The U.S. Public Interest Research Group Education Fund has asked Des Moines-based distributor Bulls I Toy LLC and Target stores to pull certain fidget spinners from the market because of tests that found lead levels that could harm children. The Des Moines company responded that the item is clearly labeled for use by people age 14 and older and therefore is legal under federal laws meant to make sure toys are safe. Lead poisoning can lead to development issues, especially for children under 6. Bulls I Toy representative Timothy Nolan asked the organization to retract its complaint because no laws were broken. Mark Morgenstein, a spokesman for PIRG, a consumer group formed decades ago by Ralph Nader, said his organization continues to push for the recall because fidget spinners — which have been hugely popular in recent months — clearly are a toy that could be used by young children. Morgenstein said PIRG volunteers and employees found the item on Target stores as recently as Thursday night, but it appeared to have been removed from at least some of Target’s online offerings.
