Quiz 13: Biosecurity

What is an isolation/quarantine unit? An area where animals are reared in order to facilitate their exposure to pathogens An area where animals can be isolated and tested prior to introducing them to a herd A facility from which disease-free animals can be purchased A farm where animals are kept to recover from disease

An area where animals can be isolated and tested prior to introducing them to a herd

Which of the following are common fomites able to spread pathogens on farms or in clinics? Animals, semen, and boots Boots, syringes, and utensils Flies, gloves, and trucks Rodents, boots, and air

False

Regarding livestock loading and unloading, which factor supports principles of biosecurity? Allowing the truck for carcass collection onto the farm A shorter race that ends before the perimeter Farmers not assisting at the truck Truck drivers entering the facility

Farmers not assisting at the truck

Bioexclusion is: Management of disease within populations More important in large animal than in small animal populations Prevention of disease from entering populations of animals Prevention of disease transfer between animals and people

Prevention of disease from entering populations of animals

An appropriate protocol for ensuring that pathogens are inactivated from surfaces includes: Drying of organic material before applying disinfectant. Removal of organic material before applying disinfectant. Use of disinfectants that can inactivate pathogens in organic matter. Washing with cold water before applying disinfectant.

Removal of organic material before applying disinfectant.

Which of the following is NOT associated with time that a given organism remains infectious on a fomite? Environmental temperature Level of disinfection Amount of sunlight Species of animal exposed

Species of animal exposed

Which of the following is a component of biosecurity guidelines for visitor control? Do not allow visitors to wash their hands while on the premises. Ensure visitor parking in the same area used by farm vehicles. Prohibit all visitors that have been on other farms within the previous week. Supply clean clothing and boots on the farm for all visitors.

Supply clean clothing and boots on the farm for all visitors.

A primary goal of biosecurity measures is: Identification and removal of infected animals. To ensure all animals are treated for external parasites. To prevent the introduction of pathogens in a population. To promote the spread of pathogens in a population.

To prevent the introduction of pathogens in a population.

Which of the following practices employed by the University's West Metro equine practice follows a principle of biosecurity for equine farms visited? Keeping a first-aid kit on each truck and in the clinic Minimizing drug inventory and tightly monitoring drug expiration Storing controlled drugs inside the clinic instead of out on the locked truck overnight Using disposable plastic boot covers when visiting farms housing horses with potentially infectious diseases

Using disposable plastic boot covers when visiting farms housing horses with potentially infectious diseases

Which of the following denotes a visitor as low risk? Visitor does not change coveralls between farms if they appear clean. Visitor does not travel out of the country. Visitor owns and cares for other species than those housed on the farm. Visitor visits one or occasionally more than one other farm daily.

Visitor does not travel out of the country.
