Every week, the TDN posts a round-up of the relevant Horseracing Integrity and Safety Act (HISA) related rulings from around the country.The following rulings were reported on HISA's “rulings” portal and through the Horseracing Integrity and Welfare Unit's (HIWU) “pending” and “resolved” cases portals.Among this week's rulings, trainer Juan Munoz Cano has been suspended a combined 12 years and a combined $150,000 (including arbitration costs) for a series of clenbuterol positives spanning the end of last year and earlier this year, according to a final decision by an arbitral body whose ruling can be read here.The ban (a consecutive series of six, two-year suspensions) begins Oct. 7.Though the bronchodilator clenbuterol is classified by HISA as a banned substance, it is permitted for use for a maximum 30 days (within a six-month period) if accompanied with a valid veterinary prescription. Following administration, the horse in question is placed on the vets' list and unable to work or race until it tests clear.The separate cases are a mixture of post-race tests and out-of-competition tests involving six different horses.According to Equibase, Cano has been training since 2020, amassing 129 wins from 936 starts. His most successful year was in 2023, when he collected over $1.6 million in prize money from 32 victories.Also this week, trainer Eusobio Juarez has been suspended a year and fined a combined $18,000 (including arbitration costs) for possession of Diisopropylamine, a banned substance, on Jan. 29. The suspension beings Oct. 8.Diisopropylamine is a banned vasodilator, meaning it can widen the blood vessels and thereby improve blood flow. Diisopropylamine is also found in several everyday items like tobacco and beauty products, as well as hand sanitizer.Resolved ADMC ViolationsDate: 10/07/2025Licensee: Karyn Wittek, trainerPenalty: A written Reprimand (per 9/26/23 HISA Guidance).
