Outbreaks of animal diseases are well documented throughout modern history. Major outbreaks have damaging consequences for animal welfare, for the industry and often cause major disruptions in food supply, especially within the poultry industry. In order to avoid these consequences, killing methods and techniques have been developed to kill poultry on farm, as well as development dedicated emergency plans, guidelines, procedures to shoulder efforts to reduce and prevent large-scale outbreaks.
Despite all these efforts in the past, outbreaks continue to occur. New, integrated methods for culling and disposal must be developed to combat outbreaks that cannot be mitigated or prevented by vaccination. These methods should be capable of supporting large-scale, quick culling campaigns and cadaver disposals without further spreading of diseases, transfer to humans, or putting a liability on the environment. In the EU, although Regulation 1099/2009 covers culling operations, the present techniques often are not compliant, or are often applied in an improper way.
On March 17, 2014, Dr. Lotta Berg, one of Europe’s leading experts in this field and Swedens' representative within the European Food Safety Authority EFSA, presented at Neiker Tecnalia in Victoria-Gasteiz (Spain) her vision on emergency response, referring to the EU Directive EU 1099/2009. She covered in her presentation the following subjects:
• Different types of poultry and poultry production
• Reasons for euthanasia
• Large‐scale emergencies
• Contingency planning
• Monitoring animal welfare at on‐farm killing
• Critical points, follow‐up and reporting
• Different methods in practice
• Non‐emergency euthanasia
Dr. Berg concluded in her presentation that the Anoxia technique (N2 gas foam) is applicable for killing poultry on small-, medium- and large-scale poultry operations.
