Clinical microbiological waste. Petri dishes in a clinical waste bin marked with a biological hazard symbol. The petri dishes contain agar (red) that has been used to culture (grow) microbes in a hospital pathology laboratory. This allows the diagnosis of diseases. Because they are a potential source of infection, the petri dishes must be disposed of in labelled bins and incinerated.
