| A voluntary dark and medullated fibre risk (DMFR) scheme was introduced for Merino fleece and piece wool in July 2004 initiated by the Australian Council of Wool Exporters. It provides a rating of the risk of dark and medullated fibre contamination recorded on Australian Wool Testing Authority (AWTA) test certificates and in sale catalogues. This program is promoted by some brokers and it is expected that market forces will show premiums for the declared clean wools.
The DMFR Scheme allows:
- Wool producers to promote their clips as white and uncontaminated
- Wool buyers and processors to minimise the risk of buying contaminated wool
- Better analysis of price differences for wools with various contamination risks
- Protection and advancement of Australia’s woolclip reputation as white and non-contaminated. Merino sheep producers have the option of supplying DMFR information for all, some, or none of their fleece and piece lines.
Non declared wools will be branded “ND” in the Auction catalogue, indicating to buyers that there is some risk associated with these wools.
The diagram (below) shows how the DMFR rating for your wool is determined:
