I went to this web site(CWD-INFO.ORG) and asked a question(s) related to cwd and food plots and if any studies were in progress. Here is his response:
Scott,
Thanks for sending your inquiry into the CWD Alliance! Your question is a good one and is also one that has sparked debate among biologists and hunters for many years. To answer plainly, any situation, whether created by natural or artificial means, that causes wild animals to congregate at or regularly revisit a specific location, has the potential to cause an increase in animal to animal contact and environmental contamination that can potentially spread disease and/or parasites. CWD is only one of many diseases that can be spread and propagated through the congregation of animals. There is no doubt that if feed plots were being used in an area where CWD was present in wild populations, the risk of spreading the disease at that site would increase. Based on studies from the University of Michigan, risk of CWD transmission at these sites may be even higher than most diseases since the prions likely responsible for transmitting the disease persist in the soil for several years. These finding have been anecdotally verified at the Colorado Division of Wildlife Research Facility where CWD was first identified. Over the years, repeated attempts at sterilizing the facility and its grounds have failed. Every cervid that has been housed at the facility has contacted the disease seemingly from the environment (likely soil).
To my knowledge, no one is presently conducting a study specifically on feed plots and their potential role in spreading CWD. While such a study would be interesting, the ongoing environmental contamination studies of CWD will likely yield the results needed to help wildlife managers regulate the issues you have identified.
I hope I answered your questions. If not, please don't hesitate to contact me so we can visit further.
