We appear to have been incredibly lucky. Bird flu has struck a British poultry factory farm and, although 159,000 turkeys were culled to halt the spread of the disease, the slaughterhouse has been disinfected and was up and running again within days of the outbreak.

No neighbouring farms seem to have been affected – and there are certainly no reported cases of the virus infecting people. A few hundred farm workers look set to lose their jobs, but it is business as usual for the global trade in poultry products destined for and manufactured in factory farms.
