How are heavy metals, PCB and dioxins assessed in fish oil?
Direct answer
These substances are analytically tested as contaminants and set against the applicable maximum levels. Missing disclosures do not mean no contaminants are present — they mean nothing was published.
Contaminants enter the product through the raw material origin — not through processing.

Why the raw material decides
Heavy metals, dioxins and PCB come from the environment and accumulate along the food chain. Processing can reduce concentrations, but the initial load determines the effort.
Three test areas
Heavy metals
lead, mercury, cadmium, arsenic
Dioxins and furans
reported as TEQ
PCB
sum of congeners

Reading missing disclosures
If no value is found in reviewed public sources, this is explicitly shown as not publicly disclosed. It is treated neither as zero nor as a defect.
