We cannot eat pork because of the express prohibition of it in the Holy Quran: “Forbidden unto you (for food) are carrion and blood and swine flesh…” (The Holy Quran 5:3).
Your obligation is to offer shortened prayers, but if the number of days you are travelling become greater than the days of stay in your home town, then you should offer full prayers while travelling. If you stayed in your town, or any other town for more than ten days, and then started to be a frequent traveller – as explained – then you should offer shortened prayers for the first travel and then continue afterwards offering full prayers.
