Part C: Options to continue Farming Activities on Infected Premises

15. Determination of Clinical Resolution on a Property (Day Zero)

 

15.1 The date of clinical resolution (Day Zero) for the premises will be proposed by the supervising state veterinarian in writing after conducting clinical examination on all cloven-hoofed animals on the property.

 

15.2 Day 0 (zero) is calculated as follows:

 

15.2.1 If the outbreak presented with clinical signs of FMD in non-vaccinated livestock:
(a) Once there are no obvious fresh signs of clinical disease, the state veterinarian must be informed and arrangements made for clinical examination, by an authorised veterinarian including mouthing, within 5 days,
(b) The preliminary clinical end point will be when there has been an absence of fresh clinical signs of disease, as determined by the authorised veterinarian. If no fresh signs of clinical disease are observed by the authorised veterinarian, that date must be noted.
(c) The clinical examination by the authorised veterinarian must be repeated after 14 days to confirm absence of fresh clinical signs. If there is no evidence of clinical signs, the date of preliminary clinical end point will be taken as Day Zero

 

OR

 

15.2.2 If animals were vaccinated, the date of first vaccination of the last animal on the property will be regarded as Day Zero, if there are no fresh clinical signs of disease.
(a) Day Zero is the last day on which animals on the property were vaccinated for the first time. In the case of two vaccinations, Day Zero remains the last day on which animals on the property were vaccinated for the first time. If clinical signs of disease are still present in the herd at the time of vaccination, the provisions of clause 15.2 will apply, and Day Zero will move to a later date as determined by the state veterinarian.
(b) If any animals from another infected property are introduced onto the premises, all animals will assume the Day Zero of the group with the most recent Day Zero.
