How do I reduce disease risk in poultry environments?

Practical steps to protect against avian flu in poultry environments

Avian influenza remains one of the biggest ongoing threats to poultry operations across the UK.

For producers, the impact goes far beyond animal health. An outbreak can mean enforced culling, movement restrictions, lost revenue, and long-term disruption to the business.

The challenge is that disease risk can never be completely removed. But it can be significantly reduced with the right controls in place.

This comes down to one thing: biosecurity that works in real-world conditions, every day.

Understanding how avian flu spreads

Avian flu spreads quickly once it enters a poultry environment. The most common transmission routes include:

• Wild birds and contaminated droppings

• Foot traffic, clothing, and equipment

• Vehicles moving between sites

• Feed and water contamination

• Airborne particles within enclosed housing

While most farms focus heavily on visible contamination, airborne transmission is often underestimated, especially in high-density poultry sheds.

In enclosed environments, pathogens can circulate continuously through dust, dander, and moisture in the air.

Where traditional biosecurity falls short

Standard biosecurity measures remain essential. These typically include:

• Controlled site access

• Disinfection points

• Protective clothing

• Cleaning and downtime between flocks

These steps reduce the risk of disease entering the site.

But once pathogens are inside the shed, they can persist and spread through the air, making them much harder to control.

This is where many systems reach their limit.

The missing layer: air sterilisation

Air quality plays a critical role in disease control, particularly in intensive poultry environments.

Air sterilisation units add an additional layer of protection by continuously treating the air within the shed.

Solutions such as Ilimex’s Fluefence system are designed to:

• Reduce airborne pathogens, including viruses and bacteria

• Lower overall microbial load in the environment

• Improve hygiene levels between full cleans

• Support existing biosecurity measures rather than replace them

Rather than relying solely on prevention at entry points, Ilimex Fluefence helps manage risk throughout the production cycle by supporting cleaner air within the poultry environment.

This additional layer of environmental control strengthens overall biosecurity and helps create more resilient poultry operations.

Why this matters for avian flu

Avian flu can spread rapidly in enclosed poultry systems due to:

• High stocking densities

• Limited air exchange in colder months

• Recirculation of contaminated air

By reducing airborne viral load, air sterilisation helps to:

• Lower the likelihood of disease transmission within a flock

• Reduce environmental contamination

• Support overall flock resilience

It’s not a single fix, but it is a critical layer in a broader disease prevention strategy.

Practical steps to reduce disease risk

To effectively reduce avian flu risk, farms should take a layered approach:

1. Strengthen external biosecurity
Control access, enforce hygiene protocols, and minimise cross-site contamination.

2. Maintain rigorous cleaning routines
Ensure sheds, equipment, and vehicles are regularly cleaned and disinfected.

3. Monitor flock health closely
Early detection remains key to limiting spread.

4. Improve air hygiene within sheds
Introduce air sterilisation to reduce airborne pathogen load.

5. Review and adapt regularly
Biosecurity should evolve alongside emerging risks and operational changes.

A more resilient approach to disease control

Reducing disease risk is no longer just about keeping pathogens out.

It’s about managing the environment inside the shed just as carefully as the risks outside it.

By combining traditional biosecurity with air sterilisation, poultry producers can take a more proactive, controlled approach to avian flu risk, protecting both flock health and business continuity.
