CA AB2615

Codifies existing California Horse Racing Board regulations requiring mandatory postmortem examinations for horses that suffer fatal injuries on racetracks, die, or are euthanized within the board's jurisdiction at a contracted diagnostic laboratory.

Authorizes collection of test samples from horse carcasses to screen for foreign substances, their metabolites, and natural substances at abnormal levels, with samples obtained before euthanasia when practical.

Assigns transportation costs to the racing association or racetrack/training center where death occurred, while providing standard necropsy services and laboratory testing at no charge to owners; additional examinations requested by owners or trainers are their responsibility.

Requires postmortem examination requests to be filed with the official veterinarian within one hour of death using a board-approved form, with the diagnostic laboratory filing written reports to the board's executive director, equine medical director, and official veterinarian upon completion.

Makes acceptance of postmortem examination procedures a mandatory requirement for owners and trainers to maintain their occupational licenses, with violations constituting crimes under the Horse Racing Law.
