Probably because of the high levels of mercury in it.
OK, well I just read some report that said only 5% of tested tuna cans have unsafe levels of mercury in them. Phew. That's a relief. Only 5%. But wait, that's 1 in 20. So, if over the span of your long life, you've had more than 20 cans of tuna...which I think is the case for many of us...certainly is for me...well, you do the math...the odds aren't really in your favor.
Anyway, I do like tuna, mercury-laden or not. And once you get past the mercury risk, there's the whole "dolphin safe" issue. Come to think of it, I didn't really do my homework and make sure TJ's was dolphin-safe. Of course, there are some groups that still claim there aren't any truly dolphin-safe companies in the U.S. and that the whole Department of Commerce Dolphin Safe logo is just a big conspiracy. But then, I'm sure there are some conspiracy theorists who would claim that the government is deliberately trying to kill off the dolphins in order to wipe them out for fear that in several million years they will evolve opposable thumbs, rise up and destroy humanity in revenge for all of their ancestors that died meaningless deaths upon our carelessly-cast tuna nets. That's actually not that far-fetched, really...bah, must be the mercury talking again...
Ahem, moving along...we shall now discuss the semi-deliciousness of the aforementioned Trader Joe's Tuna Salad Wrap. It's moist and tasty. The tuna salad is a good mix of mayo and vegetable bits and seasonings. Sonia actually much preferred this wrap over the Chicken Caesar Wrap we reviewed a week or two ago, but as she pointed out, the tuna wrap still could use a little more kick in the flavor department. I could see how maybe dropping a few banana peppers in the wrap would help it a bit, just like they do with my tuna sandwich at Subway...mmm, now I'm craving Subway.
I guess that if, whilst reviewing a particular food product, one begins craving a completely different company's product, that the former product has not been very memorable or totally satisfactory. I guess I do prefer Subway's tuna sandwich—or even the TJ's Chicken Caesar Wrap, but only by a little. All things considered, the tuna wrap is a nice, fresh snack, but don't expect anything life-changing. This is a "not bad" food all the way. 3.5 out of 5 stars from me. Sonia agrees.
Bottom line: 7 out of 10.
