intro to biosecurity Flashcards
zoonoosis
any disease or infection which is naturally transmissible from vertebrate animals to humans
biosecurity
strategic and integrated approach to analyzing and managing relevant risks to human, animal and plant life and health associated risks for th environment
emergency biosecurity
in the face of a specific threat
routine biosecurity
everyday control of disease spread
name some forms of biosecurity
infection control, aseptic technique, management of notifiable/ emergency animal disease, management of GMOs, bioterrorism
who manages animal biosecurity (international)
WOAH world organization for animal health
who manages animal biosecurity (national)
department of agriculture, fisheries and forestry (DAFF)
animal health australia (AHA)
who manages animal biosecurity (state)
state dept. Ag or primary industries
where is biosecurity particularly a risk
hobby farms (high diversity of animals, not professional farms, not regularly checked, high movement of animals and people on and off farm)
general personnel biosecurity approaches
clothing, PPE, hand hygiene, vaccines
goal of biosecurity approaches
- intro to pop
- spread through pop
- maintenance in pop
- specific transmission
fomite
object that can carry and spread diseases
biosecurity general approaches engineering controls
facilities and equipment, design, cleaning and decontaminations, materials
biosecurity general approaches administrative processes
processes, protocols, methods, quarantine, isolation, waste disposal
PPE
personal protective equipment
-protection of self
-last line of defence
physical containment (PC) levels PC1-PC4
PC facilities are designed to ensure that infectious microorganisms are safely contained inside the lab
our labs are PC2, one PC4 facility in australia
quarantine vs isolation
stopping disease from coming in vs stopping disease from spreading
SOPs
standard operating procedures
how to choose level of PPE
risk= probability x impact
skin/ membrane penetration
how, what, what to do
bites, scratch, sharps, etc
lepto, anthrax, rabies, etc
doctor, soap, water, antiseptic’s, antibiotics, etc
contact zoonoses
ringworm, scabies, hookworm
hand hygiene, PPE, dewormer, remove environmental exposures
inhaled zoonoses
hendra, q fever, influenza, covid 19
avoid high risk areas, PPE masks and respirators, ventilation, disinfection, vaccines
ingested zoonoses
e.coli, salmonella, giardia
hand hygiene, nothing in mouth while working, food areas separate
vector borne zoonoses
ticks; typhus
fleas; plague
mosquitos; arbovirus
etc
chemical and physical preventatives
baseline level of PPE
boots, overalls, hand hygiene, sharps, etc
mid level of PPE
baseline plus gloves
maybe a mask, disposable apron
high level PPE
mid level plus definitely P2 mask or respirator, double gloves, face shield, others
