Question 1

Which of the following is the most common route of Leptospirosis transmission to NWCO operators working with raccoons or rats?

Accepted Answer

Contact of mucous membranes or broken skin with urine-contaminated water or soil

Answer

Leptospira bacteria are shed in the urine of infected animals. Transmission most commonly occurs when the organism contacts mucous membranes or abraded skin, making glove use and eye protection critical when handling urine-soaked materials or working in flooded areas where rodents and raccoons frequent.

Question 2

An NWCO operator is removing a dead skunk from beneath a deck without visible injury to the animal. What is the primary zoonotic concern that still warrants the use of heavy-duty gloves and a face shield?

Accepted Answer

Rabies virus surviving in neural tissue even after the animal's death

Answer

Rabies virus can remain viable in neural tissue (brain and spinal cord) of a recently deceased animal. Operators must treat any intact carcass of a high-risk species as potentially infectious, because puncture wounds from teeth or claws during handling can still transmit virus from neural tissue.

Question 3

Ringworm (dermatophytosis) found in wildlife such as foxes and opossums is caused by:

Accepted Answer

A fungal pathogen transmitted by direct contact with infected fur or bedding

Answer

Despite its name, ringworm is a fungal infection (tinea corporis) caused by dermatophytes. NWCO operators can contract it through direct contact with infected animals or contaminated cage bedding. Wearing gloves and laundering clothing after each job prevents transmission.

Question 4

When an NWCO operator must enter an attic with a large, long-established raccoon latrine, the MINIMUM respiratory protection recommended by wildlife health authorities is:

Accepted Answer

A half-face respirator fitted with P100/HEPA filters

Answer

Raccoon roundworm (Baylisascaris procyonis) eggs and other pathogens in dried feces become airborne during disturbance. A half-face respirator with P100/HEPA filters is the minimum standard because it removes particles down to 0.3 microns, capturing infective eggs that a dust mask or surgical mask cannot reliably filter.

Question 5

Salmonellosis is a concern when NWCO operators handle which commonly encountered wildlife species?

Accepted Answer

Reptiles such as snapping turtles, as well as birds including Canada geese and starlings

Answer

Reptiles are well-documented Salmonella reservoirs, and many bird species — including Canada geese and European starlings — shed Salmonella in their feces. NWCO operators handling these animals or cleaning contaminated sites should wear gloves and avoid touching their face, then wash hands thoroughly afterward.
