In a bit from the cable TV comedy “Portlandia,” a couple orders chicken at a restaurant, and the server returns with a dossier, topped with a photograph: “The chicken you’ll being enjoying tonight, his name was Colin,” she says. “Here are his papers.” Today’s consumers are demanding nearly that level of transparency in their meat and poultry. And the technology exists to give it to them. Transparency and traceability are in great demand in food generally, and meat/poultry is arguably where the demand is most intense.
