You can cut your risk by boning out the animals, rather than using a bandsaw to cut your steaks. The CWD lives in the bone marrow, not in the meat.
No. CWD is not connected to marrow.
Deer hunters should also know where CWD has been confirmed to ensure they have an animal tested following a successful hunt, and so that they follow all carcass transport regulations with respect to moving high-risk parts of harvested animals. High-risk parts include the brain, eyes, spleen, spinal cord and lymph glands, and multiple states restrict high-risk parts from entering from states that have confirmed CWD. Additional states prohibit hunters from bringing these parts into their state from any other state – regardless if that other state has confirmed CWD or not. Other than moving live animals, moving high-risk parts is the most likely way to move the disease and that’s why most states restrict or prohibit all movement of these parts.
