That article mentions that the sow bit the farmer because he stepped on her piglet. That`s understandable. Boars will butt someone too if they feel threatened but just because a pig bites someone, it doesn`t mean it will eat someone. That`s ridiculous
I just don`t think a pig would bite into such a huge lump of meat (a human). I know they`re omnivores. My father`s pigs used to be fed on swill that was collected every morning from the local hotels (meat and veg) but I just can`t imagine a pig eating a human body (unless it was already cut into small pieces).
