The Government has confirmed H5N8 avian flu in a backyard flock near Thornton, Wyre, Lancashire.
Two outbreaks of bird flu have been reported within just days of each other in Lancashire.
It comes after a number of birds in a flock of about 30 chickens died at a farm near Thornton on Thursday and a small backyard flock of chickens and ducks at a nearby farm near Thornton-Cleveleys was confirmed to also have avian flu on Saturday.
A Defra spokeswoman said: "A full investigation is under way to determine the source of the infection" and confirmed a 3km protection zone and a 10km surveillance zone have been put in place around the infected premises to limit the risk of the disease spreading.
Public Health England made assurances that the risk to public health from the virus was very low and the Food Standards Agency said it did not pose a food safety risk.
Measures to be lifted
The Government has only recently decided to relax the Avian Flu Prevention Zones and a ban on poultry gatherings, which are set to be lifted across England from 15 May.
The Government still advises keepers to follow industry standard best practice on biosecurity, including minimising movement in and out of bird enclosures, cleaning footwear, keeping areas where birds live clean and tidy and feeding birds indoors.
Despite the outbreaks this weekend, the most recent case of H5N8 in poultry in England was confirmed on 24 February 2017 and the last finding in wild birds was on 10 March 2017.
In March, millions of UK free range eggs temporarily lost their status after hens were forced to spend weeks inside barns as part of the government's emergency bird flu measures.
