Claims of Mercury Contamination of Soda
In response to allegations of two mercury poisoning incidents in China, Cardno ChemRisk was asked by a multi-national beverage manufacturer to determine whether their bottling facility was the source of the mercury. After reviewing the bottling process, Cardno ChemRisk scientists established and carried out a sampling campaign at the facility. The levels of mercury were compared to local ambient levels of mercury and relevant regulatory levels. We found below background levels of mercury throughout the facility, which indicated that the bottling facility could not have been the source of the mercury, nor could it have caused mercury poisoning in the consumers. Our results were later confirmed as authorities found deliberate consumer contamination of the product.
