No Contaminants Detected

No Contaminants Detected
Contaminants that must be checked for include mercury, arsenic, lead, PCBs, dioxins, mold and bacteria. In reality, some amount will almost always be present, however the evaluation must confirm that none are detectable in the parts per billion or parts per trillion.
Various measurements are used to test for mold and bacteria, however, the producer needs to have the oils and high standards should comply with those standards. Or else the batch should be discarded.
