Disinfection of stables and premises

Question 1

Condition

Answer 1

◦ Crew must be mentally, physically fit and healthy ◦ Proper education, training of the workers
◦ Proper clothing and tools
‣ Boots, Water resistant clothing, gloves, helmet, Gas mask, Protective eyewear
◦ If animals are still inside–> not toxic disinfectants
◦ No eating, drinking, smoking
◦ In case of use of cc.acid or base–> cleaning of the skin is important
◦ Protection of the buildings and tools
‣ High pressure washing systems

Question 2

Calculation of the amount of disinfectants

Answer 2

◦ Depends on: Quality of the surface, Size of the surface, Cleaning prior to the disinfection
◦ High pressure washing systems (10-20bar) for every m2: ->Foil (smooth surface) 0,1 liter, concrete, tile 0,2 liter, Planking or whitewashed surface 0,5 liter, Bricks1
liter, Clay1,5 liter, Loose surface, sand 3,0 liter.
◦ In case of low pressure washing systems: 1,5*

Question 3

Process

Answer 3

• remove everything
• emptying of the drinkers, feeders
• physical cleaning of ceiling, walls, floor, ventilation system
• strip out all equipment for cleaning
• dust removal, cut the power, soaking (1.5-3h detergent/foam, active substance can go into small cracks)
• wash with high pressure washing system (roof-> walls–> floor), wet all surfaces, extra attention to corners/ cracks/ seams
• porous surfaces!!
• cleaning surroundings (4% oschlorine base)
• closing of the building
• equipment check before reinstall

Question 4

Disinfection of drinkers

Answer 4

◦ Removal of the water
◦ Physical cleaning brushing
◦ 1 g Neomagnol pulv. techn., or
◦ 1 Neomagnol tabl./ 10 l water, 2 hours
◦ 0,1 g chlorinated lime/ 10 l water, 2 hours(must smell like Cl2 after two hours)

Question 5

Disinfection of wells

Answer 5

◦ Identification of the source of infection
◦ Emptying the well
◦ Chlorinated lime, chlorine-base
◦ No water removal for 24hours!
‣ Pour it into the well (tube)
‣ Maximum 30-40mdepth
‣ If deeper contact local authorities
◦ Cisterns: Like normal wells, But double dose of lime or chlorine-base
◦ 24h later water must have: Chlorinated smell, Chlorinated taste–> If not, disinfection must be repeated–>Before that water must be removed
◦ Driven well must be pumped until the water is odorless

Question 6

Disinfection of the water system (tubes)

Answer 6

◦ Ca-, Mg, “biofilm” (protozoa, algae, bacteria)
◦ CID2000 (210g hidrogen-peroxid, 55g peracetic-acid 10g acetic-acid/l)
◦ High cc before the animals for cleaning and disinfection
◦ 80% of the effectiveness last 18-20hours
◦ Low cc, every other day, disinfection of the water

Question 7

Monitoring the efficiency of disinfection

Answer 7

• direct swabbing techniques with media
  1, Stuart: Neisseria, Haemophilus, Diphteriae, Trichomonas, Strep., Salmonella, Shigella
  2, CaryBlair: Neisseria, Haemophilus, Strep.
  3, Amies: Neisseria, Trichomonas, Corynebacteria, Haemophilus, Strep., Enterobacteraceae
• quantitative monitoring
• ready to use tests - Boot Swabs
