Biosecurity Flashcards
biosecurity
• Management practices that reduce the opportunity for infectious agents to gain access to, or spread within, an animal production unit.
• Ongoing pressure on agriculture to reduce antimicrobial usage has
led to increased emphasis on disease prevention and the role of biosecurity.

why the concern
• Foreign and emerging disease issues
• Globalization of agriculture
• Increased public concern over food safety
• Farms are less isolated
• Farm inputs coming from farther away sometimes other
countries.
• FAD such as: FMD, BSE, AI, and Newcastle disease have
brought world concerns closer to the local farm/ranch level.
level 1
protect against diseases endemic to the local environment
level 2
secure against foreign or exotic diseases
who is concerned with it
- Neighbors and Friends
- Agribusiness and Service representatives
- Veterinarians
- Inspectors/regulatory personnel
- Rendering
- Custom manure/biosolids haulers and applicators.
- Any Visitor
assessing visitor risk
• Place restricted entry notices on the doors to
animal facilities.
• Separate visitor and farm vehicle parking
•All visitors enter at one point. Keep a log.
•Know where farms visitors may have been to prior
to your farm
•Restrict access to animal facilities to essential
visitors only
reduce exposure
• Supply clean clothing, boots, or covers
• Do not allow foods of ANIMAL ORIGIN to be brought on
premises
• Provide containers to properly dispose of dirty clothing and
equipment.
• Always wash hands after contacting animals
• Foot bath with scrub brush at entrance to each animal
facility. (clean daily)
• Clean to dirty. Handle sick animals last.
• Clean and disinfect all equipment before use on premise
• Ensure parameter control
• Control human traffic
• Control animal traffic
• Add known-status animals
• Isolate all new additions
• Isolate diseased animals
• Vector and vermin control
• Ensure pasture and paddock management
• Parasite control
• Practice waste management
• Appropriate carcass disposal
waste management
- Biohazard waste
- Medical waste
- Wastes of environmental concern
- Sharps
- Clothing
- Gloves
- Other PPE
animal carcass disposal
- Burial
- Mass depopulation
- Environmental concerns
- Local jurisdictions
- Rendering
- Carcass storage concerns
- Transport concerns
- Composting
- Land available?
- Disease spread?
- Incineration
- Costly
- Disease spread?
concerns with manure
- Many important diseases are transmitted by manure and clothing and equipment contaminated by manure.
- Bacterial
- Salmonella, E. coli, Johne’s disease, Tuberculosis
- Viral
- Hog cholera, FMD, BVD
- Protozoal
- Coccidiosis, cryptosporidiosis
- Parasitic
- Ascariasis, sarcocystosis.
manure haulers and rendering
•Hiring custom haulers/renderers increases potential
spread of disease between farms
•Wash all exterior surfaces of manure handling
equipment; check all are visibly free of organic
matter prior to farm entry.
•Consider on property lagoons, digestors.
•Manure recycling strategies
• Disease spread (compost)
• Fertilize fields
• Source of energy production
protecting against infection
- Vaccination
- Laboratory testing
- On-premise surveillance
- Single in and out
- House according to disease status
- Cleaning
- Disinfection
- All in all out
people managment
- Employees
- PPE
- Dedicated clothing
- Shower facilities
- Work clean to dirty
- Visitors and vendors
- Controlled access
- PPE
animal identification
•Electronic identification : birth to consumption
•Verification of records
•Tracking for epidemiological purposes,
disease outbreaks.
