"If religious slaughter is done according to the rules, by people who are trained and certified, that should never be a problem in any society", he said, adding that he felt similarly about circumcision.
Mr Timmermans was in part responding to a speech given minutes earlier at the dinner by Rabbi Albert Guigui, chief rabbi of Brussels, who called upon the EU bureaucrat to "join us as our friend and ally in this fight for religious freedom".
In his own speech to the conference, Rabbi Pinchas Goldschmidt, president of the CER and chief rabbi of Moscow, described the Walloon parliament's move as "a position that not only disregards the ample body of scientific evidence that supports shechita as a humane method of slaughter, but also disregards the simple fact that the shechita process conforms with all the norms of animal welfare as well as the European definition of stunning".
Rabbi Goldschmidt also identified "a prominent political party in Norway, a member of the ruling coalition, which seeks to ban circumcision", describing the policy moves in the two countries as "attacks on faith". Norway is not an EU member country.
