Because Allah had forbidden it.

“Say (O Muhammad): I find not in that which has been revealed to me anything forbidden to be eaten by one who wishes to eat it, unless it be Maytah (a dead animal) or blood poured forth (by slaughtering or the like), or the flesh of swine (pork); for that surely, is impure or impious (unlawful) meat (of an animal) which is slaughtered as a sacrifice for others than Allaah (or has been slaughtered for idols, or on which Allaah’s Name has not been mentioned while slaughtering)”

[al-An’aam 6:145]

Why is pork haram. Kindly tell me the story if there is.

Conditions of eating meat slaughtered by the Jews and Christians I know that it is essential to say the name of Allaah when slaughtering animals that are to be eaten, and that it is not permissible to eat from that over which the name of Allaah has not been mentioned, but sometimes a Muslim has to travel to a non-Muslim country and stay there for several years, for work or study. Should he refrain from eating meat completely for this length of time or in this case is he regarded as compelled by necessity to eat meat or is it sufficient to say the name of Allaah at the time of eating?.
