EFSA has published three scientific opinions on the welfare of pigs, sheep and goats, chicken and turkeys during the slaughter process. The opinions propose monitoring indicators to be used and sampling protocols to be put in place at slaughterhouses.

This scientific opinion proposes toolboxes of welfare indicators for developing monitoring procedures at slaughterhouses for pigs stunned with the head-only electrical method or carbon dioxide at high concentration. In particular, the opinion proposes welfare indicators together with their corresponding outcomes of consciousness, unconsciousness or death. The opinion proposes a toolbox of indicators and the outcomes to be used to assess consciousness in pigs at three key stages of monitoring: (a) after stunning and during shackling and hoisting, (b) during sticking and (c) during bleeding. Various activities—including a systematic literature review, an online survey and stakeholders’ and hearing experts’ meetings—were conducted to gather information about specificity, sensitivity and feasibility of the indicators that are to be included in the toolboxes for monitoring welfare. On the basis of information gathered during these activities, a methodology was developed to select the most appropriate indicators that could be used in the monitoring procedures. The frequency of checking differs according to the role of each person with responsibility for ensuring animal welfare at slaughter. The personnel performing stunning, shackling, hoisting and/or bleeding will have to check all the animals and confirm that they are not conscious following stunning. For the animal welfare officer, who has the overall responsibility for animal welfare, a mathematical model for the sampling protocols is proposed, giving some allowance to set the sample size of animals that he/she needs to check at a given throughput rate (total number of animals slaughtered in the slaughterhouses) and tolerance level (number of potential failures—animals that are conscious after stunning; animals that are not unconscious or not dead after slaughter without stunning). The model can also be applied to estimate threshold failure rate at a chosen throughput rate and sample size. Finally, different risk factors and scenarios are proposed to define a ‘normal’ or a ‘reinforced’ monitoring protocol, according to the needs of the slaughterhouse.
