Infectious substances are substances containing micro-organisms (such as bacteria) or toxins which can cause disease in animals or humans eg Salmonella, Lepterospirosis, Hepatitis, etc

Hazardous Effects:
There are four main routes by which Class 6 substances can enter the body:
ingestion (swallowing)
