Answer:
The current answer is a. Bacterial culture
Explanation:
Bacteria are used in epidemiology laboratory and bacteria can spread and cause disease if the correct lab procedures are not followed.
So according to the lab safety sheet bacterial culture is the potential hazard that will be present in the laboratory during the Epidemiology & Laboratory Techniques lab. There are different levels of biosafety according to the threat posed by the bacterial culture on which epidemiological study is going on.
The biosafety sheet helps in featuring the epidemiology of bacterial culture, transmission mode, availability of medical interventions, suggested biosafety levels, etc. So the right answer is a.
