Accreditation programme testing requirements:
Blood test all cattle of two years old and older plus any breeding replacements aged 1-2 years old plus any non-homebred animals.
If clear then repeat herd test, as above, six to 12 months later.
To maintain accredited status:
Beef herds:
A statistical proportion of the breeding herd, of one year old and older, from each separately managed group (e.g. cow herd and followers) must be tested according to the figures in the table below. Breeding bulls must be tested.
For group sizes between these figures refer to next highest number e.g. for 80 cows sample 38.
As an example, for a 100 cow herd with 20 followers sample 38 cows and 19 followers.
Dairy herds:
Quarterly bulk milk testing is required.
In addition, a statistical proportion of the breeding herd, of one year old and older, from each separately managed group (e.g. cow herd and followers) must be tested according to the figures in the table above. Breeding bulls must be tested.
Monitored Free programme testing requirements:
Blood test all cattle of two years old and older plus any breeding replacements aged 1-2 years old plus any non-homebred animals.
After 6-12 months repeat the herd test of all cattle of two years old and older plus any breeding replacements aged 1-2 years old plus any non-homebred animals. Any animals previously identified as antibody positive can be excluded.
To maintain monitored free status:
Every 12 months repeat the herd test of all cattle of two years old and older plus any breeding replacements aged 1-2 years old. Any animals previously identified as antibody positive can be excluded.
Added animal testing:
Quarantine testing is optional for animals sourced direct from Leptospirosis accredited herds.
If cattle are from a non-Leptospirosis accredited herd (or from an accredited herd but purchased through a market) they must be placed in quarantine and tested after a minimum of 28 days (an earlier additional test is advisable either before purchase or early in quarantine period).
Cases where leptospirosis could be involved and testing is required to rule out disease:
Blood test at time of clinical signs and repeat 28 days later, whilst in isolation.
Any cow/heifer that aborts, has a stillborn calf or has evidence of resorption must be blood tested for antibodies to L.Hardjo. Advisable to submit abortion material for testing
