Economic Importance for Humans: Negative
Current research is beginning to show that some tuna consumed by humans may exceed the Food and Drug Administration's original action level of 0.5 ppm mercury. Tuna marketed in stores as white tuna, such as albacore, contains twice as much mercury as skipjack tuna, which is typically marketed as light or chunk light tuna. This is not a major health issue right now, but it may be wise to perform further research on this inorganic metal contaminant in tuna.
