What if Merino sheep are placed in yards previously used for exotic breeds prior to shearing?
There is a risk of contamination of the Merino wool in these circumstances. The AWEX Code of Practice states that the shearing shed must be thoroughly cleaned between the shearing of wool from pigmented and/or medullated sheep and the shearing of Merino wool. Sheep yards also require the same level of attention in terms of cleanliness, such that wool from pigmented and/or medullated sheep should be picked up and disposed of prior to Merinos entering the yards.
