3 1 Fundamentals The collection, documentation and feedback of diagnostic data are important tools for the management of animal health in poultry herds and therefore play a key role in quality assurance. The documentation of the diagnostic data of all slaughter batches of broilers and turkeys in a central database forms the basis for comparative evaluations. 1.1 Responsibilities Transfer of recorded diagnostic data to the QS diagnostic database is the responsibility of the abattoirs. They must comply at all times with the requirements of the QS scheme and always be in a position to demonstrate compliance with said QS requirements. 1.2 Scope All abattoirs in the QS scheme report diagnostic data from the slaughtering process to the central diagnostic database. No separate authorisation of the abattoirs by the livestock owner is necessary, as this authorisation is already governed by the declaration of participation. The diagnostic data must be reported for all broilers and turkeys delivered by livestock owners that participate in the QS scheme. All abattoirs that record diagnostic data must ensure that their process is in line with this. 2 Findings 2.1 Which diagnostic data are recorded? The poultry industry has conducted pilot projects on the recording and feedback of diagnostic data from poultry slaughtering together with Osnabrück University. The insights gained from these projects are being incorporated in the systematic recording of diagnostic data within the QS scheme. The following diagnostic data must be recorded for each slaughter batch and reported to the central diagnostic database for poultry: Mortality during fattening (animals that died or were culled during the fattening period) Animals that died during transport Footpad changes (score) 3 Data transfer 3.1 Which data must be transferred? The following data must be recorded for each poultry slaughter batch: Abattoir ID (performed automatically via registration) Main destocking/pre-destocking Number of slaughter batch Shed number/shed designation (optional) Slaughter date Number of animals delivered for slaughter Location number of livestock owner Animal species/animal group (turkeys, broilers) Gender (optional, only for turkeys) Mortality during fattening (in percent (%)) Animals that died during transport (in percent (%)) Footpad score Figures of 2b >20% in broilers or C >25% in turkeys Recording system, camera-based Page 3 of 8

Footpad score broilers: Determination of the percentage of animals with footpad changes in the stages 0, 1, 2a, 2b Multiplication of the percentage in the respective stage by the assessment factors 0 for stage 0, 0,5 for stage 1, 1 for stage 2a, and 2 for stage 2b The sum of the results for the individual stages is the footpad score for the slaughter batch Page 4 of 8

5 Tab. 2: Calculation example for the footpad score of poultry fattening Stage Percentage Assessment Calculation Result Stage 0 60% 0 60 x 0 0 Stage 1 20% 0,5 20 x 0,5 10 Stage 2a 10% 1 10 x 1 10 Stage 2b 10% 2 10 x 2 20 Result of footpad score 40 Result for footpad score: the slaughter batch has a footpad score of 40 Note: the value for the footpad score is between 0 (all animals in stage 0) and 200 (all animals in stage 2b). Footpad score turkeys for fattening Determination of the percentage of animals with footpad changes with the scores 0, 1, 2, 3, 4 according to Hocking (et al. 2008) Multiplication of the percentage in the respective stage by the assessment factors 0 for stage A (sum of scores 0 and 1), assessment factor 0,5 for stage B (sum of scores 2 and 3), assessment factor 2 for stage C (score 4). The sum of the results for the individual stages is the footpad score for the slaughter batch Tab. 3: Calculation example for the footpad score of turkey production Stage Percentage Total percentage Assessment Calculation Result Score 0 30% Stage A Score 1 30% Score 2 20% Stage B Score 3 10% Score 4 10% Stage C 60% 0 60 x % 0,5 30 x 0, % 2 10 x 2 20 Result of footpad score 35 Result of footpad score: the slaughter batch has a footpad score of 35 Note: the value for the footpad score is between 0 (all animals in stage A) and 200 (all animals in stage C). Please note: These findings are recorded on a stock basis and for each slaughter batch. The listed assessment criteria represent a minimum standard. In addition, each abattoir can survey further parameters and/or deepen the parameters already included in the minimum standard. Reporting of the data to the central diagnostic database must always be in line with the stipulations listed in Tab. 1. Details of mortality during fattening must only be provided at main destocking. These details are not required for pre-destocking. Page 5 of 8

