Free-range egg producers are being reminded of the importance of investing in strong biosecurity measures following a surge in cases of avian influenza (AI) this season.
The plea from Gabriella Whorwood, head of contract production at Stonegate, comes against the backdrop of more than 90 AI cases being reported across the UK since October.
“This season is far from over and we’ve already exceeded the entire 2024/25 season when 82 cases were confirmed,” said Whorwood.
“This is happening at the same time a surge in demand for free-range eggs is delivering attractive returns for farmers, with the value of the market up by more than 50% in the past three years and the sector forecast to grow by more than 10% by 2030.”
She says producers should use the strong demand for eggs – coupled with strong farmgate prices – as both an impetus for doubling down on biosecurity and a means of funding infrastructure improvements to achieve this.
“Although it’s not possible to completely eradicate the risk of AI to flocks, a focus on infrastructure maintenance and improvements will go a long way in reducing the risk of the disease,” said Whorwood.
“Poor building maintenance is one of the most common causes for disease entering flocks.
“Taking the time to invest in infrastructure through measures such as improvements to guttering systems and rodent proofing will help reduce this route of transmission and safeguard businesses in the years ahead.”
She says good quality guttering systems are essential for mitigating the risk of AI and other diseases entering housing through water.
“Water is a key source of contamination and AI can live in cold water for 100 days, or more,” said Whorwood.
“This highlights the importance of ensuring guttering systems are in good working order and the need for regular checks for water leaks.
“In addition, farmers should pay close attention to hard standing areas and drainage to remove water from around buildings.”
She said other example areas for investment include rodent proofing premises – paying close attention to areas around muck belts and egg belts – and ensuring wheel washing facilities cover the whole wheel of vehicles coming in and out of the farm.
“Farmers should also review any gates and fencing they have in place around the farm to boost structural biosecurity and minimise the number of people on site,” said Whorwood.
“The team at Stonegate is more than happy to provide support to producers around infrastructure improvements to boost biosecurity, and any wider biosecurity queries in general.
“This is part of our commitment to offering full lifecycle support to our suppliers – including AI insurance – to provide peace of mind and ensure they have sustainable, profitable, welfare-led enterprises.”
