Chip Implants Linked to Animal Tumors

"At the time we reviewed this, I don't remember seeing anything like that," he said of animal studies linking microchips to cancer. A literature search "didn't turn up anything that would be of concern."

In general, Watson said, companies are expected to provide safety-and-effectiveness data during the approval process, "even if it's adverse information."

Watson added: "The few articles from the literature that did discuss adverse tissue reactions similar to those in the articles you provided, describe the responses as foreign body reactions that are typical of other implantable devices. The balance of the data provided in the submission supported approval of the device."

Another implantable device could be a pacemaker, and indeed, tumors have in some cases attached to foreign bodies inside humans. But Dr. Neil Lipman, director of the Research Animal Resource Center at Memorial Sloan-Kettering, said it's not the same. The microchip isn't like a pacemaker that's vital to keeping someone alive, he added, "so at this stage, the payoff doesn't justify the risks."

Silverman, VeriChip Corp.'s chief executive, disagreed. "Each month pet microchips reunite over 8,000 dogs and cats with their owners," he said. "We believe the VeriMed Patient Identification System will provide similar positive benefits for at-risk patients who are unable to communicate for themselves in an emergency."

And what of former HHS secretary Thompson?

When asked what role, if any, he played in VeriChip's approval, Thompson replied: "I had nothing to do with it. And if you look back at my record, you will find that there has never been any improprieties whatsoever."

FDA's Watson said: "I have no recollection of him being involved in it at all." VeriChip Corp. declined comment.

Thompson vigorously campaigned for electronic medical records and healthcare technology both as governor of Wisconsin and at HHS. While in President Bush's Cabinet, he formed a "medical innovation" task force that worked to partner FDA with companies developing medical information technologies.

At a "Medical Innovation Summit" on Oct. 20, 2004, Lester Crawford, the FDA's acting commissioner, thanked the secretary for getting the agency "deeply involved in the use of new information technology to help prevent medication error." One notable example he cited: "the implantable chips and scanners of the VeriChip system our agency approved last week."

After leaving the Cabinet and joining the company board, Thompson received options on 166,667 shares of VeriChip Corp. stock, and options on an additional 100,000 shares of stock from its parent company, Applied Digital Solutions, according to SEC records. He also received $40,000 in cash in 2005 and again in 2006, the filings show.

The Project on Government Oversight called Thompson's actions "unacceptable" even though they did not violate what the independent watchdog group calls weak conflict-of-interest laws.

"A decade ago, people would be embarrassed to cash in on their government connections. But now it's like the Wild West," said the group's executive director, Danielle Brian.

Thompson is a partner at Akin Gump Strauss Hauer & Feld LLP, a Washington law firm that was paid $1.2 million for legal services it provided the chip maker in 2005 and 2006, according to SEC filings.

He stepped down as a VeriChip Corp. director in March to seek the GOP presidential nomination, and records show that the company gave his campaign $7,400 before he bowed out of the race in August.

In a TV interview while still on the board, Thompson was explaining the benefits _ and the ease _ of being chipped when an interviewer interrupted:

"I'm sorry, sir. Did you just say you would get one implanted in your arm?"

"Absolutely," Thompson replied. "Without a doubt."

"No concerns at all?"

"No."

But to date, Thompson has yet to be chipped himself.
