During this session we will cover:

Training Agenda

1. Unwanted Organisms2. Overview of the Exotic Disease Lifecycle3. Exotic Disease Response

Introduction to EDR 4

Knowledge Checks• Are not designed to Pass or Fail you!• Make sure you have understood what you have

learned before moving on to the next module.• You can refer to your reference material (processes

and procedures) if you need to.• If you haven’t achieved 100% accuracy, I’ll provide

some help before we move on to the next topic.

Introduction to EDR 5

1. Unwanted Organisms Objective

By the end of this topic you will be able to:

• Explain what exotic diseases are, and what causes them, and

• Explain what unwanted organisms are, how they are introduced to NZ and how they are kept out.

Introduction to EDR 6

Scope of EDR TrainingCovers… Does not yet cover…

Exotic disease and exotic pests of animals

Plant pests and disease, unwanted plants, algae etc

Animals include birds, mammals and aquaculture

Marine animals or bees

Disease affecting farmed or working animals and pets

Wild animals

From point of response declaration Ag quarantine and initial investigations

Operational roles Planning, intelligence, logistics, management

Introduction to EDR 7

Something you catch in Hawaii

An animal pest or disease, not already present in NZ, introduced via the import of unwanted organisms, that causes harm to our agricultural sector

What is an Exotic Disease?

NOT

IT IS

Introduction to EDR 8

NZ Export Earnings

(NZ Trade and Enterprise, 2004)

Commodity $$ Millions

Meat 4,629

Dairy 5,683

Wool 731

Total Export Earnings 28,525

Introduction to EDR 9

Bacteria

Unwanted Organisms Causing Disease

Viruses

Other micro-organisms

Introduction to EDR 10

Internal parasites

Unwanted Organisms (Pests)

External parasites

Introduction to EDR 11

Likely Means of Entry to NZ

Imported stock

Prohibited goods

Soil – on vehicles, camping gear, footwear etc

Stowaways – vermin, insects etc

Introduction to EDR 12

Prohibited imports – meats etcSanitary measures applied to imports of animal

productsBorder checks for prohibited importsBorder treatment of risk goodsTesting of imported animalsQuarantine of imported animals

Exotic Disease Prevention

Introduction to EDR 13

2. Overview of the Exotic Disease Lifecycle

ObjectiveBy the end of this topic you will be able to:• explain how diseases can spread and what affects

the speed of spread, and• explain the exotic disease life cycle and give

examples.

Introduction to EDR 14

How Disease Can Spread• Eating infected food

• Contact - between healthy and infected stock

Introduction to EDR 15

How Disease Can Spread…..

• Contaminated objects

• Vectors, carriers and intermediate hosts

• Air (least common)

Achoo

Introduction to EDR 16

Speed and Extent of SpreadDepends on:• Number/range of host species• Method/s of spread• Whether the unwanted organism survives

outside the host and for how long• How easily it is detected• How early it is detected (incubation period)

Introduction to EDR 17

The Exotic Disease LifecycleBSE• Unwanted organism = prion• Cattle get BSE by eating infected bone or

meat meal • 4-7 years before shows up as infected• Very long lifecycle• In UK 1-4 m animals infected before the

disease showed up

Introduction to EDR 18

The Exotic Disease Lifecycle….Foot and mouth• Unwanted organism = virus• Spread by eating infected food and by

contact • Rapid spread• Short incubation period

Introduction to EDR 19

Early detection depends on:• Awareness of farmers and vets• How clear the signs are• How long it is before the signs show

Time is of the essence

Detection

Introduction to EDR 20

3. Exotic Disease Response Objective

By the end of this topic you will be able to:• list and describe the three response structures• describe your own role or roles in an exotic disease

response, and• define key terms relating to exotic disease response.

Introduction to EDR 21

Exotic Disease Response

• Response structures• Generic processes and procedures• Then for each response

– Response plan– Response objectives

Introduction to EDR 22

Response Structures

Surveillance

Organism Management

Movement Control 1. To halt spread of the disease

2. To eradicate the disease from infected properties

3. To quickly identify any new infections and ensure early intervention.

Introduction to EDR 23

EDR Process

Introduction to EDR 24

EDR Process Example….The start• A farmer notices a problem – perhaps an

unusual number of abortions, and calls the vet

• The vet suspects an exotic disease infection• The vet calls MAF – 0800 number• MAF send an authorised person to perform

surveillance

Introduction to EDR 25

EDR Process….

Disease present (or suspect)• Treatment starts (Organism Management) • Movement control starts (Movement Control)• Investigation and tracing starts (Surveillance)

Introduction to EDR 26

Movement Control

Introduction to EDR 27

Organism Management• Restricted place management and security• Destroy infected stock• Treat stock• Clean and disinfect etc.

Introduction to EDR 28

Surveillance• Investigations – inspections, sampling • Tracing• GIS (Geographic Information System)
