The 3 are effects that the toxin can have on an organism.
A mutagenic toxin is capable of producing mutations in living organisms (eg 5-bromo-uracil).
A cancerogenic toxin is able to cause or promote cancer in an individual who consumes it (example: benzene).
A teratogenic toxin can produce congenital malformations, ie when a pregnant woman consumes this toxin, the new born may have a malformation at birth (example: thalidomide).
