Does Grizzly test their salmon oil for heavy metals and PCBs?

Grizzly Salmon oil does not contain measurable amounts of heavy metals. Grizzly Salmon oil is tested by The National Food Laboratory, Inc. The mercury level is below the MDL (Method Detection Limit), which is 0.020 ppm. That means that the level is so low, that it cannot be measured. Grizzly Salmon oil is also tested for PCB's and related chemicals; none of them can be detected.
