[F1ANNEX II U.K. DETERMINATION OF BSE STATUS

CHAPTER D U.K. Minimal surveillance requirements

3. Points values and point targets U.K.

Surveillance samples must meet the point targets set out in Table 2, on the basis of point values fixed in Table 1. All clinical suspects shall be investigated, regardless of the number of points accumulated. A country shall sample at least three out of the four sub-populations. The total points for samples collected shall be accumulated over a period of a maximum of seven consecutive years to achieve the target number of points. The total points accumulation shall be periodically compared to the target number of points for a country or region.

Table 1

Surveillance point values for samples collected from animals in the given sub-population and age category

a

Bovine animals over 36 months of age at routine slaughter.

b

Bovine animals over 30 months of age which are found dead or killed on farm, during transport or at an abattoir (fallen stock).

c

Bovine animals over 30 months of age that are non-ambulatory, recumbent, unable to rise or to walk without assistance; bovine animals over 30 months of age sent for emergency slaughter or with abnormal observations at ante-mortem inspection (casualty or emergency slaughter).

d

Bovine animals over 30 months of age displaying behavioural or clinical signs consistent with BSE (clinical suspects).
