The public health risks of cervid production in the United States of America.
Cervid species represent a growing livestock enterprise in the United States of America (USA). The zoonotic threat of bovine tuberculosis (Mycobacterium bovis) is the only significant public health risk posed by this alternative livestock industry. This paper examines the potential sources of tuberculosis exposure as related to public health and compares and contrasts the status of tuberculosis in Cervidae with the situation in the cattle industry in the USA. Based on the existing prevalence of the disease and the limited potential of human exposure to infected meat or meat products, bovine tuberculosis in Cervidae poses a minimal threat to public health. The only significant public health concern is exposure to infected free-ranging cervids of hunters who field-dress carcasses and may unknowingly incise tuberculous lesions. This risk is mitigated only by the small size of the cervid population at risk when compared to the general population of cervids hunted yearly.
