TRUSTED INFECTION CONTROL
What is Infection Control?
Infection control addresses factors related to the spread of infections
Animal to animal (different species – Zoonotic)Animal to staff and from staff to animalamong-staff
These processes include preventionIsolation, limiting movementCleaning and disinfectionhand hygiene/hand washing, vaccination, surveillance / monitoring / investigation
TRUSTED INFECTION CONTROL
Animals from a variety of sources endemic disease, carrying / incubating infectious
Shelter may have endemic organismsGiardia, Ringworm, etc.
Animals subject to stress entering the ShelterPotential immune system impairmentIncreased susceptibility to disease
WHERE’s THE RISK?
TRUSTED INFECTION CONTROL
PHYSICAL BARRIERSISOLATION pending CLEAR BILL OF HEALTH
Animal specific equipment, food and water bowls, leads, collars, etc.Separate exercise areas
OPERATIONAL BARRIERSDo not relocate or allow movement into general populous for (5-7 DAYS) vigilant in identifying disease / regularly assessStaff managing High Risk cases should not handle puppies / kittens
TREATMENT AND INTERVENTIONNew entrants to be Veterinary examinedCommence Vaccination course asap Treatments for parasitical infections

Appropriate Disinfectants
• The following should be paramount when choosing a disinfectant: -– A wide range of microbiological activity with
supporting test evidence (Parvovirus, FIV, FCV, Herpes, etc.)
– Activity in DIRTY CONDITIONS– Compatibility with materials (metal, rubber, plastics,
cloth, etc.)– Safe to Use– Economic - simple dilution ratios– Wide range of applications– Long shelf life in diluted format
