What is not a recommended method to prevent Q fever infection in laboratory workers?

Relying on serology in sheep to detect shedding of the organism is not a recommended method to prevent Q fever infection in laboratory workers. Serological testing may indicate the presence of antibodies in sheep, signaling past exposure to Coxiella burnetii, the causative agent of Q fever. However, this approach does not effectively monitor or prevent active shedding of the organism at present, which is critical for protecting laboratory personnel.

Instead, proactive measures such as using male sheep, wearing appropriate personal protective equipment (PPE), and employing respirators when handling pregnant sheep or their tissues are emphasized for minimizing the risk of infection. These methods promote direct reduction of exposure to the pathogens that may be present in the environment or during specific procedures, thereby enhancing the safety of laboratory workers.
