Via T&P (translated from La Razón):
According to the account of the facts, the teacher was explaining the different climates in a geography class and cited the village of Trevelez due to its cold and dry climate. According to the newspaper account, ”as a story, the teacher told his students that such a climate was conducive to making hams (this refers to the procedure that it’s necessary between the pig is killed and the ham is actually ready to be eaten). Then the student asked the teacher not to speak of hams since it offended him, because he was a Muslim. “
