The Horseracing Integrity & Welfare Unit (HIWU) announced today the release of its 2024 Annual Report. The full report is available here. The Annual Report details HIWU’s organization-wide activities as the independent enforcement agency of the Horseracing Integrity and Safety Authority’s (HISA) Anti-Doping and Medication Control (ADMC) Program. Among the highlights are statistics on testing, results management, the adjudication of cases, investigations, and educational efforts. The 2024 Annual Report introduces expanded testing statistics by state and racetrack, including the number of samples collected for each test type. Additionally, it reveals shorter turnaround times for results reporting compared to 2023, showcases the impact of HIWU’s investigative efforts, and reports a consistently low rate of Adverse Analytical Findings for Controlled Medications, demonstrating that the vast majority of Covered Persons are complying with the ADMC Program Rules. “HIWU’s successes in 2024 reflect the dedication of our team and the entire Thoroughbred industry,” said Ben Mosier, executive director for HIWU. “The collaboration between HIWU and industry stakeholders enabled us to build on the ADMC Program’s strong foundation that was established in 2023. HISA’s reported record-low fatality numbers last year indicate that we are fulfilling our mandates to enhance equine safety and welfare and promote the integrity of racing.” All Annual Reports and Quarterly Statistics are archived in the About Us section of the HIWU website at hiwu.org for viewing anytime. About the Horseracing Integrity & Welfare Unit The Horseracing Integrity & Welfare Unit (HIWU) was established in 2022 by Drug Free Sport International to administer the rules and enforcement mechanisms of the Horseracing Integrity and Safety Authority’s (HISA) Anti-Doping and Medication Control (ADMC) Program. The ADMC Program established a centralized testing and results management process that applies uniform penalties for violations efficiently and consistently across all American Thoroughbred racing jurisdictions that HISA governs. As the enforcement agency of the ADMC Program, HIWU oversees all testing processes, including the selection of horses to be tested, training of sample collection personnel, and chain-of-custody procedures. Additionally, HIWU is charged with industry/stakeholder education, laboratory accreditation, results management and adjudication, and investigations. For more information, please visit hiwu.org.

The Horseracing Integrity & Welfare Unit (HIWU) announced today that it has directed the Pennsylvania Equine Toxicology and Research Laboratory (PETRL), a Horseracing Integrity and Safety Authority (HISA) Anti-Doping and Medication Control (ADMC) Program laboratory, to modify its instrumentation and methodology for TCO2 testing to mass spectrometry so that it is consistent with HIWU’s three other Program laboratories. PETRL has already transitioned to this methodology, which is also independently endorsed by the International Federation of Horseracing Authorities. HIWU began its review of PETRL’s procedures in response to a disproportionately high number of reports of elevated TCO2 levels from the laboratory and worked with horsemen’s representatives throughout this process. HIWU first undertook a comprehensive assessment of testing documentation and laboratory processes at PETRL before asking the Kenneth L. Maddy Equine Analytical Laboratory at the University of California Davis to conduct an administration study to compare the findings reported by the Program laboratories. PETRL’s instrument (a clinical blood gas analyzer) and related methodology had been used and accepted as valid by the horse racing industry to regulate TCO2 for years prior to the implementation of the ADMC Program, and HIWU found no evidence of laboratory error or instrument failure by PETRL. However, the data from the administration study indicated that PETRL’s results did not correlate with those of the three other laboratories, which all used an instrument and methodology (mass spectrometry) different from PETRL’s. In response, HIWU has issued a new mandate for mass spectrometry to be adopted as the industry standard for TCO2 analysis confirmation. This method is used to analyze virtually all other substances regulated under the ADMC Program. In the interest of fairness to horsemen, all pending TCO2 cases originating in Pennsylvania have been withdrawn; due to the accelerated degradation of TCO2 samples compared to other analytes, HIWU could not send previously analyzed samples to other Program laboratories to compare the results. For cases that have already been resolved, HISA offered to return purse money, refund fines, notify Equibase to remove the disqualifications, and remove penalty points from the affected trainers’ records. Purse money that has already been distributed by racetracks in relation to these cases will not be affected. “The discovery of inconsistencies in TCO2 testing across Program laboratories and HIWU’s subsequent responsibility to establish harmonization among them represent the benefits of a national ADMC program,” said Ben Mosier, executive director of HIWU. “Unlike under state-based regulatory structures, our Program laboratories are in ongoing communication to discuss and compare methods. This collaboration is what enabled us to identify and resolve discrepancies in TCO2 testing despite the longstanding validity of the methods and instruments being used.” “I commend HIWU for taking action in response to the