Avian Influenza H5N1: Risks, Prevention and PPE

How Avian Influenza Spreads

H5N1 can cause high mortality among wild birds, including waterfowl and migratory species. Transmission occurs through contaminated water, droppings and direct contact between animals. Outbreaks may lead to large-scale mortality among wild bird populations. The virus spreads rapidly via water and faeces, particularly at densely populated resting areas where birds gather in close proximity.

What to Do if You Find Dead or Sick Birds

If you encounter sick or dead birds, it is important to avoid direct contact. Do not touch carcasses and keep pets at a distance. Report the finding to the landowner, local authority or animal rescue service so the bird can be handled safely and hygienically, reducing the risk of further spread.

Avian influenza occurs periodically across Europe. Authorities such as the European Food Safety Authority (EFSA) and national agencies monitor infections and publish guidance on prevention and control.

For official updates and recommendations, consult the information pages of EFSA and the relevant national authorities. These sources provide measures and advice for professionals.

Impact on the Poultry Sector

A (suspected) outbreak of avian influenza can have significant consequences for poultry farms, including enhanced biosecurity measures, increased monitoring, transport restrictions and, in some cases, culling. For this reason, prevention through hygiene practices, visitor control policies and the use of personal protective equipment (PPE) is an essential part of day-to-day operations in the sector. The risk to humans is generally low, but it may increase in cases of intensive, unprotected contact with infected animals.

Cooperation and Protocols

Effective control of avian influenza requires close cooperation between authorities, industry organisations, land managers and animal health response organisations. Clear protocols for hygiene, reporting and safe handling enable swift and consistent action when infection is suspected or confirmed. Well-defined responsibilities and communication procedures further help to minimise delays and reduce the risk of secondary spread.

Preventing avian influenza begins with proper hygiene and protective measures. Avoid direct contact with wild or dead birds and ensure that poultry and waterfowl are adequately separated from wild animals. Regularly clean and disinfect footwear, vehicles and equipment that come into contact with animals or their environment.

During activities where there is potential contact with (possibly) infected animals, materials or environments, it is important to wear the appropriate personal protective equipment (PPE), such as:

• Body protection (disposable coveralls or liquid-repellent coveralls)
• Foot protection (rubber boots combined with overshoes)
• Hand protection (virus-resistant nitrile gloves)
• Respiratory protection (FFP2 or FFP3 respirator)
• Face protection
• Hair nets (single-use)

Proper PPE prevents contamination from being carried on clothing, skin or through respiratory exposure.

Coordination and Biosecurity Guidelines

Authorities and industry bodies share surveillance data and publish biosecurity guidance on avian influenza. Hygiene protocols, visitor procedures and biosecurity measures are developed to help reduce the risk of disease introduction and spread within poultry operations.

Influenza Vaccination for Occupational Risk Groups

For professionals with intensive contact with (potentially) infected animals, additional medical guidance may apply, such as seasonal influenza vaccination. This can help reduce the risk of co-infection. Consult your national public health authority or occupational health provider for current recommendations.

Health Measures for Personnel

Organisations involved in culling, animal handling or the management of infected animals typically implement health monitoring procedures and provide clear safety instructions for employees.

If flu-like symptoms develop within ten days following potential exposure, individuals should seek medical advice and inform the healthcare professional about the possible contact with infected animals.

Working Together on Prevention

Avian influenza highlights the importance of hygiene, personal protective equipment (PPE) and close cooperation between government authorities, industry stakeholders and response organisations. With clear protocols, appropriate protective measures and effective monitoring, the risk of infection can be kept under control.

In cases of (suspected or confirmed) infection, thorough cleaning and disinfection of housing units, equipment and animal facilities are essential to reduce the risk of recontamination. Safety Products supplies suitable PPE for these tasks, including chemical-resistant and waterproof protective clothing, safety boots and hand protection with high chemical resistance.

With certified personal protective equipment, cleaning and disinfection work can be carried out safely and hygienically, even when using powerful cleaning agents or disinfectants. Proper PPE also helps prevent cross-contamination between zones and reduces the risk of exposure to chemical agents during application.