6 Recording systems Abattoirs with a slaughtering capacity of more than 500 turkeys or broilers an hour must record diagnostic data using a camera-based system from 1 st January 2018 on. If footpad changes are recorded using a camera-based system, all animals in a slaughter batch must be considered. Even if there is a failure in the camera-based system, recording of footpad changes must be ensured for each slaughter batch manually/visually based on a suitable sample size. If footpad changes are recorded manually/visually, at least 100 pairs in a slaughter batch must be assessed (50 pairs at the start and 50 pairs at the end of slaughtering). The quality of data recording must be regularly monitored. The requirements for this monitoring process must be defined in the in-house quality management system. The sensitivity, specificity and reproducibility of the results of the recording of footpad changes must be defined in the company, known to the competent employees and documented in a way that is comprehensible to third parties. Factors such as light conditions and, where applicable, other influencing factors in the case of camera-based systems must be taken into account. In addition risk-oriented analysis of the recording system must be performed and, where necessary, corrective actions must be taken. Proof of these actions must be provided during the audit. 3.2 What reporting options are there? The diagnostic data can be entered into the database in two different ways: Uploading of a csv file via Automated data transfer via an interface from the abattoir s IT to the diagnostic database 3.3 Data access Only authorised users can access the data in the diagnostic database. Access to the database is provided after registration of the user. After signing a data and copyright protection declaration, each user receives a user name and a password from the database administration. a) Abattoir Abattoirs report diagnostic data to the central diagnostic database. They can also commission a third party to report the diagnostic data. Abattoirs and third parties commissioned to report the diagnostic data can view, change (verifiably), delete (verifiably) and download all data that they have entered in the diagnostic database. Access to and viewing of data entered by other abattoirs is only possible if the livestock owner has released the data. On the grounds of data protection, also within the abattoir, downloading all data of an abattoir is only possible based on a separate access to the database. Abattoirs can apply for such access at the database administration. This rule ensures that due consideration is paid to the special need to protect data, also within the abattoir. Page 6 of 8

7 b) Livestock owner Livestock owners are provided with access to their data after the working group diagnostic data poultry has carried out an assessment of the received data and has coordinated the requirements for data access. c) Coordinators Coordinators are provided with access to the diagnostic data after the working group diagnostic data poultry has carried out an assessment of the data and has coordinated the requirements for data access. In addition, it must be determined whether coordinators are permitted to view and download the data of all livestock owners they coordinate. (Data access also dependents on the content and scope of the information that the coordinators, where applicable, should feed back to the livestock owners.) d) Third parties (e.g. consultant, veterinarian, production association, consultancy circle, food retail) Here, it must be determined who is permitted to perform the function of "third party" and which information the third party should receive. e) Veterinarians / Official veterinarians in the abattoir Here, it must be determined whether veterinarians should be provided with access to the diagnostic data. f) QS Qualität und Sicherheit GmbH As scheme owner, QS has access to all data and evaluation results in the diagnostic database. Access to the data is restricted to individual authorised employees of QS. QS will provide the operating company of the animal welfare initiative Initiative Tierwohl access to information that is defined for the implementation of the Animal Welfare Initiative in this respect. For this purpose, it is necessary to determine together with the representatives of the animal welfare initiative Initiative Tierwohl which data are relevant and how the data can be provided. The data in the diagnostic database can be made available to research establishments (e.g. universities, colleges, and Federal Institute for Risk Assessment (BfR)) for research projects and scientific evaluations in the field of animal welfare/animal health after pseudonymisation of the location number (e.g. based on the VVVO) of the agricultural businesses and the identification number of the abattoir while ensuring appropriate data protection. 4 Evaluation of the diagnostic data The working group diagnostic data poultry is drawing up a proposal for the evaluation of the diagnostic data.
