6: data analysis and decision making
7: reporting back and future monitoring
What is biosecurity?
The prevention of disease agents entering a non infected farm
What is bio containment?
Prevention of disease spreading with in an infected farm or leaving a farm?
What are the levels of biosecurity?
Global, regional, national, and local
What are the risk factors for crossing of pathogens?
Increased herd size, purchase of animals, purchasing advice, vet have no effect
What are the tools for disease control?
Test and cull Vaccination Movement restriction Compartmentalization Surveillance
What is the overarching factor of the tools of disease control?
Who pays for it?
What is surveillance?
It is the repeated measurements recording and review of data related to the occurrence of events such as disease
What are the basic principles for disease controll?
Find it
Fix it
Kill it
KEEP IT OUT
What are the Reporting pathways for disease?
Department for environment food and rural affairs ( OIE)
Animals and plant health agency (European union)
Public health England (WHO)

Involvement in investigation and potentially response
Use of surveillance data for your work
Education and raising awareness

What is risk?
An estimate of the probability and severity of the adverse health effects in exposed population, consequential to hazards in food
What are the main hazards in food?
Biological: bacteria, parasites, and viruses
Chemical: drug residues, contaminants
Physical: foreign bodies, metal or glass contamination
What is risk management?
Prevention Control Alternative options Implementation Monitoring Evaluation
Who are the key stakeholders in food law?
The food business
The state
The consumers
What are the key components in risk management?
Food safety and management systems Risk based approach Precautionary principle Traceability EFSA RASFF
What is the most effective food safety management system?
HACCP (Hazard Analysis Critical Control Point)
Describe the food safety pyramid
Lowest tier: prerequisites to legal requirements( water quality, pest, hygeine, ect.)
Middle tier: HACCP legal FSMS requirement
Top tier: BRC, voluntary and beyond legal requirements usually relate to consumer requirements
Describe the risk based approach?
Food law should be based on risk and follow risk analysis( EFSA)
What is the precautionary principle?
Whenever here is possibility of harmful effects and scientific uncertainties there is the right to take provisional risk management measures. The measure must me proportionate and not purposefully trade restictive.
What is traceability?
Follow to course of food through all stages from animal feed to retail. Must be able to go ones temp forward or back for all stages.
All animals sent for slaughter have to traceable
What is RASFF?
Rapid Alert System for Food and Feed: a system of notification for countries that included contact points at: member states( UK:FSA)
Commission
EFSA
