Horseracing Integrity and Safety Authority

Created to implement national, uniform safety and integrity rules backed by science and applied consistently across Thoroughbred racing.

We all have a role to play in horse safety. We recently hosted a webinar on what owners and trainers can do to protect their horses from exercise-associated sudden death. Watch the replay here 👉 https://t.co/6kTmqQeYWs.

@jockeyclub Congrats, @1000Naj! 🎉

[Horseracing Integrity and Safety Authority @hisa_us]

With the help of researchers like Dr. Cris Navas of @pennvet's New Bolton Center, we're working to significantly reduce exercise-associated sudden death in racehorses. As technology improves, sudden death becomes more preventable.

I was pleased to visit @BelmontPark1905 yesterday and have constructive conversations with everyone there. Horse racing is stronger when we all work together towards a common goal, and I'm thankful for Belmont's commitment to safety and integrity in racing.

[Horseracing Integrity and Safety Authority @hisa_us]

Yesterday, HISA staff traveled to the recently reopened @BelmontPark1905 as part of our nationwide listening tour.

Hearing directly from our stakeholders helps us continue building a safer, stronger future for racing together.

A Covered Horse doesn't have to be entered in a race to be tested. Out-of-Competition Testing allows HIWU to conduct testing beyond race day as part of its nationwide efforts to protect the integrity of the sport and promote fair competition.

Have you listened to your horse's #heart today? 🩺

A quick listen to your horse's heartbeat can provide important clues about their health and help alert you to signs of distress, possibly including #AtrialFibrillation. Dr. Cristobal Navas de Solis explains.

Last Friday, @BelmontPark1905, one of the most iconic venues in horse racing, reopened its doors, with a fully remodeled grandstand, four brand new track surfaces and a fueling station for jockeys to support their #nutrition needs.

Welcome back, Belmont!

Before administering a medication or substance to a Covered Horse, check HIWU's Substance Lookup Tool. The tool enables users to search substances and see their Banned or Controlled status under HISA's ADMC Program. Visit https://t.co/U2tmLVYCrF or the HIWU mobile app today.

[Horseracing Integrity and Safety Authority @hisa_us]

Good nutrition and hydration habits are essential for jockeys during racing. We partnered with @TheNYRA to add a fueling station at @Saratoga1863 this summer to ensure jockeys there had everything they needed to perform at their best.

Do safety rates differ between claiming, allowance and stakes races❓

HISA's Q2 Metrics Report analyzes racing-related fatality rates by race type. As more data comes in, we'll be able to determine whether safety outcomes vary across different levels.📊

With the help of researchers like Dr. Cristobal Navas de Solis of @Penn's New Bolton Center, we're working to uncover insights into EASD. We're focused on preventing sudden death in racehorses and making racing safer for horses and their riders.

#AFib #EASD #Heart

[Horseracing Integrity and Safety Authority @hisa_us]

New in our Q2 Metrics Report: racing-related fatality rates are now reported by surface type.

September is National Atrial Fibrillation Awareness Month! ❤️

AFib in Thoroughbred horses is a leading cause of exercise-associated sudden death.

Throughout the month, we'll be sharing special content on AFib prevention and what you can do to help. Stay tuned!
