Risk of introducing new variant Influenza A/H1N1 (Swine Flu) to the UK pig population
DEFRA advise that a possible route for disease introduction into pig herds in the UK would be through direct or indirect contact of an infected person with a pig farm or workers on a pig farm. Livestock workers recently returning from Mexico (or nearby states of the USA) and/or showing symptoms of an infectious disease should not have contact with pigs or pig farms.
For more information see the information for pig keepers about Swine Flu on the DEFRA Web Site.
