In recent years, broiler mortality during transport to the slaughterhouse has become a cause for concern because of animal welfare considerations and associated economic losses. A descriptive and analytical epidemiological study was carried out to estimate the extent of DoA in poultry broiler production in the main producing regions of France and to determine factors influencing the DoA rate. Data regarding animal characteristics and rearing, catching, transport and lairage conditions were collected on farm and at the slaughterhouse for 404 chicken broiler flocks processed during 2005. The average DoA rate was 0.18% (from 0% to 1.4%). Variables found to be associated ( P , 0.05) with the DoA rate in a multivariable negative binomial model were flock cumulative mortality on farm, the catching system (mechanical being more at risk than manual), the density in crates (more space allowance being associated with less mortality) and climatic conditions (rain and wind being associated with more DoA). Mortality during transport is thus related to all production steps from the farm to the slaughterhouse. Efforts have therefore to be made by all professionals to contain mortality on farm and during catching and transportation.

“…The main reasons for condemnation were emaciation and congestion, with rates of 30 and 22 per 10,000 birds slaughtered, respectively. Congestion was significantly associated with arthritis and ascites, whereas infected skin lesions were associated with bruises and abnormalities of colour, odour or conformation (Lupo et al, 2008).…”

Council Directive 2007/43/EC on the protection of chickens kept for meat production requires Member States to submit to the Commission the results of a data collection of welfare indicators in broiler slaughterhouses. The Commission prepared a draft document for a harmonised data collection system of welfare indicators in broiler slaughterhouses for a one-year period and requested EFSA to assess whether the sample size chosen in the document would be sufficient to achieve the objectives of the data collection. The structure of the population as well as possible stratification factors influence the sampling protocol of a data collection. In this case, the sampling should occur in each Member State at three levels: i) at slaughterhouses; ii) at flocks within each sampled slaughterhouse and iii) at broilers and feet within each sampled flock. Based on the methodological approach developed for this mandate, the assessment shows that for 15 MS, 1% of the total number of flocks slaughtered in one year is not a sufficient sample to assess 1% prevalence of the given conditions. For 3 MS, 1% sample is sufficient depending on the combination number of flocks and broilers/feet chosen. For 1 MS, when any combination is used, 1% of flocks slaughtered is a sufficient sample to assess prevalence of 1%. A general approach for designing and ensuring representativeness of sampling plans in MS was proposed. The recommended sampling scheme better fitting for this data collection is a three stage sampling scheme, where the selection of the unit at each level could be based on established criteria. Finally, in the case an EU harmonised data collection is implemented in the future, it is recommended to submit the collected data in a harmonised way through the EFSA Data Collection Framework. This report proposes a possible data model for the submission of the data. SUMMARYArt 6(2) of Council Directive 2007/43/EC 4 laying down minimum rules for the protection of chickens kept for meat production requires Member States (MS) to submit to the Commission the results of the data collection based on the monitoring of a representative sample of flocks slaughtered during a minimum period of one year. The sampling and data collected, as referred to in Annex III of the Directive, should be scientifically based, objective and allow for a comparative analysis. The data to be collected at slaughterhouse is on welfare indicators, for the assessment of the welfare on farm of broilers raised in that MS according to Council Directive 2007/43/EC.The Commission has prepared a draft document proposing a harmonised data collection system of welfare indicators in broiler slaughterhouses. The main objective is to achieve an overall picture in the EU and in each of the 27 MS of the welfare of broilers, in particular detecting those welfare conditions, such as contact dermatitis, systematic illness and mortality, which occur at 1% or greater at EU level. The Commission draft document for the data collection foresees to stratify the sample in two catego...

“…The condemnation rate differed significantly according to the type of poultry produced (standard, light, heavy or certified). Heavy weight flocks had a significantly higher condemnation rate than standard flocks (Lupo et al, 2008). In a national survey in Lithuania during 2000-2009, pathological lesions were identified in 0.95% of poultry, with the majority (98.7%) of registered pathologic lesions typical of non-infectious diseases.…”

Scientific Opinion on the public health hazards to be covered by inspection of meat (poultry)

A qualitative risk assessment identified Campylobacter spp., Salmonella spp. and ESBL/AmpC gene-carrying bacteria as the most relevant biological hazards in the context of meat inspection of poultry. As none of these are detected by traditional visual meat inspection, establishing an integrated food safety assurance system, achievable through improved food chain information (FCI) and risk-based interventions, was proposed. This includes setting targets at carcass level and, when appropriate, flock level indicating what should be achieved for a given hazard. Elements of the system would be risk categorisation of flocks based on FCI and classification of abattoirs according to their capability to reduce carcass faecal contamination. It is proposed that post-mortem visual inspection is replaced by setting targets for the main hazards on the carcass, and by verification of the food business operator"s hygiene management, using Process Hygiene Criteria. Chemical substances that might SUMMARYFollowing a request from the European Commission to EFSA, the Panel on Biological Hazards (BIOHAZ) and the Panel on Contaminants in the Food Chain (CONTAM) were asked to deliver a Scientific Opinion on the public health hazards (biological and chemical, respectively) to be covered by inspection of poultry meat. Briefly, these Panels were asked to identify and rank the main risks for public health that should be addressed by meat inspection, to assess the strengths and weaknesses of the current meat inspection methodology, to recommend inspection methods fit for the purpose of meeting the overall objectives of meat inspection for hazards currently not covered by the meat inspection system, and to recommend adaptations of inspection methods and/or frequencies of inspections that provide an equivalent level of protection. In addition, the Panel on Animal Health and Welfare (AHAW) was asked to consider the implications for animal health and animal welfare of any changes proposed to current meat inspection methods. The three EFSA Panels presented the following key conclusions and recommendations:For biological hazards, a decision tree was developed and used for risk ranking poultry meat-borne hazards. The ranking was based on the magnitude of the human health impact, the severity of the disease in humans, the proportion of human cases that can be attributed to the handling, preparation and consumption of poultry meat, and the occurrence of the hazards in poultry flocks and carcasses. Campylobacter spp. and Salmonella spp. were considered to be of high public health relevance for poultry meat inspection. Extended spectrum -lactamase (ESBL)/AmpC gene-carrying bacteria were considered to be of medium to high (E. coli), and low to medium (Salmonella) public health relevance. Data for ranking C. difficile were insufficient, but based on the limited information available, the risk at the present time was considered to be low. All other hazards were considered to be of low public health relevance.Risk ranking of chemical hazards was...
