Biosecurity to Prevent Avian Influenza

Biosecurity is a set of preventative measures designed to reduce the risk of transmission of infectious diseases, the objective being that 'prevention is better than cure'. It uses a set of management and physical measures designed to reduce the risk of introduction, establishment and spread of animal diseases.

Poultry owners should be familiar with the Clinical Signs of Avian influenza and report any suspicion of disease to their local Regional Veterinary Offices without delay.

DAFM has produced some biosecurity factsheets for Biosecurity Advice for Backyard Poultry Owners, and Biosecurity Advice for Turkey Owners flocks along with more detailed biosecurity information for General Biosecurity Advice for Commercial Flock Owners.

During the migratory wild bird season between October and April each year the risk of an Avian influenza outbreak increases. At this time, Additional Biosecurity Measures for Avian Influenza in High Risk Periods may be needed by poultry owners.

1) Segregation

This is the most effective pillar of biosecurity. This means preventing contact between an animal which could catch a disease and a potentially contaminated animal, object or person. This doesn’t just mean using physical barriers like walls, but also means restriction of access e.g. personnel. Other biosecurity measures could include not sharing equipment/tools/machinery.

2) Cleaning

Removing all visible dirt and contamination can remove up to 99% of disease causing agents.

3) Disinfection

Always use a Department of Agriculture DAFM Approved Disinfectants made up and used in accordance with the manufacturer’s instructions, for example: contact times.
