Shark oil capsules contaminated with PCBS
Five brands of shark oil capsules available over-the-counter internationally have been found to contain high levels of polychlorinated biphenyls (PCBs), according to a report Jan. 20 in Reuters Health. The Hong Kong Consumer Council named the brands as Squalene from Canada, Purity Natural Squalene Shark Liver Oil from Australia, Squalene 500 from the United States, Natural Boddi Super Squalene from the United States, and SQ from Canada. SQ had the highest levels-312 picograms per maximum daily dosage, which is 1.3 times the tolerable daily limit of 240 picograms established by the World Health Organization (WHO). Natural Boddi Super Squalene contained the lowest amount at 152 picograms and was under WHO’s limit. [Reuters Health, Jan. 20, 2000]