high rate of TCO2 findings at PETRL and ultimately facilitating the harmonization of TCO2 testing among Pennsylvania and other states,” said Jeffrey A. Matty, Jr., executive director of the Pennsylvania Thoroughbred Horsemen’s Association. “Ben and his team listened to our horsemen’s concerns and were in ongoing communication with us while the laboratory was reviewed. We’re also appreciative of HISA for their decision to offer to withdraw sanctions imposed for cases that have already been resolved. “This process represents an example of how a national, uniform system helps horsemen and how we, HIWU, and HISA can work together for the benefit of the entire industry.” Evaluation of testing at Program laboratories is ongoing to ensure consistency and fairness in results reporting. HIWU has implemented HISA Equine Analytical Laboratory (HEAL) accreditation as of January 1, 2025. HEAL accreditation includes a robust Equine Quality Assurance Scheme sample program. About the Horseracing Integrity and Safety Authority When the Horseracing Integrity and Safety Act was signed into federal law, it charged the Horseracing Integrity and Safety Authority (HISA) with drafting and enforcing uniform safety and integrity rules in Thoroughbred racing in the U.S. Overseen by the Federal Trade Commission (FTC), HISA is implementing, for the first time, a national, uniform set of rules applicable to every Thoroughbred racing participant and racetrack facility. HISA is comprised of two programs: the Racetrack Safety Program, which went into effect on July 1, 2022; and the Anti-Doping and Medication Control (ADMC) Program, which went into effect on May 22, 2023. The Racetrack Safety Program includes operational safety rules and national racetrack accreditation standards that seek to enhance equine welfare and minimize equine and jockey injury. The Program expands veterinary oversight, imposes surface maintenance and testing requirements, enhances jockey safety, regulates riding crop use and implements voided claim rules, among other important measures. The ADMC Program includes a centralized testing and results management process and applies uniform penalties for violations efficiently and consistently across the United States. These rules and enforcement mechanisms are administered by an independent agency, the Horseracing Integrity & Welfare Unit (HIWU), established by Drug Free Sport International (DFSI).

The Horseracing Integrity & Welfare Unit (HIWU) and Horseracing Integrity and Safety Authority (HISA) released today the results of HIWU’s investigation of the University of Kentucky Equine Analytical Chemistry Laboratory (UK-EACL). The full report can be accessed here. The report details the events leading up to the investigation, including UK-EACL’s persistent delays in reporting results, unprofessional staff behavior, and unresponsiveness to HIWU communications. Ultimately, the catalyst for the commencement of the investigation was the discovery by HIWU of intentional misrepresentations that were made about Sample analysis. Key findings of the six-month long investigation include: - UK-EACL’s failure to comply with mandatory testing specifications and instructions, including its standard operating procedures and sample analysis methods. - UK-EACL misrepresented both its ability to test for specific substances, including erythropoietin (EPO), and the completion of analysis for certain substances on specific Samples. - At the direction of UK-EACL Director Dr. Scott Stanley, the laboratory failed to perform confirmatory analysis on 91 Samples whose initial screening showed the potential presence of a Prohibited Substance and therefore required follow-up, instead reporting the Samples as Negative. As a result of these findings, HIWU re-analyzed and reconciled all remaining potentially affected Samples, and HISA has sought repayment from the University of Kentucky for the laboratory’s non-compliant services. “A key component of HIWU’s mandate is to protect the integrity of Thoroughbred racing and resolve potential deficiencies as soon as possible,” said Ben Mosier, HIWU’s executive director. “Through our decision to investigate UK-EACL and consequent discovery of ongoing deceitful activities, we’re proud to have uncovered and halted these unacceptable practices that were unfair to our horsemen and put horses at risk.” “HISA’s and HIWU’s actions to uncover these wrongdoings and quickly remedy them is a testament to how the Anti-Doping and Medication Control (ADMC) Program is enhancing the integrity of our sport and ensuring fairness in competition,” said HISA Chief Executive Officer Lisa Lazarus. “We also thank the University of Kentucky for their partnership and cooperation in the investigation.” To provide further assurance that the other Program Laboratories are in compliance with the ADMC Program requirements, HIWU has bolstered its Negative Sample Exchange Program and is preparing to implement HISA Equine Analytical Laboratory (HEAL) accreditation on January 1, 2025. HEAL accreditation will include enhanced compliance oversight by HIWU and a more robust Equine Quality Assurance Scheme sample program. Currently, in a transitional phase, lab accreditation is handled by the Racing Medication & Testing Consortium. HISA/HIWU were initially required to utilize the services of UK-EACL under the requirements of the Horseracing Integrity and Safety Act. HEAL accreditation will give HIWU a strengthened ability to ensure strict compliance by all Program Laboratories with all ADMC Program requirements.
