Dear Thoroughbred racing participants,

HISA’s most important mission is to protect the health and wellbeing of the horses participating in Thoroughbred racing. Over the past few months, the challenges of that mission – and the critical importance of it – have never been more apparent.

The events at Churchill Downs, Laurel Park and Saratoga Race Course this spring and summer were a sobering reminder that we must further prioritize creating a culture of safety and an ecosystem of care that takes into account all factors contributing to equine fatalities. And it is the responsibility of all racing participants to do their part.

HISA’s investigation into the circumstances surrounding equine fatalities at Churchill Downs earlier this year did not identify any singular explanation for the fatalities, despite extensive investigation and analysis of the track surface, veterinary records, necropsies and whether any rule violations occurred. The absence of a singular explanation underscores the urgent need for further action and analysis to mitigate risk stemming from several factors potentially contributing to equine fatalities. HISA’s full report on the findings was released publicly last week and can be found here.

HISA’s strategic recommendations and next steps moving forward – also announced last week – include the following:

  • A sophisticated data analysis effort to explore critical questions facing the sport to yield new, actionable insights, made possible by uniform reporting requirements under HISA.
  • The creation of a committee to work toward the study and ultimate introduction of more synthetic surface options in Thoroughbred racing.
  • Improved veterinary screening and diagnostic procedures, including:
    • Making PET scans more accessible to racetracks across the country
    • Conducting a research study to examine the causes of exercise-associated sudden deaths
    • Further use of wearable technology as an injury detection tool
    • An examination of whether there are any other equine fitness tools worthy of investment and deployment

As detailed below, HISA has also formed a new Track Surface Advisory Group comprised of seasoned track superintendents to assist in surface analysis and make recommendations on an ongoing basis.

This moment is and should be a turning point for our sport. It is essential that all corners of the racing world come together to do their part to reduce equine fatalities and protect these magnificent athletes.

HISA is grateful for the work of everyone involved in the sport whose job it is to protect the health and wellbeing of Thoroughbreds. We know that you share in our cause and that together, we can make racing the safest, and best, version of itself.

Yours in racing,

HISA Releases RFP on Furosemide

On Aug. 29, HISA released a request for proposals for research on the administration of furosemide to Thoroughbred racehorses during the 48-hour period before the start of a race.

HIWU Update

From the desk of Ben Mosier, Executive Director, Horseracing Integrity & Welfare Unit:

Entering the final quarter of 2023, HIWU has so far tested more than 30,000 horses and resolved more than 50 cases. As the Breeders’ Cup draws near, preparations by our operations and investigations teams are already under way. This year’s Breeders’ Cup will be the first held under the ADMC Program rules, and we are excited to partner with the Breeders’ Cup and 1/ST to help ensure that the event continues to be held to the highest standards of integrity and safety.

As part of implementing the ADMC Program, HIWU continues to fine-tune processes and educate industry stakeholders to enhance the effectiveness of the Program, facilitate compliance, and promote equine welfare.

As stated earlier, the HIWU executive team recently participated in HISA’s first Town Hall Webinar. We appreciated the opportunity to answer questions about the ADMC Program, which were submitted by a wide range of participants. Questions that we did not have time to address during the webinar have been or will be answered directly to the individuals who submitted them. HIWU also welcomes questions any time via or our mobile app.

Relatedly, HISA and HIWU recently published updated guidance regarding Provisional Suspensions, Controlled Medication Rule Violations, electrolytes, and supplement labels. Any questions regarding this information should be directed to the aforementioned email address or app.

Further, we are excited to have Alan Foreman working with HISA and HIWU as an ombudsman to assist the industry with HISA’s rules. Alan brings tremendous experience to this role, and we at HIWU appreciate his willingness to serve the industry in this capacity. We encourage industry participants to utilize Alan as a fair and objective resource when navigating both the ADMC Program and the Racetrack Safety Program.

The last four months have flown by, and the HIWU team is as energized as ever in fulfilling our mandate to administer Thoroughbred racing’s first national, uniform ADMC program.

Thank you all again for all you do to ensure that we’re moving forward together. 

Lisa Lazarus
