  That it's possible, does not mean that this solutions were used in this case. In the first place the FDA did not test here, just unamend labs. And it should also be noted that it seeme that there are other means of processing besides cooking which can make the meat harder to identify. The Article reads as if they tested against a preselected choice of possible results, not the full FDA-database. The only result here is that they were unable to identify the origin of this food. But we don't know whether this happend because they were lacking data, or the processing made it not possible to identify it, or whether it really is not tuna. We only know they could not identify it as tuna.
