A greyhound trainer, suspended after 12 dogs in his care tested positive for cocaine, has a history of citations for drug violations in racing dogs, First Coast News has learned.

Charles McClellan, a greyhound trainer whose dogs race at Bestbet Orange Park track, has problems dating back to 1992, according to documents obtained from state regulators.

We first told you about the suspension of Charles McClellan last week. McClellan was an independent contractor at Bestbet until last month.

STORY: 12 greyhounds test positive for cocaine at Bestbet race track

First Coast News obtained records from the state Department of Business and Professional Regulation. 12 dogs in McClellan's care tested positive for cocaine, one multiple times, for a total of 18 incidents in four months.

McClellan's license was suspended on June 9 pending an administrative hearing in August. On Friday, the state confirmed to First Coast News that Bestbet wasn't notified of the test results until McClellan's suspension in June.

According to the state, "there is no statutory requirement that the facility be notified."

The state requires the winner of each greyhound race, as well as another randomly chosen dog, to be drug tested after races. Urine tests conducted by the University of Florida College on Medicine Racing Laboratory came back positive for Benzoylecgonine (BZE) -- a metabolite of cocaine.

The dogs McClellan was training are housed at a kennel owned by Steve Sarras, including a female Flicka, who tested positive for cocaine six times over four months, according to state records. Sarras acknowledged the positive tests, however in a statement to First Coast News, Sarras says the amounts of BZE were minuscule and could be the result of environmental contamination.

"All dogs that tested positive WOULD NOT have failed any federally mandated human drug test. Horse racing has also started to use these federal drug testing guidelines. A commercial airline pilot or a truck driver would have to have tested at concentrations 4 to 14 times higher than the greyhound’s to even warrant a second test to confirm a positive or failed drug test .... Quite simply it is propaganda against the greyhound industry," Sarras said.

"This is the largest greyhound drug case in American history," says Carey Theil, Executive Director of GREY2K USA in Arlington, Mass., a non-profit that opposes greyhound racing and monitors dog tracks around the country. "This is staggering."

Since this story broke, First Coast News has learned that McClellan had issues with state regulators in multiple counties before the time he even came to Bestbet.

The documents date back to 1992 when McClellan received a warning letter from the state about "purse redistribution" in Palm Beach County.

The first drug case came in June 2011, when in "GS Max", a McClellan trained dog, tested positive for a drug called "procaine", described as a "local anesthetic", after a race in Volusia County, according to state records. He was fined $100.

In March 2012, a McClellan trained dog named "Barts Misty Morn" tested positive for a banned "narcotic analgesic", according to the UF testing lab. That incident happened in Brevard County. The state later ordered that his license be revoked and he be fined $5,000 after this incident, but that was then reduced to a 60-day suspension and a $1,000 fine, according to state licensing records.

In 2013, McClellan received an official warning notice from the state for "failure to report within 18 hours the death of a racing animal for which you are responsible." The death of a dog named "AMF Pennywise" was reported some three weeks too late, according to state records.

In our previous story, Bestbet Orange Park issued a statement, which in part said they "maintain a zero-tolerance policy for any trainer or staff member that does anything which puts one of the dog’s health at risk."

In a written statement Steve Sarras acknowledged that "17 positive tests involve 12 dogs in (his) kennel."

Sarras calls the positive tests a contamination.

"This is an issue of innocent environmental contamination," said Sarras. "No dogs were put in harm's way or have exhibited any health issues. My dogs have been tested at a disproportionately higher level than other kennels in Jacksonville since the begin of political sessions."

Sarras went on to say that "all dogs that tested positive would NOT have failed any federally mandated human drug test."
