Mozzarella (; ) is a cheese, from southern Italy, traditionally made from Italian buffalo milk by the pasta filata method. Mozzarella received a Traditional Specialities Guaranteed certification from the European Union in 1998. This protection scheme requires that mozzarella sold in the European Union is produced according to a traditional recipe. The TSG certification does not specify the source of the milk, so any type of milk can be used. In Italy mozzarella made with the milk of the Italian water buffalo is an important variety. The Italian buffalo mozzarella sold as Mozzarella di Bufala Campana is protected under the EU's Protected Designation of Origin scheme and may only be produced in select locations in the regions of Campania, Lazio, Apulia and Molise. American 'mozzarella' can be made from pasturized cow's milk.
