This document provides methods and materials for detecting misfolded polypeptides. For example, devices (e.g., feeding devices) designed to collect samples from one or more mammals (e.g., one or more cervids) are provided. In some cases, methods and materials that can be used to detect one or more prion diseases (e.g., chronic wasting disease (CWD)) in a population of mammals (e.g., a herd of cervids) based, at least in part, on the presence or absence of misfolded polypeptides in a sample from one or more mammals that was obtained from a feeding device are provided. |
