Study: poultry biosecu­rity can be improved

Poultry farms can improve the implementation of important biosecurity measures. This is shown by research from Wageningen Bioveterinary Research. Daily routines in particular need attention, such as handwashing and changing footwear. Researchers also identified areas for improvement in transport, supply and egg storage.

Routines under pressure

Researchers monitored the daily implementation of biosecurity measures at several poultry farms over a period of several weeks. They used 24-hour video monitoring for this. The cameras recorded actions and movements at the entrances to farm buildings and poultry houses.

The study took place at different types of farms. These included broiler farms, laying hen farms, breeder farms and a duck farm.

The observations show that simple measures in particular need attention. Hands were rarely washed when entering and leaving the anteroom. Footwear changes were also often unsafe or incomplete.

Focus on transport

Researchers also identified areas for improvement in logistics. After eggs were collected, the poultry farmer did not clean and disinfect the egg storage area. When young broilers and ducks were delivered, transporters and poultry farmers were regularly seen entering the poultry house without changing footwear.

At one farm, litter was delivered in a way that could increase the risk of pathogens being introduced. This means the findings also concern farm visitors and transport around poultry farms.

Proper implementation is possible

One broiler farm stood out in a positive way. There, biosecurity measures were applied consistently and carefully. According to epidemiologist and project leader Armin Elbers, there are no statutory standards for biosecurity measures in the Netherlands.

However, he describes them as logical measures to prevent the introduction of pathogens. This also applies to the avian influenza virus. “Our research shows that consistent implementation is achievable,” says Elbers. The researchers emphasize the need for continued attention to awareness and training. This applies to poultry farmers, employees and farm visitors.
