Want to know something cool?  Genova has started a program called Digital Traceability and it’s pretty awesome. Genova customers simply enter the 10- to 15-digit number located on the bottom of their Yellowfin and Albacore tuna to receive answers to six specific questions:

  1. What is My Tuna? Visitors are given an initial description of their tuna or other seafood species.
  2. Where Was My Tuna Caught? These results include a world map showing the Food and Agriculture Organization (FAO) Area where the tuna or other seafood was caught, and a link to a species-specific stock status report from the International Seafood Sustainability Foundation (ISSF)
  3. What Fishing Method Was Used? This section includes both the fishing method and vessel size.
  4. What Fishing Vessel Caught My Tuna? This information includes fishing vessel name, nation of registry and fishing trip start and end dates.
  5. Where was My Tuna Processed and Canned? The can code indicates where the seafood was processed and canned, which may not necessarily be where it was caught. The processing method is subject to Genova’s strict compliance requirements andstringent Business Ethics and Labor Code of Conduct.
  6. How Does Genova Support Sustainability?

I love working with companies who are doing their part to show us where our food is coming from!

    So delicious! I was short on time so subbed in a Trader Joe’s cauliflower pancake for the sweet potato as a quick cooking alternative. Super yummy! Thank you for yet another great recipe 🙂

  3. Hey Lexi, it doesn’t seem to show me the ingredient list – but I know I’ve made this in the past many times! Is it showing up on your end or is there maybe a bug to fix? Thanks!

  5. I pack food for my husband who works away from home 3 days/week at a location with only one restaurant within 30 miles- Is this something That can be put in a container and reheated 2 or 3 days later? Or is this something best eaten the same day? Thanks!

  6. Made this today for lunch, what a great idea! And filling! I don’t like celery… and usually put pickle relish in my tuna… but today tried PINEAPPLE! It was tasty. Topped with avacado and melted swiss. Good lunch. Thanks for sharing 🙂

  7. waw… Can’t control my tongue! Looks very delicious to me. I am going to try it up right now. Thanks Lexi. Reading this post is really fun to me. Just loved it:)

  8. I can’t get enough of this recipe!! I made it for lunch and have leftover tuna salad I can’t wait to eat for lunch later in the week. So so delicious! Also, such a clever idea to make a melt with the sweet potato buns. Definitely a KEEPER!
