<<Disclaimer: Verify this information before applying it to your situation.>> Hello all! I spoke with the nutritionist from Boar's Head provisions which produces cold cuts, cheeses and condiments. She said all the meats are GF EXCEPT for their dutch loaf, pickle and pimento loaf and olive loaf. The loafs all have vinegar and they cannot guarantee the source. They have tested their American cheese (both white and yellow), blue cheese and Mozzerella all of which are GF. In addition, their deli style and honey mustard are GF as is their horseradish. Happy eating. Emily
