One-by-one Caught Albacore, Yellowfin, & Skipjack Tuna Mercury Levels are well below U.S. and International food safety standards. American Tuna Inc., creators of Pole & Line, harvests tuna near the surface of the ocean using the low impact and time-tested “one-by-one” methods. Younger tuna are naturally low in mercury. From an overall nutritional standpoint, tuna is more diverse in its nutrient content than many people would suspect. It is a source of vitamin B3 (niacin), B1 (thiamine) and B6 (pyridoxine) as well as the minerals phosphorus, potassium, and magnesium. Tuna is a good source of protein and also a valuable source of the omega-3 fatty acids EPA and DHA, as well as the antioxidant mineral selenium. The FDA has established a safe mercury level in tuna at or below 1.0 (one) part per million (ppm). The international standard is even more rigorous at 0.5 (one-half) ppm. Our tuna are tested by an independent lab to ensure it is well below these standards. Testing has confirmed mercury levels are <0.3 ppm in all our species. American Tuna Inc.’s albacore are tested both at a fishery and finished product level. The American Albacore Fishing Association (AAFA) also tests albacore catches annually for mercury content – the Pole & Line brand sources all of their albacore tuna from AAFA.
