Thank you for all the assurances and suggestions for the future. The meat was cooked very well but the problem I think it's that me and my friends (hunters) were unaware of such a possibility.

We were the ones that brought back, cleaned and prepared the boar with our bare hands with no precautions (we were in the mountains). The only thing that gives me a bit of piece of mind is that several months passed since then and we have no symptoms and I know many other people that have eaten wild boar from that area that have no symptoms.
