@Kanysh0You were certainly a good host to your guest from Paris.
Who knows why he didn't deliver the sausage.
The only thing you could have done before you asked him to take it is to check on-line whether he can take meat products into the EU from a country from outside the EU. This is forbidden unless he had documents which cover all relevant aspects of hygiene, animal health and public health of the country the meat came from. The favour you asked could have caused problems.
I'm sure it's delicious and it was a pity your friend's friend didn't get their treat.
