To find the CB bacteria in raw milk is something to expect. Other reports mentioned 40% to 60% positive restresults of bulkmilk (cows) in the USA, Netherlands, Sweden, Denmark.
When you pasteurise the milk, most of the CB bacteria is gone, depending on the temperature of the process.
Recently we had a Q-fever outbreak in the Netherlands, several thousands of patients and 16 deaths were reported. Many patients were screened.
No patient was found to be contaminated via milk or dairy products.
Typically human infection occurs through contaminated dust.

Abstract
Unpasteurized (raw) milk can be purchased in 39 U.S. states, with direct consumer purchase for human consumption permitted in 29 of those 39 states. Raw milk (n = 21; cow, 14; goat, 7) was purchased in 12 states, and Coxiella burnetii, the agent of Q fever, was detected in 9 of 21 (42.9%) samples tested by polymerase chain reaction. Viability of the pathogen was demonstrated by isolation of the agent in tissue culture.
The demonstration of viable C. burnetii in commercially available raw milk poses a potential public health risk.
