Veterinary Production Biosecurity: Preventing and Controlling Infectious Disease Spread

Biosecurity

A set of practical steps to reduce the chance that a disease-causing organism enters, spreads, or leaves a site.

Biological agent

Anything living (or biologically derived) that can cause disease.

Chain of infection

A simple model that illustrates how disease spreads via source, exit route, transmission route, entry route, and susceptible host.

Fomites

Inanimate objects that can carry pathogens and facilitate disease transmission.

Transmission route

The mechanism that moves an agent from source to host.

Direct contact

Transmission method involving physical interaction between animals.

Indirect contact

Transmission method involving fomite transfer of pathogens.

Fecal–oral

Transmission method where pathogens spread through contaminated feces.

Aerosol

Transmission method where pathogens spread through airborne droplets.

Vector-borne

Transmission method where pathogens are carried by living organisms like insects.

Quarantine

Temporary separation of animals that may carry a disease from those that are presumed disease-free.

Eradication

The complete removal of a specific pest or pathogen from a population.

PPE (Personal Protective Equipment)

Gear worn to minimize exposure to hazards that can cause injury or illness.

Cleaning

The process of removing organic material to reduce contamination.

Disinfection

The use of chemical or physical methods to inactivate or destroy pathogens.

Cross-site contamination

The transfer of pathogens from one site to another due to movement of people, equipment, or vehicles.

Surveillance

Routine monitoring and reporting of animal health status to detect outbreaks early.

Bio-exclusion

Practices aimed at keeping disease out of a facility.

Bio-management

Practices designed to reduce disease spread within a site.

Bio-containment

Measures taken to prevent the spread of disease once it is introduced into a facility.

Isolation

Separation of sick animals from healthy ones to prevent disease spread.

Integrated pest management (IPM)

A comprehensive approach to controlling pests that includes multiple strategies.

Traffic control

Management of movement of animals, people, and equipment to prevent disease spread.

Sanitation

The process of maintaining a clean environment to reduce the risk of disease.

Health management

Strategies employed to reduce disease susceptibility through vaccination, nutrition, and stress reduction.

High-density housing

Crowded living conditions that can increase stress and reduce immunity in animals.

Versioning

The practice of managing and enforcing rules regarding reused materials and equipment in biosecurity settings.

Document and communicate

Keep accurate records of health cases and movements to ensure effective communication during outbreaks.
