Produced in Italy, Callipo Yellowfin Tuna Fillets are hand-cut using the richest and most tender part of the tuna, then hand-packed in water. This choice yellowfin tuna boasts a lovely light pink color and tender, juicy taste. Callipo Yellowfin Tuna Fillets are 100% natural and dolphin safe. Founded in Pizzo, Italy, a seaside town known for tuna fishing, Callipo has been processing its high-quality fish using traditional methods since 1913.
