Biosecurity
- “Protection from exposure to disease”
- What?
- Why?
- How?
Biosecurity
“A set of management practices which when followed correctly reduce the potential for the introduction and spread of disease causing organisms onto, and between sites.”
From the perspective of the animal rather than just the farm
Biosecurity
Control of “Management Diseases”
Calf Pneumonia
Calf Scours
High cost to the industry worldwide
Mortality
Poor growth
Poor Feed conversion
Cost of Medication
Biosecurity
Requirements of the Dairy Farm
Maintenance of stock health
Protecting the production potential
Protecting the quality of the product
Maintain Standards in all areas
Cubicles
Calving Facilities
Calf rearing
Collection Area
Milking Parlour
Dairy
TYPES OF DISINFECTION
- Terminal
- Continuous
STAGE 1REMOVAL & DRY CLEAN
- Remove stock
- Equipment
- Bedding
- Gross organic waste
- Dust
STAGE 2CLEANING & SANITIZATION
- Reducing infective material
- Removal of dried on matter
- Use a Detergent / Sanitizer
- Allow to dry afterwards
STAGE 3AWATER SYSTEMS
- Drainable
- Drain
- Clean
- Disinfect
- Flush
- Non-Drainable
- Clean
- Sanitize
STAGE 3BREMOVABLE EQUIPMENT
- Soak
- Scrub / Pressure Wash
- Detergent Sanitizer
- Disinfect
- Dry
STAGE 4DISINFECTION
- To remove residual challenge
- Use broad spectrum disinfectant
- Cover all surfaces
- Cover all cracks & crevices
- Allow to dry.
STAGE 5AERIAL DISINFECTION
- Covers inaccessible areas
- Replace movable equipment first.
- Can be done after bedding is spread.
- Fog / Fumigate
- Safety required with formaqldehyde.
- Rest period
Control Access
Foot & Wheel Dips
Water Sanitization
Aerial Disinfection
Rodent Control
CONTINUOUS DISINFECTION
Cattle Biosecurity
Calving
Clean the building of all organic debris
Pressure wash
Spray broad spectrum ddisinfectant
After each calving remove bedding, cleansing and discharges
Clean and disinfect
Clean and disinfect buckets and utensils
Cattle Biosecurity
Cow Cubicles
Control of Mastitis Pathogens
Regularly clear organic debris
Pressure wash with detergent sanitiser
Disinfect cleaned surfaces
Scrape central channel at least daily
Reguarly clean and disinfect equipment and utensils
Cattle Biosecurity
Milking Parlour and Dairy
High standards Practiced
Use broad spectrum disinfectants after cleaning in the parlour
Cattle Biosecurity
Care of housed calves
- Pneumonia and scours cost the industry vast sums
- Effective hygiene can prevent these two diseases
- Situation similar to other intensive species
- Poor ventilation, overcrowding and stock movements contribute
- Hygiene is essential
Cattle Biosecurity
Cattle vehicle Biosecurity
- Only essential vehicles to enter farm
- Keep visiting vehicles outside biosecurity perimeter if possible
- Vehicles should be cleaned and disinfected before arrival at the farm
- Wheels, tyres and Wheel arches should be disinfected on arrival
- Personnel should use foot dips, protective clothing and observe hand hygiene
Conclusion
Freedom from Disease = Maximum Profits
