Fresh Chilean grapes were being trucked across the country Friday after a two-week absence from store shelves because of a cyanide poisoning scare, industry leaders say.

Consumers may see slightly higher prices on the produce initially, but prices are expected to drop back to pre-scare levels in a couple of weeks when supply catches up with demand, they said.Losses to Chilean exporters and to U.S. fruit importers as a result of the cyanide scare over grapes and other produce are estimated at $240 million, Ronald S. Bown, executive director of the Chilean Exporters Association, said Thursday.

Some of those losses may be offset by a plan being developed by the Chilean government to compensate U.S. importers, wholesalers and retailers as well as Chilean growers and exporters, Bown said.

Officials at the Chilean embassy in Washington did not return telephone calls for comment on the plan.
