Est. 1917. Authentic Italian recipe. Slow aged. No gluten, no MSG, & 0 g trans fat per serving. When the Italian-born founders of Columbus, the Parduccis & Domenicis, came to San Francisco in 1917, they brought their authentic Italian recipes with them. Today, Columbus has become one of the most respected producers of fine foods in the country. We're still a family owned business, and we're still as crazy about making the kinds of premium food people love. Columbus Salumeria's pre-sliced meats are the same superior quality you would expect from Columbus in the service deli case. US inspected and passed by Department of Agriculture Est. 9882.
