Biosecurity: Bio-exclusion and Bio-containment

Question 1

Define bioexclusion

Answer 1

Activities to reduce the RISK of introduction, to a population, of an external infectious agent

Question 2

Define Biocontainment

Answer 2

Activities to reduce the SOURCE and spread of an infectious agent WITHIN a population

Question 3

What is HAACP

Answer 3

Hazard Analysis and Critical Control Points. It is a systematic, preventive approach to food safety and biosecurity that identifies, evaluates, and controls hazards in production processes.

Question 4

Control of any non-ubiquitous infectious agent should start with a bio-_______ risk assessment

Answer 4

Bioexclusion

Question 5

Is bioexclusion or biocontainment more likely disease specific

Answer 5

Biocontaintment

Question 6

3 key concepts of Bio-exclusion risk assessment

Answer 6

1. Assess a farm to determine the probability of introducing infectious agents (may help to know the farm disease status)
2. Prioritise the highest risk activities (this is a discussion with the farmer)
3. Suggest risk reduction/mitigation strategies to reduce probability of disease introduction

Question 7

4 helpful principals when planning bio-containtment

Answer 7

Source and spread
Challenge and immunity
Single agent and multi-agent infectious disease
Environmental organisms vs specifically host adapted
