Seven poorly penguins at Marwell Zoo are to be reunited with their feathered friends following an outbreak of avian influenza last month.

The penguins were placed in isolation after the outbreak was identified, but have since tested negative for the virus.

The flamingos at the zoo were also tested as a precaution and were found to be negative.

To prepare for the penguins' return to their enclosure, a thorough program of cleaning and disinfection must be completed to meet the requirements of the Animal and Plant Health Agency (APHA).

It is expected that this process will be completed by mid to late January at the earliest.

Justine Shotton, veterinary services manager at Marwell Zoo, said that the sooner the penguins can return to their enclosure, the better it will be for their welfare.

She explained that indoor conditions can lead to pododermatitis, a condition that affects the feet, and aspergillosis, a potentially fatal fungal infection.

All of the penguins are currently on antifungal medication and are being monitored regularly to reduce these risks.

Ms Shotton added: “In cases like this, we have to weigh up the risks of having them outside, which allows for much higher welfare standards but with a risk of avian influenza, against the risks of associated health issues and poor welfare if we keep them indoors.”

Avian influenza is now a year-round risk, and Marwell Zoo is taking ongoing measures to reduce the risk to its birds.

In the meantime, access to the walk-through aviaries and Energy For Life: Tropical House will continue to be restricted.
