Minimize Wool Contamination
Contamination in the domestic wool clip gives every U.S. sheep producer a bad image. Contamination lowers the overall yield or useful quality of the wool clip. Common sources of wool contamination: dirt, vegetable matter, paint, polypropylene twine, colored fibers, and tags.
The shearing area must be kept clean with frequent sweeping to reduce risk of contaminating freshly shorn fleeces.
Use only new and approved wool packaging materials. Used bags and packs contaminate wool and cause identification problems.
Properly label all wool packages for: grower name, line or type of wool, individual bag number, and classer number (when applicable).
