Dear Mr XXXXXXXX
Thank you for your email enquiry of the 16[SUP]
th[/SUP] April 2013, regarding the import, into the UK, of wild boar meat for personal consumption, following a boar hunting trip to France.
You may import the boar meat, however, the carcass must have received an official meat stamp in the country of export and therefore would need to go to an approved cutting plant.
The import requirements of the trophies would depend on what treatments they have undergone. If they have been through the process of taxidermy, are fully processed, mounted & ready for display and are not requiring any further processing in the UK, they would be deemed finished products and therefore, there would be no Animal Health import requirements. If the above is not the case, please provide more information in order for us to advise you further.
We would advise you to contact CITES for any requirements they may have and their contact details can be found via the following web link:

Please read all the information carefully and ensure that you are able to fully satisfy all the conditions and requirements.
Regards

P.S. Not sure where I got the 1kg of meat notion from, it may be a bit of a red herring
