If Brucella suspected and/or confirmed samples or cultures are being handled in a laboratory, at what biosafety level should personnel be working?

Brucella requires containment at the highest level typically used for routine clinical pathogens because it is a respiratory pathogen with a relatively low infectious dose and lab procedures can aerosolize it. Handling suspected or confirmed Brucella cultures or samples poses an inhalation risk, so the work must occur in a Biosafety Level 3 environment. BSL-3 provides negative‑pressure facilities, certified biosafety cabinets for aerosol-generating steps, controlled access, and appropriate PPE with respiratory protection, along with procedures for entry, decontamination, and medical monitoring. Lower levels do not offer sufficient protection against aerosols, and the highest level is not necessary for Brucella. Therefore, BSL-3 is the appropriate standard.
