Does a Subway tuna sandwich contain actual tuna? This is not the set up for a joke line. Rather, it seems to be a real controversy. A genetic test was done was done by the New York Times – not exactly known for truth telling these days – that indicated zero tuna DNA. But, Subway says this result is false because the alleged tuna is so heavily processed that the tuna DNA may not be detected by the test.
Either way – no tuna or tuna processed to the point where a DNA test can’t find any tuna DNA – do you want to eat this sandwich?
