“Say, “I do not find within that which was revealed to me [anything] forbidden to one who would eat it unless it be a dead animal, or blood spilled out, or the flesh of swine – for indeed, it is impure – or it be [an animal slaughtered in] disobedience, dedicated to other than Allah . But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], then indeed, your Lord is Forgiving and Merciful.” [The Qur’an al-An’aam 6:145]
Furthermore, it is not only Muslims who refrain from eating pork, with both Jews and some Christian denominations refraining from doing so, and the Old Testament describing pork as “unclean for you.”
Pigs themselves have been plagued by a variety of hazardous infections and diseases, including Porcine Reproductive and Respiratory Syndrome, Nipah Virus, Porcine Endogenous Retrovirus, Hepatitis E, Swine Flu, Menangle Virus, and others, many of which have lead to infections in human beings.
