We regularly test our wild salmon oil for heavy metals and PCBs. In all the years of producing our own oil in Alaska, we haven’t seen any analysis with measurable contents of mercury, cadmium or lead. PCBs can only be detected by the most sophisticated lab methods, and when tested, occur in extremely low amounts — far less than allowable in human foods. In many ways, using only wild caught salmon from Alaska makes testing a little bit of a formality, unlike farmed salmon oils, which usually test positive for measurable amounts of everything. Here are the testing labs we use in the USA:

Eurofins Scientific Inc., Petaluma, CA
The National Food Laboratory, Inc., Livermore, CA
New Jersey Feed Laboratory, Inc., Trenton, NJ
