According to Sunan Ibn-I-Majah Volume 3, Book of Intoxicants, Chapter 30 Hadith No. 3380.
It was reported by Anas (may Allah be pleased with him), that Prophet Muhammad (pbuh) said: "God’s curse falls on ten groups of people who deal with alcohol. The one who distills it, the one for whom it has been distilled, the one who drinks it, the one who transports it, the one to who it has been brought, the one whom serves it, the one who sells it, the one who utilizes money from it, the one who buys it and the one who buys it for someone else."
Pork has a similar. No are you allowed to touch, nor use its skin for any clothing or accessories.
Muslims should be careful who work in supermarkets. If you handle pork or alcahol, or shelf it or pack it for someone their crime is now your head aswell.
