Pork does not exist in the Omani diet as it is prohibited by Islam. The Omani culture is sensitive towards the choices that expats make with regards to their food and will allow an expat to purchase pork products in the supermarket and eat pork in a restaurant. However both establishments have very strict rules that they follow when cooking or selling pork products.
