Naonal Sheep Health Declaraon - Explanatory Notes
1: Biosecurity Plan: Agreed and documented acons and acvies to prevent the
incursion of animal disease(s) into a
ock or onto a property. It may outline measures
including (but not limited to) condions on sheep movements into an area, vaccine
policy and response to disease detecon. These plans can be at a property or regional
level and can cover a range of diseases. The Naonal Farm Biosecurity Reference
Manual for Grazing Livestock Producon and Regional Biosecurity Plan guidelines can be
used to develop plans.
2: Declared noxious weeds: Declared noxious weeds can be referred to as declared
weeds or plants, noxious weeds or Weeds of National Significance. Details regarding
your relevant state information and legislation can be found at:
http://www.farmbiosecurity.com.au/essentials-toolkit/ferals-weeds/#weeds
3: Footrot: Virulent footrot is defined differently in each state. For information on
interstate movements of sheep, producers should visit the relevant state department
website or contact animal health staff from that department.
4: Approved Vaccinate: A sheep that is identified by an NLIS (sheep) ‘V’ tag and is:
• vaccinated with an approved OJD vaccine by 16 weeks of age, or
• vaccinated with an approved OJD vaccine aer 16 weeks of age, when the ock:
• was in the SheepMAP, or
• had undertaken a negave Faecal 350 test in the two (2) years preceding the
vaccinaon, or
• had a Negave Abaoir 500 status at the me of vaccinaon.
5: SheepMAP: An audited quality assurance program incorporang a property
biosecurity plan, animal health risk assessment, tesng, and movement controls that
provide a source of low risk animals. (Note: level of tesng varies depending on status)
6: NLIS ‘T’ tag (terminal) lamb: A lamb which is to be slaughtered before it cuts its
rst permanent teeth and is idened by an NLIS (sheep) ‘T’ tag. The ‘T’ tag may be a
requirement for trading into some areas.
7: Answering this queson is important for movements of sheep into or within
Regional Biosecurity Plan areas and to other low risk properes. It is less important
for movements which rely on vaccinaon to manage Johne’s disease (JD, previously
referred to as OJD) impacts. Flocks which are not known or suspected of being infected
should answer ‘No’.
Infected Flocks: A ock which is infected with JD, and there is evidence of or likely potenal
for transmission of infecon within the ock, and the ock has not met the requirements
for resoluon of infecon in accordance with the current Naonal OJD Standard Denions,
Rules and Guidelines (SDR&Gs).
Suspected of being infected: A ock is suspected of being infected with JD if the owner has
reasonable grounds to believe that the ock has been exposed to JD infecon or that JD
may exist in the ock, based on:
• trace back or trace forward contact with an infected ock
• contact with JD contaminated land or facilies
• a posive JD screening test, e.g. abaoir monitoring or blood (ELISA) test
• is a neighbour of an infected ock unless there is an eecve biosecurity barrier
• clinical signs of JD, or
• advice from the relevant state agricultural department.
AND the ock has not met the requirements for resoluon of suspicion in accordance with
the SDR&Gs.
8: Faecal 350: A test of 350 representave sheep over 2 years of age (or all sheep over 2
years of age in smaller ocks) by Pooled Faecal Culture (PFC) or High Throughput Johne’s
(HT-J) PCR in pools of up to 50 sheep. The sheep must have been on the property for at least
2 years.
Abaoir 500: At least 500 sheep, over 2 years of age, have been submied to an abaoir
in the past 24 months, in 1 or more lots, have been examined and all found negave for JD.
The sheep must have been on the property for at least 2 years.
Abaoir 150: At least 150 sheep, over 2 years of age, have been submied to an abaoir
in the past 12 months, in 1 or more lots, have been examined and all found negave for JD.
The sheep must have been on the property for at least 2 years.
9: Other: Post mortem examinaon by a SheepMAP vet with no indicaon of JD, or other
negave test.
10: Other: This could include sheep sourced from historical Low Prevalence Areas (LPA).
11: Declaraon: Signing this declaraon has legal signicance. Regulatory authories may
take legal acon, and purchasers may seek damages for any informaon that is incorrect.
Before signing you must be sased you understand all elements of the document, and these
