If you read the link it’s about weight per can not origin of tuna
This is a product that has been shrinking steadily. Used to be 6 oz. Now it's 5 oz. Small cans used to be 3 oz. Now I think it's 2.5. Of course, the price has gone up.
We bought our share of the water packed tuna over the years. The shortchanged amount probably doesn’t add up to the settlement but that is the deal that was cut. Went for the $25, cash in this Obamaeconomy helps.
