# Commission Decision of 19 July 2007 concerning a financial contribution from the Community towards a survey on the prevalence and antimicrobial resistance of Campylobacter spp. in broiler flocks and on the prevalence of Campylobacter spp. and Salmonella spp. in broiler carcasses to be carried out in the Member States (notified under document number C(2007) 3440) (2007/516/EC), Part A: Sampling frame

Extent: E+W+S+N.I.

To avoid age-related effects the monitoring shall be carried out on slaughter batches at the slaughterhouse.
As prevalence of Campylobacter spp. has been shown to vary significantly depending on the season, this merits stratification. For that purpose a 12-month period must be divided in 12 periods of one month. In each of those periods 1/12th of the total sample size must be taken.
The sampling must otherwise be based on a random selection, both regarding slaughterhouses, sampling days each month and which batches are to be sampled on a selected sampling day. In particular, the randomisation scheme shall guarantee a selection of slaughter batches proportionate to the number of flocks fattened according to the different production types (conventional, free-range, organic). In addition, the Salmonella spp. or Campylobacter spp. status, if known at slaughter, must not bias the randomisation. The competent authority shall take responsibility for generating the randomization scheme and ensuring it is implemented correctly. An example of a randomisation procedure is provided in the Report of the EFSA Task Force on Monitoring of Zoonosis Data Collection on proposed technical specifications for a coordinated monitoring programme for Salmonella and Campylobacter in broiler meat in the EU. Details of the randomisation scheme shall be reported to the Commission.
