However, it is recommended no one consume a walleye they suspect is infected. According to CPW, the disease typically occurs in the Midwest, particularly in North and South Dakota, Minnesota, Wisconsin and Nebraska.
It has spread to the West, including in Utah, Idaho, Wyoming and now Colorado."It’s not a shock that it has reached Colorado since it occurs in so many neighboring states, but it is unfortunate," said Carrie Tucker, CPW aquatic biologist in Pueblo. "We don’t expect it to have a big impact because it typically only shows up in a small number of older walleye."CPW alerts anglers of rare "Sandy Flesh disease" has been found in a walleye taken at Lake Pueblo State Park.
The agency urges people to avoid consuming infected fish and to contact CPW. (Colorado Parks and Wildlife)The disease has existed for decades and typically impacts a few fish in various states, wildlife officials said.
