Which of the following is the gold standard post-exposure prophylaxis regimen for unvaccinated humans exposed to rabies?
Answer: Rabies immune globulin at wound site plus vaccine series (days 0, 3, 7, 14)
PEP for unvaccinated individuals requires infiltration of rabies immune globulin at the wound plus a 4-dose vaccine series to provide immediate and long-term protection.
Coxiella burnetii (Q fever agent) is classified as a Category B bioterrorism agent. Which animal reservoir is the primary source of human infection?
Answer: Domestic ruminants (cattle, sheep, goats)
Cattle, sheep, and goats are the primary reservoirs; parturient materials (placenta, birth fluids) contain extremely high concentrations of C. burnetii.
Under the 21 CFR Part 117 Preventive Controls rule, which of the following is classified as a 'process control'?
Answer: Cooking step that kills pathogens to a safe level
A process control is a procedure such as cooking that applies a lethal treatment to eliminate or reduce a biological hazard to an acceptable level.
A slaughter plant veterinarian observes a pig with depression, erythematous skin lesions, and sudden death in the pen. The most important zoonotic differential diagnosis to consider is:
Answer: Erysipelothrix rhusiopathiae infection
Erysipelothrix rhusiopathiae causes erysipelas in swine and can cause erysipeloid in humans who handle infected carcasses.
Which epidemiological measure best quantifies the additional risk of disease attributable to a specific exposure?
Answer: Attributable risk (risk difference)
Attributable risk (risk difference) measures the excess disease burden among the exposed group that is directly attributable to the exposure.
Which critical temperature range is considered the 'danger zone' for bacterial growth in potentially hazardous foods?
Answer: 40°F to 140°F (4°C to 60°C)
The USDA defines the temperature danger zone as 40°F to 140°F (4°C to 60°C), where most foodborne pathogens multiply rapidly.
Methicillin-resistant Staphylococcus aureus (MRSA) has been identified as an occupational zoonosis. Which livestock species is most closely linked to the LA-MRSA (livestock-associated MRSA) ST398 strain?
Answer: Swine
LA-MRSA ST398 is strongly associated with swine and pig farm workers, representing a major veterinary public health concern.
