27th annual survey finds dangerous toys on store shelves November 20, 2012 -- Updated 1926 GMT (0326 HKT) U.S. Public Interest Research Group releases its annual Trouble in Toyland survey It finds risks of choking, strangulation, lacerations and toxic exposure The group says the government's regulations on small toys should be expanded Washington (CNN) -- 'Tis the season to be wary when it comes to buying potentially dangerous toys for children this holiday. Toxic and dangerous toys are right now sitting on store shelves, and a public interest group is warning consumers to beware when purchasing toys for toddlers because of possible safety hazards. The U.S. Public Interest Research Group released its 27th annual Trouble in Toyland survey Tuesday, and the progress report concluded what it has noted in previous years: toy hazards come in a variety of shapes and forms. Children can be injured from small parts that pose choking risks, strangled by cords on pull toys, lacerated by sharp edges, and endangered by exposure to toxic chemicals. Over the years, the organization said, its reports have led to more than 150 recalls and other regulatory actions. This year's list "includes a potentially dangerous magnet toy, a bowling game that is a choking hazard and a key chain rattle that may be harmful to little ears," it said. Researchers visited national toy stores, malls and dollar stores in September, October and November this year to look for potential toxic, choking, strangulation and noise hazards. We should be able to trust that the toys we buy are safe. However, until that's the case, parents need to watch out for common hazards when shopping for toys," said Nasima Hossain, public health advocate for Public Interest Research Group, in a release detailing the report. Among the survey's findings: Lead exposure from toys remains a serious risk to the brains of young children and "can cause permanent mental and developmental impairments." Magnet toys pose problems, especially if the magnets are swallowed. The Consumer Product Safety Commission has estimated there were 1,700 emergency room cases nationwide between 2009 and 2011 involving the ingestion of high-power magnets, nearly three quarters of them in children between 4 and 12. Two toys -- a car driving wheel on a console and a toy guitar -- exceed the recommended limit for continuous exposure to noise above 65 decibels. Researchers say one in five U.S. children will have some degree of hearing loss by the time they reach the age of 12. Several toys contain small parts having what the organization says is improper labeling and "might be mistakenly purchased for children under 3." Choking on small toy parts such as marbles and balloons has resulted in hundreds of deaths over the past two decades. Consumers are urged to examine toys carefully for potential dangers before making a purchase. The U.S. Public Interest Research Group recommends the Consumer Product Safety Commission review its definition of "small part" or "small toy" to include parts and toys that are larger than the current standard but have been shown to pose a choking hazard. It also calls for "vigorous" enforcement of lead limits in toys.
