The New York Post reported today that Usana Health Sciences (NASDAQ: USNA) CFO Gil Fuller doesn't really have a CPA; he just says he has one in SEC filings. This is perhaps the most serious in a series of credentials flaps for Usana that I've listed on BloggingStocks last week. Here's the updated list:

• Denis Waitley, a director at the company, decided not to stand for re-election after investigator Barry Minkow uncovered that the PhD listed in his biography came from a long-defunct diploma mill. He also does not possess a Master's degree, although one was reported in numerous SEC filings.
• Dr. Timothy Wood, Vice President of Research and Development at the company, claimed to have a PhD in biology, but it's actually in forestry, which seems less relevant at a company that makes nutritional supplements.
• Myron Wentz, the company's founder and Chairman, renounced his U.S. citizenship to "move" to the tax haven of Liechtenstein.
• And now, according to the Wall Street Journal, Dr. Ladd McNamara has left the company's medical advisory board after it was discovered that he no longer has a medical license [subscription required]. A Usana spokesman said that McNamara surrendered his license in Georgia in 2004 in response to allegations that he improperly prescribed medication to a family member. He also agreed to a lifetime ban from practicing medicine in Ohio.
• CFO Gil Fuller claims to be a Certified Public Accountant. While it's quite common to let a CPA license lapse, he hasn't been one since 1986. Back then, people were terrified of communism, everyone in Boston hated Bill Buckner and the New Kids on the Block were cool -- OK, no, they weren't. But the point is that being a CPA in 1986 doesn't really mean anything in 2007.

In a few weeks, Usana will be releasing its quarterly earnings. You have to ask yourself: Given that the company 's management can't seem to stop lying about their credentials, why should we believe the earnings numbers they present, or anything else they say?
