In the study, a total of 42 samples (including white or albacore tuna and light or skipjack tuna) were collected and mercury levels were measured by an independent lab. The results found that white tuna had 0.217 to 0.774 parts per million (ppm) of mercury, averaging 0.427 ppm. Light tuna had much lower mercury levels; 0.018 to 0.176 ppm, with an average of 0.071 ppm. None of the samples exceeded the Food and Drug Administrations mercury limit of 1ppm. However, Consumer Reports based its recommendation on the Environmental Protection Agency's reference dose (RfD) for mercury. This reference dose is the recommended limit for daily intake of mercury throughout an individual's lifetime.
Consumer Reports is recommending that at-risk populations (pregnant women and young children) avoid going over this limit so they should not consume more than 2.5 ounces of white (albacore) tuna or 5 ounces of light (skipjack) tuna a day is unsafe for at-risk populations.

All this information can make decision-making about seafood very complicated and you must seek out the best information and make your own choices. Here is a good news article from the medical community from WebMD Health News and a website from the American Heart Association that gives some additional information that you might find useful.
