Factual error: The container for the dangerous biological material is marked "Biohazard Level 5." There is no level 5. According to CDC regulations Biohazardous materials are rated 1 through 4. Based on the description of the material in the episode, it would be required to be stored in a laboratory rated at Biosafety Level (BSL) 4. All BSL 4 labs require personnel to wear a fully enclosed, pressurized suit when inside the lab. (00:01:05)
Continuity mistake: Lisbon is telling the CDC agent that the scientist's death is a homicide. The agent has an ear piece in his left ear in close-up shots. In all other shots, the piece isn't in his ear.
