McDonald's and the U.S. Consumer Product Safety Commission announced an exchange program on November 10, 1986, for LEGO Building Sets distributed at McDonald's restaurants between October 31 and November 7. The sets were recalled because they contain small parts that could pose a choking hazard to children under three years old, though no incidents had been reported. The LEGO Building Sets have solid-colored borders and a warning label indicating they contain small parts and are not intended for children younger than three.
Customers with children under three who received LEGO Building Sets during the promotional period should exchange them for DUPLO Building Sets, which are designed for younger children and do not contain small parts. For further information, consumers can contact McDonald's Customer Relations Department at (312) 575-6198 or the CPSC toll-free hotline at 800-638-CPSC, with a teletypewriter number for the hearing impaired at (301) 595-7054.
