Principles of non-foodborne zoonosis control in food producing animals Flashcards
What percentage of new or emerging pathogens are zoonotic?
75%
What factors are involved in the emergence of zoonoses?
Environmental changes Human and animal demographics Pathogen changes Changes in farming practices Social and cultural factors -Food habits -Religious beliefs -Use of countryside
What types of transmission pathways can zoonoses have?
Direct
Indirect
Vector-borne
What is the difference between a reportable and notifiable disease?
Notifiable = report when disease is suspected Reportable = the lab isolating the pathogen makes a report
In which group of bacteria is the development of resistance a particular problem?
Gram negatives
What are the elements of risk analysis?
Risk assessment
Risk management
Risk communication
What components may make up a risk assessment?
Prevalence
- geography
- animal species
- production system
Biology
- transmission pathways
- survival in environment
- infective dose
Consequences of human exposure
What are veterinary surgeons obliged to implement under CoSHH regulations?
Personal protective equipment (PPE) Good hygeine Sanitation and disinfection Appropriate waste disposal Isolation facility use Education of owners
How should vets implement CoSHH regulation on farms?
Assesss risks of microorganisms
Prevent or control exposure to these/hazardous substances
Introduce and maintain control measures
Regularly review assessments
How can exposure to pathogens on farms be prevented?
-Keep animals healthy! e.g. vaccination, management & husbandry Use PPE Hygiene Control pests/vermin Detect and report stuff
Why are zoonoses typically underreported?
Lack of awareness
sub-clinical infecitons
Minor clinical signs
What is RIDDOR
Reporting of injuries, diseases and dangerous occurences
