Abstract
Grass seed contamination of sheep carcasses and skins results in significant losses across the Australian lamb and mutton value chains. Seven grass species found across Victoria (VIC) and New South Wales (NSW) are known to significantly impact carcass quality, with barley grass and brome grass as key perpetrators. To evaluate current trends associated with carcass weed seed contamination, extensive abattoir datasets (2009–2014) provided by Animal Health Australia (AHA) were analysed by state and biogeographic region. Significant differences in regional infestation were noted, with reduced contamination observed in Tasmania (TAS) and VIC in contrast to other states. No significant differences were observed in contamination between NSW and Queensland (QLD). Highest contamination occurred throughout the mixed cropping and pastoral zones, with notable events also in the high rainfall zone. Sex and age of animal were identified to have impacted seed contamination. These findings have implications for integrated weed management (IWM) strategies for weed species of importance to the livestock production chain.

| Other | In 2016, the Council of Australasian Weed Societies (CAWS), along with local hosts the Weeds Society of Western Australia, are celebrating the 20th Australasian Weeds Conference. The biennial conference is being held at the Pan Pacific in Perth, Western Australia which has traditionally been one of the highest attended AWC's, and over 300 delegates are expected from across Australasia. Delegates will come together to meet-up with peers, engage with industry sponsors, and to listen and participate in presentations and field trips on a variety of topics including: Herbicide Resistance Weeds of National Significance Agricultural weeds Environmental weeds Biological control of weeds Modelling and new technologies to manage weeds Legislation, regulation and policy to manage weed |
