Info

The statement provides: • A standardised animal health declaration form that would allow movement <strong>of</strong> sheep across state borders. • Information on <strong>the</strong> health status <strong>of</strong> o<strong>the</strong>r to minimise paperwork. • A tool for promoting and managing farm biosecurity. THE NATIONAL SHEEP HEALTH STATEMENT Industry organisations are very supportive <strong>of</strong> <strong>the</strong> move away from regulatory control and an increased emphasis on farm biosecurity. The Statement is a readily accessible tool to assist producers manage <strong>the</strong>ir risk <strong>of</strong> inadvertently sourcing sheep with OJD and also improves consistency and easier movement between states. There are five sections to <strong>the</strong> National Sheep Health Statement. Section 1 - Consignment information: Confirms <strong>the</strong> origin <strong>of</strong> <strong>the</strong> sheep and identification for traceability purposes. Section 2 - ABC score: A key feature <strong>of</strong> <strong>the</strong> National Sheep Health Statement is a producer’s declaration about <strong>the</strong> ABC score <strong>of</strong> <strong>the</strong> sheep in <strong>the</strong> consignment that indicates <strong>the</strong> level <strong>of</strong> risk <strong>of</strong> ovine Johne’s disease. Section 3 and Section 4 – Footrot and o<strong>the</strong>r health information: Endemic diseases which had previously required separate state based declaration forms. Section 5 – Declaration: Although using <strong>the</strong> Statement is voluntary in most states, it is a legal declaration under <strong>the</strong> stock diseases legislation and producers may be prosecuted for false declarations. The statement is not valid unless it is signed. How do producers work out <strong>the</strong>ir ABC score? Under <strong>the</strong> ABC Scheme, a sheep producer can claim credit points for his or her sheep under four Categories: A. Area and flock <strong>of</strong> origin - The known ovine Johne's disease status <strong>of</strong> <strong>the</strong> flock or <strong>the</strong> Prevalence Area from which <strong>the</strong> sheep originated. (Refer to Figure 1) B. Testing history, including negative flock tests for <strong>the</strong> Sheep Market Assurance Program, as well as negative abattoir monitoring. C. Vaccination history and whe<strong>the</strong>r <strong>the</strong> sheep are vaccinated <strong>the</strong>mselves, as well as whe<strong>the</strong>r <strong>the</strong>y come from a fully vaccinated flock and are <strong>the</strong> progeny <strong>of</strong> vaccinated sheep. The use <strong>of</strong> Gudair vaccine is encouraged in all prevalence areas. Vaccinated sheep are eligible for ABC points for vaccination if <strong>the</strong>y are identified by a standard NLIS (Sheep) ear tag incorporating a "V" identifier. D. Individual veterinary risk assessment for a consignment <strong>of</strong> sheep undertaken by an Approved Veterinarian. 219
Figure 1. Prevalence Areas, based on flock prevalence estimated from abattoir surveillance <strong>of</strong> slaughtered sheep, and <strong>the</strong>ir respective ABC credits. Sheep buyers are encouraged to obtain a declaration for any consignments <strong>the</strong>y are interested in buying and to learn what <strong>the</strong> ABC information on it means for <strong>the</strong>m. Buyers can <strong>the</strong>n determine <strong>the</strong> risk that those sheep present to <strong>the</strong>ir own flock, by relating <strong>the</strong> score <strong>of</strong> <strong>the</strong> sheep <strong>of</strong>fered for sale to <strong>the</strong>ir own flock score, and determining whe<strong>the</strong>r <strong>the</strong>y want to take that risk. The clear message is that <strong>the</strong> higher <strong>the</strong> ABC score <strong>of</strong> introduced sheep, <strong>the</strong> lower <strong>the</strong> risk and <strong>the</strong> greater confidence in protecting a flock’s ovine Johne's disease status. Extensive promotion <strong>of</strong> <strong>the</strong> use <strong>of</strong> <strong>the</strong> National Sheep Health Statement was undertaken prior to its launch in March 2008. A simple one page flier was developed with <strong>the</strong> message Don’t be fleeced when next you buy sheep and an easy to remember website was developed, www.ojd.com.au . The website is promoted as <strong>the</strong> central source <strong>of</strong> information, with links to and from each state website and key industry websites. In some states, animal health authorities have printed hard copies <strong>of</strong> <strong>the</strong> National Sheep Health Statement for distribution, but this is not encouraged as it <strong>of</strong>ten leads to producers using out <strong>of</strong> date statements. In <strong>the</strong> future, an E-form is planned for electronic lodgment and inclusion in presale catalogues. To reinforce <strong>the</strong> biosecurity component <strong>of</strong> this message <strong>the</strong> National Sheep Health Statement is also readily accessible from a high pr<strong>of</strong>ile website used to promote general farm biosecurity, www.farmbiosecurity.com.au. 220
