-tailed deer, and elk, which are members of the deer family, as are moose, reindeer, and caribou. Reindeer and caribou belong to the same species, Rangifer tarandus. No cases of CWD in reindeer or caribou have been reported.
CWD was first reported in Colorado 1967 and has been heading East ever since, reported in Virginia in 2009 and Maryland in 2010
The species known to be susceptible to CWD are Rocky Mountain Elk (Cervus elaphus), Mule deer (Odocoileus hemionus) and Black-Tailed Deer (Odocoileus hemionus) and White-Tailed Deer (Odocoileus virginianus). Because Red Deer (Cervus elaphus) are genetically very similar to Rocky Mountain Elk, it is likely that they are also susceptible to CWD.

Tuberculosis and deer

Tuberculosis (TB) is a serious disease caused when bacteria attack the respiratory system. There are three types of TB - human, avian, and bovine. Human TB is rarely transmitted to non-humans, avian TB is typically restricted to birds (pigs and occasionally other animals have been found to be susceptible), and bovine TB - or cattle TB - is the most infectious, capable of infecting most mammals. Bovine TB is caused by the bacterium Mycobacterium bovis (M. bovis) which is part of the Mycobacterium tuberculosis complex.

Cattle are almost certainly the primary source of Bovine Tuberculosis in wildlife. The Government needs to work with stakeholders to formulate a bTB control strategy that effectively controls the disease in cattle while making the best use of limited resources. Although bovine TB was once relatively common in cattle in the U.S., it has historically been a very rare disease in wild deer.

You may be pointed to the State of Michigan and the Bovine-TB infected Whitetails these are Wild Deer who contracted the disease from mingling with cattle if they were farmed deer kept in a paddock the spread of disease could have been controlled


Deer and Lyme disease
Ticks are only dangerous if they are infected, and deer play no role in infecting ticks. Ticks become infected with the Lyme disease bacterium by feeding on small mammals such as white-footed mice, chipmunks, and shrews.
Deer show no symptoms of lyme disease. Deer may carry small numbers of the spirochete that causes Lyme disease but they are dead-end hosts for the bacterium. Deer cannot infect another animal directly and no deer hunter has acquired the disease from dressing out a deer. Infected ticks that drop from deer present little risk to humans or other animals since the ticks are now at the end of their life cycle and will not feed again. There is no evidence that humans can become infected by eating venison from an infected deer. Adult black-legged ticks ( Deer Ticks) feed on raccoons, skunks, opossums, and other medium-sized mammals. When deer are scarce, ticks don’t necessarily become scarce, because they have alternative hosts . Wild Deer spred ticks by roaming Farmed Deer do not roam
Brucellosis
Brucellosis is a highly contagious disease of many animals and is caused by bacteria of the genus Brucella. Brucella abortus most commonly affects cattle; B. Suis is most common in swine; B. melitensis is most common in goats. Although infections may occur in other species, including man, such situations are rare. B. abortus is the species of most concern to wildlife workers.
Brucellosis has been reported throughout the world since its discovery in the latter part of the nineteenth century, and has long been considered an important disease in man, cattle, goats and swine. It has been found in bison, elk, moose, Dall sheep, caribou and several species of deer. It has been diagnosed in dogs, foxes, hares, mice, rats, ticks and fleas. The disease is relatively rare in deer in the U.S., slightly more significant in elk, bison and moose. In many areas of the U.S., white-tailed deer (Odocoileus virginianus) are known to associate with cattle. Yet, of over 17,000 white-tailed and mule deer (O. hemionus) tested, only 20 white-tailed deer reacted positively to Brucella tests. No reactors were found in over 1,200 white-tailed deer in Michigan. Also, of 435 miscellaneous wild birds and mammals representing 23 species from southern Michigan, all were negative. It is generally felt that Brucella organisms are not readily transmissible from their preferential host to dissimilar hosts, and that no serious or threatening reservoir of infection exists presently in wild animals in the U.S.
It is generally agreed that, rather than wildlife posing a threat to domestic species, the reverse is true: wildlife are more likely to acquire the disease from domestic species. Regardless, the incidence of brucellosis in wildlife is extremely low, and is of little significance in the population dynamics of any wild species.
