Could Deer Spin feeders be the leading Cause Of CWD in dear species?

Could Gravity Spin feeders that congregate deer in large Numbers be helping to Spread CWD? Are there any good papers on this subject has any research been done.
Seems like to me a high amount of shed proteins might be found around these devices in fall and winter.
Where can I find information?
