JUSTIN PRITCHARDLOS ANGELES (AP) â¿¿ Federal regulators failed to pursue recalls after they found cadmium-tainted jewelry on store shelves, despite their vow to keep the toxic trinkets out of children's hands, an Associated Press investigation shows. Officials at the U.S. Consumer Product Safety Commission also have not warned parents about the contaminated items already in their homes. More than two years after the AP revealed that some Chinese factories were substituting cadmium for banned lead, the CPSC still hasn't determined the extent of the contamination. Contaminated jewelry is surely less prevalent in the U.S. than before its widespread presence was first documented. However, rings, bracelets and pendants containing cadmium and marketed for preteen girls were purchased over the last year. The AP and representatives of two consumer groups were able to buy the items in Los Angeles, suburban San Francisco, central Ohio and upstate New York. Despite touting its work as a model of proactive regulation, the agency tasked with protecting Americans from dangerous everyday products often has been reactive â¿¿ or inactive. Take a "children's jewelry sweep" the CPSC conducted at stores nationwide. Testing showed that six different items on shelves â¿¿ including one referred to as a "baby bracelet" â¿¿ were hazardous by the agency's guidelines. Yet the agency neither pursued recalls nor warned the public about the items, records and interviews show. In addition, the CPSC allowed Wal-Mart Stores Inc. and Meijer, a smaller Midwest chain, to pull from shelves jewelry that flunked safety testing without telling parents who had previously purchased such items. And it did not follow through on evidence it developed that cadmium jewelry remains on sale in local shops. Agency staffers have consistently sided with firms that argued their high-cadmium items shouldn't be recalled â¿¿ not because they were safe in the hands of kids, but because they were deemed not to meet the legal definition of a "children's product." Also, the CPSC trusted retailers and jewelry importers to self-police their inventories for cadmium, but did not check whether they had done so for at least a year.
