Irradiation plant should help farmers

The issue: A facility for treatment of papayas and other fruits with X-rays is opening on the Big Island.

Our view: The plant could lead to increased sales of island fruits on the mainland and in Japan.

THE dedication of an irradiation facility at Keaau in the Puna district of the Big Island marks the beginning of a new era in the production of papayas and other fruits in Hawaii. It means that a more satisfactory method of eliminating fruit flies and other pests is in operation, carrying with it the potential of expanded markets in the mainland and Japan.

Fruit fly infestation has plagued Hawaii farmers for decades, making it difficult to market their fruits beyond the islands. Bathing the fruit in hot water or vapor has been used to kill the insect larvae but those methods affect the taste.

Nuclear irradiation was proposed back in the 1980s. It would have produced more satisfactory results, but a scare campaign claiming that the fruit would be radioactive discouraged growers who feared consumer resistance.

Although an initiative aimed at blocking the establishment of a nuclear irradiation plant on safety grounds failed in 1998, the plant has never been built. However, the state has been helping growers ship fruit to a cobalt irradiator near Chicago since 1995.

Now a facility using X-rays rather than cobalt to kill the insect larvae is being opened. In addition to papayas, the plant will treat exotic fruits such as rambutan and lychee that are now being grown on the Big Island.

As a spokesman for the manufacturer, Titan Corp., noted, X-rays can be used to treat fruit when it's ripe. "It's more nutritious," he said. "It isn't being steamed for four hours, killing all those vitamins."

Besides preserving the fruit's taste, the X-ray treatment doubles or triples its shelf life, another important benefit. And it avoids the concerns surrounding nuclear materials. The process has been compared to an airport X-ray machine or a television set.

The company behind the plant is called Hawaii Pride LLC. Its owners, two local businessmen, say they hope to process up to 20 million pounds of fruit a year.
The Keaau facility is the first in the nation using X-rays to treat fruit. But Titan Corp. has opened an X-ray plant to treat meat in Sioux City, Iowa.
With the fruit fly problem solved, Hawaii's fruit growers could see a major expansion of production in a few years.
