Equine Stables: Stopping Spread Between Horses
Stable outbreaks spread through shared water buckets, tack, grooming kits and people far more than through air. Strangles, equine herpesvirus and dermatophyte spores all persist on stall surfaces and wood. The controls are isolation of new arrivals, dedicated equipment, and cleaning that removes organic matter before any disinfectant goes on.
Main pathogen pressures in stables
Streptococcus equi subsp. equi, the cause of strangles, spreads by direct contact and through shared troughs, buckets and handlers, and recovered horses can carry it in the guttural pouches for months. Equine herpesvirus 1 moves with nasal secretions at shows and on horse trailers. Ringworm fungi (Trichophyton and Microsporum) shed spores that survive for long periods in wood, bedding and tack. Each needs a different emphasis: carrier screening for strangles, movement control for EHV-1, and surface and equipment hygiene for dermatophytes.
Surfaces that resist disinfection
Unsealed wood, rubber mats with manure in the seams, and porous concrete hold organic soil that consumes oxidizers before they reach microbes. Stall cleandown means removing all bedding, scraping, washing with detergent, rinsing, letting surfaces drain, then applying disinfectant for the full label contact time. Tack, grooming brushes and rugs need their own routine and ideally one set per horse. Water troughs are a shared point of contact: empty, scrub and refill rather than topping up.
Flies, mites and stored bedding
Stable flies and house flies breed in wet bedding and manure heaps and bite or irritate horses. Manure removal frequency, heap placement away from stalls, and larval control in breeding sites reduce populations more than adult sprays. Stored hay and bedding attract stored-product mites and molds. Treat perimeters, manure storage and empty stalls as the targets for premise products; nothing in this range is applied to horses. Keep treated stalls empty until surfaces are dry.
Key facts
- Strangles carriers can shed S. equi intermittently from the guttural pouches after clinical recovery, so screening before release from isolation is recommended (Boyle et al. 2018, J Vet Intern Med 32:633).
- The AAEP recommends isolating new or returning horses and using dedicated equipment and handlers for isolated animals (AAEP Biosecurity Guidelines).
- Organic matter reduces the activity of most disinfectants, so visible soil must be removed first (WOAH Terrestrial Code, ch. 4.14).
- Dermatophyte spores remain viable in the environment for many months, which is why fomite control matters in outbreaks (Moriello et al. 2017, Vet Dermatol 28:266, WAVD clinical consensus guidelines).
How our delivery technology applies
Two delivery problems recur in stables: oxidizers are spent on organic soil, and fly larvicides do not reach larvae deep in manure. Vetpure Disinfectant delivers chlorine dioxide as a stabilized, nano-encapsulated powder that dissolves to at least 98% purity, giving a consistent working solution for troughs, walls and equipment. For fly breeding sites, nematode-based Larva BioControl targets larvae in moist substrate, with premise use pending label amendment.
