Elements of Production — Biosecurity for Equine Facilities

Biosecurity

A set of practical steps to reduce the chance that disease-causing organisms enter, spread, or leave a horse facility.

Biological Agent

Anything living (or derived from living organisms) that can cause disease or contribute to its spread.

Agent (in biosecurity context)

The pathogen responsible for a disease.

Reservoir/Source

Where the pathogen lives, such as a sick horse, carrier horse, or contaminated environment.

Route of Exit

The method by which the pathogen leaves the host, e.g., nasal secretions, feces.

Mode of Transmission

How the pathogen is transmitted to a new host, e.g., direct contact, droplets.

Route of Entry

The way the pathogen enters a new host, e.g., through the nose or mouth.

Susceptible Host

A host that is vulnerable to infection due to factors like vaccination status or immune suppression.

Fomites

Inanimate objects that can carry infectious material from one horse to another.

Quarantine

Separating apparently healthy but potentially exposed horses for monitoring to prevent disease spread.

Isolation

Separating known or suspected sick horses from healthy horses to prevent further spread.

Pests/Vectors

Living carriers, such as insects, that can transmit pathogens from infected to healthy horses.

High-risk activities

Actions that increase the likelihood of spreading disease, such as horse movement and shared equipment.

Controlled Traffic Flow

Organizing movement in a facility to reduce contamination between clean and dirty areas.

Eradication

The process of eliminating the source of infection or pest populations that support disease spread.

Integrated Pest Management

A comprehensive approach using multiple strategies to reduce pest populations, not just pesticide application.

Cross-site Contamination

The transfer of pathogens from one location to another, often by people or equipment.

Personal Protective Equipment (PPE)

Items like gloves and masks used to protect against contamination during animal care.

High-touch surfaces

Commonly contacted areas that can harbor pathogens, such as door latches and shared tools.

Vaccination Programs

Strategies to reduce susceptibility to disease and often mitigate the severity of symptoms if infection does occur.

Contaminated Equipment

Tools that have come into contact with pathogens, requiring thorough cleaning and disinfection.

Ventilation and Stocking Density

The management of airflow and animal density in a facility, crucial for preventing respiratory disease spread.

Cleaning and Disinfection

The process of removing organic material followed by the application of a disinfectant to kill pathogens.

Outerwear and Gear Cleanliness

Maintaining clean clothing and equipment to prevent contamination when entering animal areas.

Monitoring and Daily Health Checks

Regular observation and assessment of horses, particularly new or returning ones, for signs of illness.

Behavioural Compliance

The adherence to recommended guidelines and protocols by facility staff and visitors to ensure biosecurity.
