Division 2.3 Sampling design

Isolates which are tested for antimicrobial susceptibility as provided for in Article 2 shall be obtained from monitoring programmes, based on randomised sampling design. The bacterial isolates referred to in Article 2 must originate from randomly selected epidemiological units or randomly selected within the slaughterhouses. Where diseased animals are sampled, the result of the antimicrobial susceptibility testing shall be kept separately when reported in accordance with point 2 of Part B.

The competent authority shall ensure the randomisation of the sampling scheme and its correct implementation.

In the case of sampling at slaughterhouses as provided for in point 1 of Part A, sampling shall be performed at slaughterhouses processing at least 60 % of the specific domestic animal population in the F1United Kingdom, starting with the slaughterhouses of largest throughput.

Not more than one isolate per bacterial species from the same epidemiological unit per year shall be included in the monitoring provided for this Decision. The epidemiological unit for laying hens, broilers, and fattening turkeys shall be the flock. For fattening pigs and bovines under one year of age, the epidemiological unit shall be the holding.
