Small toys sold through vending machines did not meet safety standards and some were dangerous, officials warned yesterday. Three of them - a doll key chain, toy doll with sucker and inflatable doll key chain - were small enough to be swallowed and were being recalled. 'We've ordered a selling suspension on the toys while traders are required to recall them from market or consumers,' said a spokesman from the Customs and Excise Department's trading standard investigation bureau. The spokesman said parents should pay close attention to the toys their children played with. 'The doll in the key chain can be easily detached by children. Since the parts are very small, the possibility of a choking hazard is very high. 'And we found that the toys, mostly sold at around $5 and $10, are easily available to children as they can afford to buy them from the vending machines themselves,' he said. The machines are found in smaller shopping centres and some housing estates. The department was considering prosecuting the importers and wholesaler who supplied the dangerous toys. The maximum penalty is a fine of $100,000 and one year's imprisonment. Written warnings were issued over the other 19 substandard toys: an inflatable doll, toy parachutist, inflatable ring, magic block, plastic assembled robot, plastic assembled fighter, assembled robot, Gundam, vanguard sonic, Chinese chess key chain, bottle key chain, toy car, toy tank, toy plane, stamp chop, chess, super B-Daman, super B-Daman basic and bouncing ball. The listed toys, mostly made on the mainland and without brand names, were also found to have violated the Toys and Children's Products Safety Ordinance by failing to have age warnings, identification markings or labelling. Ten of the toys were found by the department's random spot checks while 12 others were referred by the Consumer Council. The investigation involved 16 retailers and 12 importers and wholesalers. Written warnings will be served on all retailers and nine importers and wholesalers.
