Cans of tuna in American supermarkets used to hold 6 ounces. Then, a number of years ago, the manufacturers all decided to shrink their cans to 5.5 or 5.45 ounces without lowering the price. More recently, they all decided to go down to 5 ounces, again without lowering the price.
Annoyed by this most recent change, I decided during a recent trip to the grocery store to reevaluate our tuna buying habits rather than blindly continuing to buy StarKist, the brand we had settled upon a number of years ago for unremembered reasons. Therefore, although I did throw a few cans of StarKist chunk light tuna in water, SKU 806730, in my cart, I also threw in a few cans of Stop & Shop’s, SKU 21120 02522, which were needless to say cheaper than the StarKist.
The next time I made tuna salad, I opened two cans of the StarKist and two cans of the Stop & Shop tuna, drained them all, visually inspected them for quality, and weighed the tuna left in the cans after draining. The results surprised me.
