(Nov. 4) SAN DIEGO — So far, this has not been a good year for SureBeam. And the worst may be yet to come.

The company, which was recently de-listed from the Nasdaq stock exchange, warned its investors that it might have to file for bankruptcy if it is unable to secure additional funds.

The company has secured $5 million in equity financing but said in a news release that being de-listed could hurt its ability to raise additional money by selling stock.

In addition, the company — which manufactures electron beam technology that destroys bacteria on food — has come under investigation by the U.S. Securities and Exchange Commission for failing to file its financial reports for the quarter ended June 30. It was this failure that also led to the de-listing.

SureBeam could not be reached for comment.

What this will mean for the irradiation industry remains to be seen. The U.S. Department of Agriculture recently approved irradiation for sweet potatoes, and companies such as Hawaii Pride Inc., Keaau, are already beginning to ship them to the mainland.

Eric Weinert, senior vice president of sales and marketing for Hawaii Pride, said that even if Surebeam goes under, he doesn’t think it will affect the irradiated fruit and vegetable business.

“The technology does what it’s intended to do,” he said. “Because it works it’s going to continue regardless of whether SureBeam is a player in that industry or not.”

Hawaii Pride has used SureBeam’s electron beam process to treat papayas and now sweet potatoes. Weinert said the company will continue with other items and is currently waiting on the USDA to approve the technology for use on bananas.

Weinert said that SureBeam’s problems won’t change what people think about irradiation.

“Major retailers across the country are handling irradiated fruits from Hawaii,” he said. “That should be evidence that the system works. If (Surebeam) runs into further difficulties, it should not be interpreted as a failure of the system.”
