margin-left:60px;(0,0,0);' ', 'Segoe UI', 'Lucida Grande', ;In response to The Star’s series on deer farming, Don Davis, in his June 30 op-ed, dismissed Ryan Sabalow’s reporting as a one-sided attack on the family farm. Davis’ arguments, clearly in support of the captive deer industry, ignore broad policy questions, and attempt to minimize the risk this industry poses to our wildlife resources and, potentially, to human health.
margin-left:60px;(0,0,0);' ', 'Segoe UI', 'Lucida Grande', ;Most business types involve a spectrum of actors: some exemplary, most hardworking and honest, and (unfortunately) a few scoundrels. The recent spate of Lacey Act convictions, including some in Davis’ home state of Texas, for illegally transporting deer across state lines, underscores that point. With a disease like chronic wasting disease, a single reckless incident may move disease and cause irreparable harm to the public’s wildlife resources.
margin-left:60px;(0,0,0);' ', 'Segoe UI', 'Lucida Grande', ;Sabalow concluded that farmed deer, because of inadequate testing and frequent movement between facilities and states, constitute a risk to wild deer. Davis argues against this route of disease transmission and suggests, “If anything, it is more accurate to say the opposite� (implying that wild deer, a public resource, constitute a risk to privately-held deer farmers). Canadian epidemiologists have concluded that movement between game farms is the root cause of CWD spread in Canada (with the original source being a South Dakota game farm), and that the disease subsequently spilled over into wild deer. CWD prevalence in wild deer in parts of Saskatchewan is nearly 50 percent. According to Davis’ theory, the opposite occurs in the U.S.?
margin-left:60px;(0,0,0);' ', 'Segoe UI', 'Lucida Grande', ;Davis attempts to minimize potential disease impacts by stating that “CWD occurs in only about four in 1,000 deer.� True, but a trained epidemiologist should recognize that national averages provide a rather incomplete picture for infectious diseases, which tend to cluster on the landscape.
margin-left:60px;(0,0,0);' ', 'Segoe UI', 'Lucida Grande', ;Davis continues by stating that CWD prevalence is lower in game farms than in wild deer. Again, a misleading argument, because game farms have historically been quickly depopulated (at taxpayer expense and with taxpayer-provided indemnification) after the initial detection of disease (before prevalence can rise).
margin-left:60px;(0,0,0);' ', 'Segoe UI', 'Lucida Grande', ;Davis concludes that CWD “does not appear to be a threat to humans.� John Gummer, former British environment secretary, famously made the same statement about mad cow disease in a “made-for-media� event where he fed a hamburger to his daughter to demonstrate the safety of British beef. We know how that turned out. One thing the study of diseases has shown us is to “never say never.�
