Section 4.50 - Veterinary Practices(1)Veterinarians under the Authority of the Official Veterinarian. Veterinarians licensed by the Commission and practicing at any location under the jurisdiction of the Commission are under the authority of the official veterinarian and the Stewards. The official veterinarian shall recommend to the Stewards or the Commission the discipline that may be imposed upon a veterinarian who violates the rules.(2)Appropriate Role of Veterinarians. The following limitations apply to drug treatments of horses that are engaged in activities, including training, related to competing in pari-mutuel racing in the jurisdiction: (a) No drug may be administered except in the context of a valid veterinarian-client-patient relationship between an attending veterinarian, the horse owner (who may be represented by the trainer or other agent) and the horse. The owner is not required by 205 CMR 4.50(2) to follow the veterinarian's instructions, but no drug may be administered without a veterinarian having examined the horse and provided the treatment recommendation. Such relationship requires the following: 1. The veterinarian, with the consent of the owner, has accepted responsibility for making medical judgments about the health of the horse;2. The veterinarian has sufficient knowledge of the horse to make a preliminary diagnosis of the medical condition of the horse;3. The veterinarian has performed an examination of the horse and is acquainted with the keeping and care of the horse;4. The veterinarian is available to evaluate and oversee treatment outcomes or has made appropriate arrangements for continuing care and treatment;5. The relationship is maintained by veterinary visits as needed; and6. The veterinary judgments of the veterinarian are independent and are not dictated by the trainer or owner of the horse.(b) No prescription drug may be administered except as prescribed by an attending veterinarian.(c) The trainer and veterinarian are both responsible to ensure compliance with these limitations on drug treatments of horses, except the medical judgment to recommend a drug treatment or to prescribe a drug is the responsibility of the veterinarian and the decision to proceed with a drug treatment that has been so recommended is the responsibility of the horse owner (who may be represented by the trainer or other agent).(3)Treatment Restrictions. (a) Only licensed trainers, licensed owners or their designees shall be permitted to authorize veterinary medical treatment of horses under their care, custody and control at locations under the jurisdiction of the Commission.(b) Except as otherwise provided by 205 CMR 4.50(3), no person other than a veterinarian licensed to practice veterinary medicine in this jurisdiction and licensed by the Commission may administer a prescription or controlled medication, drug, chemical or other substance (including any medication, drug, chemical or other substance by injection) to a horse at any location under the jurisdiction of the Commission.(c)205 CMR 4.50(3)(c) does not apply to the administration of the following substances except in approved quantitative levels, if any, present in post-race samples or as they may interfere with post-race testing: 1. A recognized non-injectable nutritional supplement or other substance approved by the official veterinarian;2. A non-injectable substance on the direction or by prescription of a licensed veterinarian; or3. A non-injectable non-prescription medication or substance.(d) No person shall possess a hypodermic needle, syringe capable of accepting a needle or injectable of any kind on association grounds, unless otherwise approved by the Commission. At any location under the jurisdiction of the Commission, veterinarians may use only a one-time disposable syringe and needle, and shall dispose of both in a manner approved by the Commission. If a person has a medical condition which makes it necessary to have a syringe at any location under the jurisdiction of the Commission, that person may request permission of the Stewards and/or the Commission in writing, furnish a letter from a licensed physician explaining why it is necessary for the person to possess a syringe, and must comply with any conditions and restrictions set by the Stewards and/or the Commission.(e) Practicing veterinarians shall not have contact with an entered horse within 24 hours before the scheduled post time of the race in which the horse is scheduled to compete except for the administration of furosemide under the guidelines set forth in 205 CMR 4.52(6) unless approved by the official veterinarian. Any unauthorized contact may result in the horse being scratched from the race in which it was scheduled to compete and may result in further disciplinary action by the Stewards.(f) Any horse entered for racing must be present on the grounds prior to the scheduled furosemide administration time or one hour prior to first post time whichever is earlier.(4)Veterinarians' Reports. (a) Every veterinarian who treats a racehorse at any location under the jurisdiction of the Commission shall, in writing on the medication report form prescribed by the Commission, report to the official veterinarian or other Commission designee at the racetrack where the horse is entered to run or as otherwise specified by the Commission, the name of the horse treated, any medication, drug, substance or procedure administered or prescribed, the name of the trainer of the horse, the date and time of treatment and any other information requested by the official veterinarian.(b) The medication report form shall be signed by the practicing veterinarian.(c) The medication report form must be filed by the treating veterinarian not later than post time of the race for which the horse is entered. Any such report is confidential and its content shall not be disclosed except in the course of an investigation of a possible violation of the Commission's regulations or in a proceeding before the Stewards or the Commission, or to the trainer or owner of record at the time of treatment.(d) A timely and accurate filing of a medication report form that is consistent with the analytical results of a positive test may be used as a mitigating factor in determining the nature and extent, if any, of a rules violation.Amended by Mass Register Issue 1356, eff. 6/9/2017.
