<<Disclaimer: Verify this information before applying it to your situation.>> Unsalted Fleishman's margarine does not contain any dairy in it. It says "lactose free" on the label but it also doesn't have any casein in it. Lactose is a sugar. Casein is a protein. They are not the same. Unsalted Fleishman's also has the Parve symbol on it. Beware--Bumble Bee solid white tuna in water has caseinate in it. Also noticed by the D in the circle on the label. I never would have thought to look for casein in tuna! Jean
