TRENTON, N.J. — The popular but dangerous toy Aqua Dots was recalled, but the fliers advertising it apparently were not.

A Toys “R” Us flier distributed in some Sunday newspapers contains an ad for Aqua Dots, the popular toy beads yanked from U.S. store shelves nearly three weeks ago because they are coated in a chemical that can turn into the so-called date-rape drug when swallowed.

Retailer Target boasted a $13 price tag for Aqua Dots in its Friday circular.

“These circulars were printed and in distribution before the recall,” Kathleen Waugh, a spokeswoman for Toys “R” Us Inc. said Sunday. “Absolutely, Aqua Dots are not available or for sale.”

Brie Heath, a spokeswoman for Minneapolis-based Target, said its circular was distributed to customers in the 47 states where Target has stores, including Washington.

Target ran an advertisement in the front section of newspapers in most major markets stating that Aqua Dots were no longer available because of the recall, Heath said.

Though anticipated to be among the holiday’s biggest-selling toys, Aqua Dots were recalled in the United States on Nov. 7 after tests showed they are coated with an industrial chemical that, when ingested, metabolizes into the date-rape drug gamma hydroxy butyrate.

The bead-like toy could cause breathing problems, loss of consciousness, seizures, drowsiness, coma and death if ingested. Nine children in the United States and three children in Australia have become sick.

Waugh said ads for the dangerous toy could continue to show up in newspapers for another week or two because those circulars also are printed and distributed far in advance.
