2007 Bernard Matthews H5N1 outbreak

It was the third instance of H5N1-subtype detected in the United Kingdom and a range of precautions were instituted to prevent spread of the disease including a large cull of turkeys, the imposition of segregation zones, and a disinfection programme for the plant.

[1] A bird-adapted strain of H5N1, called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu.

The first outbreak occurred in October 2005 among exotic birds imported from Taiwan and South America at a privately owned quarantine facility in Essex, England.

[17][18] It emerged in a highly critical report from Defra that there was a series of biosecurity failings at the Holton plant, some of which were drawn to the company's attention in the past.

[19][20] Defra minister Jeff Rooker stated in a House of Lords debate on 22 February that the outbreak was "exclusively a Bernard Matthews Holton problem".

[21] The Government, on 8 February, admitted that the outbreak may have been caused by semi-processed turkey meat imported directly from Hungary, where the disease is prevalent, despite earlier in the week the Environment Secretary, David Miliband assuring the House of Commons that there was "no Hungarian connection".

Though Saga Foods lies 165 miles (266 km) from where the recent Hungarian H5N1 outbreak had occurred, a company director admitted it was "possible" that some of the meat could have come from the exclusion zone.

[26] Even so, the H5N1 bird flu strains found in Hungary and Britain were shown to be 99.96% genetically identical and, according to an analysis of the viruses by the Veterinary Laboratories Agency in Weybridge, Surrey, were almost certainly linked.

[27] A leak from the Government's COBRA emergency committee indicated that the authorities were not aware of the Hungarian connection until an investigator found a Gallfoods delivery wrapper in a Bernard Matthews bin.

This abattoir might have been a middle man for contaminated poultry farming tools, feed, or product from within the restricted zone, such as a Bernard Matthews owned subsidiary in Hungary.

"[29] Bernard Matthews was given permission to resume its shipments of poultry between the UK and Hungary from 17 February even though Defra indicated that Hungarian turkey products remained the "most plausible" cause of the outbreak.
