Coxiella burnetii is shed in the milk of infected animals.

• A. True
• B. False
• C. Only in colostrum
• D. Only during lactation first month

Answer: (A)

Coxiella burnetii is shed in milk of infected animals, not just in colostrum and not only during a brief early lactation window. Infected ruminants can excrete the organism in milk during lactation for extended periods, especially around parturition, as part of multiple routes of shedding (including birth fluids, urine, and feces). Because of this, milk can be a source of infection if consumed unpasteurized, but pasteurization greatly reduces risk. So the statement is true.
